Abstract

Sudden cardiac death caused by ischemic ventricular fibrillation (VF) associated with ST elevation myocardial infarction (STEMI) is one of the most frequent causes of death. We hypothesized that electrocardiographic (ECG) characteristics differ between STEMI patients with and without ischemic VF. Fifty-five first STEMI patients with at least one 12-lead ECG recorded before ischemic VF were compared with 110 first STEMI patients without ischemic VF. Patients with bundle branch blocks or high-degree atrioventricular blocks with escape rhythms were not included. ECG measurements were performed manually after scanning the ECG with the most prominent ST deviation into a software environment and magnifying it 4 times. Mean age was 57 +/- 12 years, and 126 patients were male. No differences were present between the VF and control group regarding baseline, enzymatic, and angiographic data. In left circumflex artery and right coronary artery myocardial infarction, a longer QRS interval (109 +/- 23 ms vs. 91 +/- 16 ms, P = .02 and 107 +/- 24 ms vs. 93 +/- 19, P = .02) was present. In the latter the PR interval (211 +/- 64 ms vs. 160 +/- 36 ms, P <.001) and ST deviation score (3.6 +/- 1.0 mV vs. 1.7 +/- 1.5 mV, P <.001) were also increase...Continue Reading

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.

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.

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.
