Efficacy of intravenous amiodarone as short-term treatment for refractory ventricular tachycardia.

abstract：BACKGROUND:Previous studies have suggested that thrombolysis is used less often in blacks than in whites. However, whether the greater prevalence of contraindications or less specific electrocardiographic manifestations of myocardial infarction (MI) account for this difference is unclear. METHODS AND RESULTS:We studie...
