Ventricular myocytes are heart muscle cells found in the lower chambers of the heart. Heart rate is dependent on the movement of an electrical stimulus through the individual heart cells. This is mediated by the opening of ion channels on cell surfaces. HBI-3000 exerts its effects on the heart by inhibiting multiple ion channels (INa-F, INa-L, ICa-L and IKr), but predominantly the INa-L ion channel .

The heart is a biological pump designed to move blood through the brain and body. It has four chambers: two "upper" chambers called the atria, and two "lower" chambers called the ventricles. Anatomically, the atria are more posterior to the ventricles, but for ease of understanding, are often drawn "above" them. The atria are separated from the ventricles beneath by the atrioventricular valves, which open to allow blood into the ventricles and close when ventricular pressure exceeds atrial pressure.

Pumphouse No. 1, a small one-storey reinforced concrete structure, was completed in 1937 to the immediate south of the Low Pressure Plant. Below the pumphouse is a series of lower chambers, catwalks which extend to a depth of 50 feet below grade. The engineering on the pumphouse was completed by John Poole following his graduation from the University of Alberta. Pumphouse No. 1 remains standing in the Edmonton River Valley, and continues to house the original machinery.

Third-degree AV block occurs when the signal between the atria and ventricles is completely blocked, and there is no communication between the two. None of the signals from the upper chambers make it to the lower chambers. On ECG, there is no relationship between P waves and QRS complexes, meaning the P waves and QRS complexes are not in a 1:1 ratio. Third-degree AV block is the most severe of the AV blocks.

The interventricular septum (IVS, or ventricular septum, or during development septum inferius) is the stout wall separating the ventricles, the lower chambers of the heart, from one another. The ventricular septum is directed obliquely backward to the right and curved with the convexity toward the right ventricle; its margins correspond with the anterior and posterior interventricular sulci. The lower part of the septum, which is the major part, is thick and muscular, and its much smaller upper part is thin and membraneous.

When Mailata was 17, he fainted during a rugby league workout, and needed emergency surgery to repair both the upper and lower chambers of his heart. He went on hiatus from rugby league for a year and then played for the South Sydney Rabbitohs. After seeing clips of him playing rugby league, NFL executives invited Mailata to tryout for their International Pathway Program. He went to Florida to train, and his training was part of the NFL Network show Undrafted.

Atrioventricular block (AV block) is a type of heart block that occurs when the electrical signal traveling from the atria, or the upper chambers of the heart, to ventricles, or the lower chambers of the heart, is impaired. Normally, the sinoatrial node (SA node) produces an electrical signal to control the heart rate. The signal travels from the SA node to the ventricles through the atrioventricular node (AV node). In an AV block, this electrical signal is either delayed or completely blocked.

Century Pit lies to the east of Moss Pit, with an entrance in diameter. Surrounded by a wall of spatter material ranging from in height, it has a vertical drop of , its lower half widening to a chamber with dimensions of at its base. The western margin of the base has an opening about deep, and at that depth it is blocked by debris. The lower chambers for both pits may be influenced by a fissure or may form part of an open fissure vent.

The collagenous cardiac skeleton which includes the four heart valve rings, is histologically, elastically and uniquely bound to cardiac muscle. The cardiac skeleton also includes the separating septa of the heart chambers – the interventricular septum and the atrioventricular septum. Collagen contribution to the measure of cardiac performance summarily represents a continuous torsional force opposed to the fluid mechanics of blood pressure emitted from the heart. The collagenous structure that divides the upper chambers of the heart from the lower chambers is an impermeable membrane that excludes both blood and electrical impulses through typical physiological means.

Rhabdomyoma vary in size from a few millimetres to several centimetres, and are usually found in the lower chambers (ventricles) and less often in the upper chambers (atria). They grow in size during the second half of pregnancy, but regress after birth, and are seen in only around 20% of children over two years old. Most rhabdomyomas cause no problems but some may cause heart failure in the foetus or first year of life. Rhabdomyomas are believed to be responsible for the development of heart arrhythmia later in life, which is relatively common in TSC.

It is designed to allow two (or more) same-party members share a particular congressional seat during a single political term, which lasts four years (2+2=4). This is permitted by means of well manipulated Constitutional loopholes orchestrated by the political party who usually holds the executive branch seat (Head of State) and/or has congressional majority (both in upper and lower chambers). It has been used mostly by the PRD party which coined the term themselves, but it may apply to the other two main Dominican parties.

In 1942, it was decided that an alternate entrance was required to improve air circulation within the emergency hospital in the lower chambers of the cave, as well as to serve as an emergency exit in case of airstrike. Whilst blasting the rock in order to create the extra opening, another deeper system of caves known as New St. Michael's Cave (sometimes referred to as Lower St. Michael's Cave) were discovered. The series of descending chambers are riddled with examples of almost all known cave formations, including an underground lake of crystal clear water.

The upper two chambers, the left and right atria, are entry points into the heart for blood-flow returning from the circulatory system, while the two lower chambers, the left and right ventricles, perform the contractions that eject the blood from the heart to flow through the circulatory system. Circulation is split into pulmonary circulation—during which the right ventricle pumps oxygen-depleted blood to the lungs through the pulmonary trunk and arteries; or the systemic circulation—in which the left ventricle pumps/ejects newly oxygenated blood throughout the body via the aorta and all other arteries.

Decisions on the next meeting are made when the Speakers get together for the annual meeting. In the case of a bicameral legislature, participation is not restricted either to the upper or lower chambers. Members of parliament can join official delegations as well as diplomats based in the host country. The President of the Senate of the United Mexican States, the Chairman of the Regional Representatives Council of the Republic of Indonesia (upper chamber), and the President of the Senate of the Commonwealth of Australia attended the 1st MIKTA Speakers' Consultation, which was held in Seoul, 2015.

Examples of "apparent" staircases are Foxton Locks and Watford Locks on the Leicester Branch of the Grand Union. Instructions for descent of treble staircase, Chesterfield Canal Operation of a staircase is more involved than a flight. Inexperienced boaters may find operating staircase locks difficult. The key worries (apart from simply being paralysed with indecision) are either sending down more water than the lower chambers can cope with (flooding the towpath, or sending a wave along the canal) or completely emptying an intermediate chamber (although this shows that a staircase lock can be used as an emergency dry dock).

Beginning of the interventricular septum shown at 28 days The interventricular septum is the stout wall separating the ventricles, the lower chambers of the heart, from one another. The ventricular septum is directed obliquely backward to the right, and curved with the convexity toward the right ventricle; its margins correspond with the anterior and posterior longitudinal sulci. The greater portion of it is thick and muscular and constitutes the muscular interventricular septum. Its upper and posterior part, which separates the aortic vestibule from the lower part of the right atrium and upper part of the right ventricle, is thin and fibrous, and is termed the membranous ventricular septum.

Many modern ICDs use a combination of various methods to determine if a fast rhythm is normal, supraventricular tachycardia, ventricular tachycardia, or ventricular fibrillation. Rate discrimination evaluates the rate of the lower chambers of the heart (the ventricles) and compares it to the rate in the upper chambers of the heart (the atria). If the rate in the atria is faster than or equal to the rate in the ventricles, then the rhythm is most likely not ventricular in origin, and is usually more benign. If this is the case, the ICD does not provide any therapy, or withholds it for a programmable length of time.

About 75 percent of individuals with Holt–Oram syndrome also have congenital heart problems, with the most common being defects in the tissue wall between the upper chambers of the heart (atrial septal defect) or the lower chambers of the heart (ventricular septal defect). People with Holt–Oram syndrome may also have cardiac conduction disease, or abnormalities in the electrical system that coordinates contractions of the heart chambers. Cardiac conduction disease can lead to slow heart rate (bradycardia); rapid, ineffective contraction of the heart muscles (fibrillation); and heart block. People with Holt-Oram syndrome may have only congenital heart defects, only cardiac conduction disease, both or neither.

Early church architecture did not draw its form from Roman temples, as the latter did not have large internal spaces where worshipping congregations could meet. It was the Roman basilica, used for meetings, markets and courts of law that provided a model for the large Christian church and that gave its name to the Christian basilica. Both Roman basilicas and Roman bath houses had at their core a large vaulted building with a high roof, braced on either side by a series of lower chambers or a wide arcaded passage. An important feature of the Roman basilica was that at either end it had a projecting exedra, or apse, a semicircular space roofed with a half-dome.

The first problem that he faced was that the quarry below the level of the main adit had filled with water in the 17 years that it had been closed. Twelve chambers were submerged, and there were two sumps each holding some of water. Local opinion was that a new tunnel, at the level of the lowest chamber, would need to be cut, and a London-based engineer had calculated that pulsometer pumps could empty it in about six months. As the rails on the main incline to the lower chambers were still in place, Kellow mounted a large centrifugal pump on a platform, which he lowered down the rails as water levels fell.

Passage of a clot (thrombus) from a systemic vein to a systemic artery. When clots in systemic veins break off (embolize), they travel first to the right side of the heart and, normally, then to the lungs where they lodge, causing pulmonary embolism. On the other hand, when there is a hole at the septum, either upper chambers of the heart (an atrial septal defect) or lower chambers of the heart (ventricular septal defects), a clot can cross from the right to the left side of the heart, then pass into the systemic arteries as a paradoxical embolism. Once in the arterial circulation, a clot can travel to the brain, block a vessel there, and cause a stroke (cerebrovascular accident).

Republicans gained a total of 680 seats in state legislative races, breaking the previous record of 628 flipped seats set by Democrats in the post-Watergate elections of 1974. Six states saw both chambers switch from Democrat to Republican majorities: Alabama (where the Republicans won a majority for the first time in 136 years), Maine (for the first time since 1964), Minnesota, New Hampshire, North Carolina (for the first time since 1896), and Wisconsin. In addition, by picking up the lower chambers in Indiana, Ohio, Michigan, Montana and Pennsylvania, Republicans gained control of both chambers in an additional five states. Further, Republicans picked up one chamber from Democrats in Colorado, Iowa, and New York to split control in those states.

In patients with AF where rate control drugs are ineffective and it is not possible to restore sinus rhythm using cardioversion, non-pharmacological alternatives are available. For example, to control rate it is possible to destroy the bundle of cells connecting the upper and lower chambers of the heart – the atrioventricular node – which regulates heart rate, and to implant a pacemaker instead. This "ablate and pace" technique has an important place in the treatment of AF< as it is the only reliably effective method for relieving the symptoms of the arrhythmia and can be used when other methods have failed (as they do in up to 50% of cases of persistent AF). Although this procedure results in a regular (paced) heart rhythm it does not prevent the atria from fibrillating and therefore long-term warfarin anticoagulation may still be required.

The Maze procedure, first performed in 1987, is an effective invasive surgical treatment that is designed to create electrical blocks or barriers in the atria of the heart, forcing electrical impulses that stimulate the heartbeat to travel down to the ventricles. The idea is to force abnormal electrical signals to move along one, uniform path to the lower chambers of the heart (ventricles), thus restoring the normal heart rhythm.Northwestern Surgery for Atrial Fibrillation. Atrial Fibrillation Surgery People with AF often undergo cardiac surgery for other underlying reasons and are frequently offered concomitant AF surgery to reduce the frequency of short- and long-term AF. Concomitant AF surgery is more likely to lead to the person being free from atrial fibrillation and off medications three months after surgery, but these same people are more likely to need a pacemaker following the procedure.

New St. Michael's Cave, also known as Lower St. Michael's Cave, is a cave system in the British Overseas Territory of Gibraltar. Unlike its namesake, St. Michael's Cave (proper), which has been known for over 2,000 years, this cave was discovered as recently as World War II. The cave was accidentally discovered during World War II, when in 1942 the Royal Engineers were blasting inside the Rock of Gibraltar so as to create an alternate entrance to the lower chambers of St. Michael's Cave, which had been prepared as an emergency hospital. The first sign was when their tunnelling appeared to create no rubble as it had fallen through the newly created opening into this previously undiscovered cave which may have remained sealed for some 20,000 years. The cave's chambers include examples of almost all known cave formations, including a lake nearly long containing an estimated of crystal-clear water.

Conservative Council was the name of the Dominican upper chamber between November 1844 and February 1854. The Dominican Constitution of 1844 foresaw the existence of two chambers in the national congress: the Conservative Council and the Tribune, upper and lower chambers which in other Dominican constitutions of the nineteenth and twentieth centuries received the name of Senate and Chamber of Deputies or Representatives; With that it was intended to conform a system according to the model of the United States Congress, which would correspond to the Conservative Council a similar function to the Senate in the United States. The designation of the president of the Conservative Council corresponded to the same chamber, of a triad voted by the members. The sessions of the Conservative Council were held the current Borgellá Palace in the Plaza Colon of the Colonial City of Santo Domingo, in front of the first town hall in the Palace Hall.
