Abstract

It was found that following occlusion of the coronary artery in dogs, the rate of increase in K+ concentration in blood plasma draining directly from the focus of ischemia is greater in cases complicated by ventricular fibrillation. Fibrillation always occurs against the background of a decrease in pH and an increase in the K+ level in blood plasma draining from the focus of ischemia. It is suggested that inhibition of the development of disorders of acid-base and ion equilibrium in the myocardium would be an effective means of preventing ventricular fibrillation in the acute stage of myocardial infarction.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
