Product Information

The normal resting heart rate is called the sinus rhythm, created and sustained by the sinoatrial node, a group of pacemaking cells found in the wall of the right atrium. Cells in the sinoatrial node do this by creating an action potential. The cardiac action potential is created by the movement of specific electrolytes into and out of the pacemaker cells. The action potential then spreads to nearby cells. [49] Neubauer, Stefan (15 March 2007). "The Failing Heart – An Engine Out of Fuel". New England Journal of Medicine. 356 (11): 1140–1151. doi: 10.1056/NEJMra063052. PMID 17360992. S2CID 1481349. The heart is the first functional organ to develop and starts to beat and pump blood at about three weeks into embryogenesis. This early start is crucial for subsequent embryonic and prenatal development. stroke: A stroke can happen when part of the brain doesn't get enough blood due to a clot or a burst blood vessel.

arrhythmia (say: uh -RITH-mee-uh) : An arrhythmia is an abnormal heartbeat usually caused by an electrical "short circuit" in the heart. It can cause the heart to pump too fast, too slow, or irregularly, which may lead to shortness of breath, dizziness, and chest pain.

But the things which proceed out of the mouth, come forth from the heart, and those things defile a man.

In the heart of lungfish, the septum extends partway into the ventricle. This allows for some degree of separation between the de-oxygenated bloodstream destined for the lungs and the oxygenated stream that is delivered to the rest of the body. The absence of such a division in living amphibian species may be partly due to the amount of respiration that occurs through the skin; thus, the blood returned to the heart through the venae cavae is already partially oxygenated. As a result, there may be less need for a finer division between the two bloodstreams than in lungfish or other tetrapods. Nonetheless, in at least some species of amphibian, the spongy nature of the ventricle does seem to maintain more of a separation between the bloodstreams. Also, the original valves of the conus arteriosus have been replaced by a spiral valve that divides it into two parallel parts, thereby helping to keep the two bloodstreams separate.

Early repolarisation syndrome - common in younger and active people, especially men, because it is affected by higher testosterone levels, which cause increased potassium currents, which further causes an elevation of the J-point on the EKG. In very rare cases, it can cause ventricular fibrillation and death. [75]Cooper, David K. C. (1 January 2012). "A Brief History of Cross-Species Organ Transplantation".
