Abstract

Acute intoxications with the antiarrhythmic drug disopyramide (Norpace) are often life-threatening. After an almost asymptomatic interval of 1 to 4 hours, cardiogenic shock of sudden onset occurs. The usual methods of cardiac resuscitation such as adrenaline and antiarrhythmic drugs should not be used, and transvenous pacemakers often prove ineffective. To lower the high rate of mortality, early appropriate monitoring and facilities for rapid intervention are necessary. Isoprenaline is the most suitable positive inotropic and chronotropic drug. Hemoperfusion with Amberlite XAD 14 is effective but not always needed.

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.

Cardiogenic Shock

Cardiogenic shock is a devastating consequence of acute myocardial infarction and is associated with an extremely high mortality. Here is the latest research.
