Abstract

The relationship of epicardial fat and cardiac arrhythmias has been described in many studies. The association of the amounts of epicardial fat and the characteristics of electrocardiogram (ECG) remains unclear. The purpose of this study was to elucidate the association between the amounts of epicardial fat and the characteristics of ECG. A total of 100 consecutive patients who received multi-detector computer tomography (MDCT) were enrolled. The amounts of epicardial fat, including total heart, total atria, total ventricles, right atrium (RA), right ventricle (RV), left atrium (LA), and left ventricle (LV) regions, were measured. The PR interval in lead II, the P wave duration in lead I, the characteristics of inter-atrial conduction block manifested in ECG, the corrected QT interval (QTc) and the QT dispersion of a 12‑lead ECG were measured manually by a computer caliper. The PR interval was correlated with the amounts of epicardial fat including total heart, total atria, total ventricles, RA, RV, LA, and LV (R = 0.295, p = 0.003; R = 0.379, p < 0.001; R = 0.284, p = 0.003; R = 0.415, p < 0.001; R = 0.287, p < 0.001; R = 0.33, p < 0.001; R = 0.244, p = 0.014). The P wave duration of lead I was also correlated with the amounts...Continue Reading

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.

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.
