Clinical significance of an equivocal signal-averaged electrocardiogram

The American Journal of Cardiology
S D NelsonS F Schaal

Abstract

Patients with an equivocal signal averaged electrocardiogram (SAECG) had less heart disease and better prognosis than patients with overtly abnormal SAECGs. An equivocal SAECG should not prompt further invasive diagnostic testing for ventricular tachycardia unless other clinical risk factors are present.

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.

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.
