Amiodarone-induced torsade de pointes--five case reports

Kardiologia polska
Piotr Kukla, Teresa Słowiak-Lewińska

Abstract

Five patients with amiodarone-induced QT prolongation and torsade de pointes are described. Hypokalemia was present in three patients, marked bradycardia - in two, and T-wave alternans - also in two patients. Patients with negative T waves in precordial leads were at higher risk of ventricular fibrillation than the patients with positive T waves. Beta-blocker, lidocaine and, in two patients, tosylate bretylate were effective. All patients survived to hospital discharge, however, one patient died four months later.

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.

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.

Bradyarrhythmias

Bradyarrhythmias are slow heart rates. Symptoms may include syncope, dizziness, fatigure, shortness of breath, and chest pains. Find the latest research on bradyarrhythmias here.
