Ventricular and Supraventricular Ectopy in Subjects With Early Repolarization

Abstract

Early repolarization (ER) is a common electrocardiographic (ECG) finding that is associated with an increased risk of idiopathic ventricular fibrillation and sudden cardiac death. This study investigated whether the presence of ER is a predictor of ventricular and supraventricular ectopy as a marker for electrical instability. Standard 12-lead electrocardiograms of the first follow-up in the population-based Study of Health in Pomerania (SHIP-1) (n = 3,300, age 20 to 79 years) were analyzed to identify subjects with an ER pattern. Ventricular and supraventricular ectopy was assessed via portable tele-ECG cards recording 2 electrocardiograms daily over the course of 4 weeks. Data of 1,630 subjects (n = 83,833 ECG card recordings, average 51.4 per subject) were analyzed for ventricular and supraventricular ectopy using a standardized automated algorithm. Associations of ER and several forms of arrhythmias were assessed using a 2-sided Fisher's exact test or t test, where appropriate. Overall, prevalence of ER in the SHIP-1 population was 4.8%. Presence of ER was not associated with the occurrence of ventricular and supraventricular arrhythmias (p ≥0.05 for all analyses). Furthermore, subgroup analyzes for ER localization (inferio...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.

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.

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.

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.

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.
