Supernormal excitability and conduction

Cardiology Clinics
M B RosenbaumR A Sánchez

Abstract

The authors examine circumstances in which supernormality causes specific electrocardiographic events. True supernormal conduction is much more common than previously thought. A complete scanning of the cardiac cycle in patients with phase 3 BBB or with second-degree or advanced infranodal AV block would reveal that a much larger number of cases of supernormal conduction would be uncovered.

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.

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.
