Treatment of severe left ventricular dysfunction with calcium chloride in patients receiving verapamil

This report describes two patients who received verapamil because of supraventricular arrhythmias. The patients both developed severe hypotension and signs of left ventricular compromise. The hypotension and left ventricular compromise were promptly reversed by administration of intravenous calcium chloride. The dramatic improvement was documented clinically and in one case by two-dimensional echocardiography.
