Electrophysiologic mapping to determine the mechanism of experimental ventricular tachycardia initiated by premature impulses. Experimental approach and initial results demonstrating reentrant excitation

The American Journal of Cardiology

Abstract

Epicardial activation patterns were determined during repetitive responses and nonsustained and sustained ventricular tachycardias induced by premature impulses in infarcted canine hearts. A multiplexing system enabled recordings to be obtained from up to 192 electrodes simultaneously either from the entire epicardial surface with a sock electrode array or only from the sheet of epicardial muscle that survives over the infarcts, with a plaque electrode array. In hearts with an infarct caused by permanent occlusion of the left anterior descending coronary artery, the earliest epicardial excitation during nonsustained tachycardias occurred on the anterior left ventricle at the border of the infarcted region and in epicardial muscle surviving over the infarcted region. Circuitous conduction patterns leading to reentry occurred in the epicardial muscle over the infarct and probably caused the arrhythmias. During sustained tachycardia in hearts with an infarct caused either by permanent or temporary occlusion of the left anterior descending coronary artery, the earliest epicardial excitation also occurred at the border of the infarcted region, but there was no evidence of reentry in the surviving epicardial muscle.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

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.

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system here.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
