Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical Trial
Intravenous administration of diltiazem in the treatment of supraventricular tachyarrhythmias.
The aim of the study was to investigate the efficacy of diltiazem bolus intravenous administration, compared to disopyramide, in the treatment of various types of paroxysmal supraventricular tachyarrhythmias. ⋯ Diltiazem administration is extremely effective in conversion of paroxysmal atrial tachycardia to sinus rhythm. In addition it retards ventricular response in patients with atrial fibrillation and fluttering. Compared to disopyramide these effects of diltiazem are more pronounced and clinically pertinent.

A terminally ill patient with cardiac tamponade secondary to metastatic breast cancer was successfully treated by percutaneous balloon pericardiotomy. The procedure was performed through subxiphoid approach under local anaesthesia and its beneficial effect was maintained until the patient's death from her primary disease. A second, 86-year-old, debilitated patient and a third 52-year-old patient were managed likewise and both left hospital relieved from recurrent severe pericardial effusions. The later two patients have shown no signs of recurrence for fifteen and twelve months respectively.
