Electrocardiographic markers of arrhythmogenic risk in patients with isolated coronary artery ectasia.

ABSTRACT:

Background

Coronary artery ectasia (CAE) is an uncommon finding with potential clinical implications, including arrhythmogenic risk. Electrocardiographic parameters such as QT dispersion (QTd) and P wave dispersion (PWD) have been proposed as non-invasive predictors of electrical instability. This study aimed to compare ECG findings, between patients with isolated CAE and those with normal coronary arteries.

Methods

In this case-control study, 23 patients with isolated CAE (Group 1) and 26 patients with angiographically normal coronary arteries (Group 2) were enrolled. Groups were matched for age, gender, cardiovascular risk factors, and ejection fraction. Patients with conditions or medications affecting conduction were excluded. ECG parameters were compared using Chi-squar
