Six instances of sudden death were recorded by Holter monitoring, which showed ventricular fibrillation in five and a bradyarrhythmia in one. Complex ventricular ectopic activity preceded cardiac arrest in five patients, including the one with the bradyarrhythmic arrest. Two patients with chronic bifascicular block arrested as a result of ventricular fibrillation. Fifteen cases reports from the literature are reviewed. The composite profile includes advanced myocardial disease (present in all cases), complex ventricular ectopic activity, R-on-T initiation of the terminal rhythm except in patients with prolonged QT interval, and variations in cycle length preceeding the onset of ventricular tachycardia or fibrillation. The role of supraventricular mechanisms in sudden death is uncertain.

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.

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.
Bradyarrhythmias are slow heart rates. Symptoms may include syncope, dizziness, fatigure, shortness of breath, and chest pains. Find the latest research on bradyarrhythmias here.
Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
