Survival to leave hospital from ventricular fibrillation

American Heart Journal

Abstract

In 125 consecutive patients with 173 arrests due to ventricular fibrillation, 53 survived to leave hospital. At the initial arrest and using univariate analysis, those who had primary ventricular fibrillation, had ventricular fibrillation less than 24 hours from the onset of symptoms, received the first DC shock less than 1 minute after the onset of ventricular fibrillation, who required less than 4 shocks to terminate the ventricular fibrillation, whose first established rhythm within the first minute of correction of ventricular fibrillation was atrial fibrillation, sinus rhythm or paced rhythm, or who were not receiving prior antiarrhythmic agents had a significantly improved survival to leave hospital (p less than 0.05). To predict survival to leave hospital using discriminant function analysis, the most significant factors ranking in order of importance at the time of the initial arrest were: less than or equal to 5 shocks to correct ventricular fibrillation, no prior antiarrhythmic therapy, primary ventricular fibrillation, and time from onset of ventricular fibrillation to first shock less than 1 minute. For the last arrest, the most significant factors were: no prior cardiac arrest, less than or equal to 5 shocks to cor...Continue Reading

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.

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.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. 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.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.
