To shorten the delay in the onset of antiarrhythmic effect when using amiodarone for the conversion of refractory atrial tachyarrhythmias to sinus rhythm, 19 patients were given oral amiodarone according to a high-dose loading protocol. In 18 of 19 patients (95%), sinus rhythm was restored 36 hours (range, 0 to 96 hours) after starting amiodarone. The conversion occurred as a result of amiodarone therapy alone within 48 hours in 12 patients (63%), and by amiodarone therapy plus electrical cardioversion at 48 to 96 hours in six patients (32%). Minor side effects were noted in eight patients (42%). No major side effects were encountered. The length of hospital stay after initiating amiodarone therapy was 3.6 days (range, 2 to 5 days). High-dose oral amiodarone loading is a safe and effective method for the rapid conversion of atrial tachyarrhythmias to sinus rhythm.

D000638	Amiodarone	An antianginal and class III antiarrhythmic drug. It increases the duration of ventricular and atrial muscle action by inhibiting POTASSIUM CHANNELS and VOLTAGE-GATED SODIUM CHANNELS. There is a resulting decrease in heart rate and in vascular resistance.

D001145	Arrhythmias, Cardiac	Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction.

D001281	Atrial Fibrillation	Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.
