Highlights a case of ventricular tachycardia with electrical alternans caused by digitalis toxicity.
QRS alternans in VT may signal digitalis toxicity; single case leaves open diagnostic utility.
T H E electrocardiographic picture of ventricular tachycardia is usually quite characteristic, and although the rhythm is as a rule slightly irregular, the ven-tricular complexes are quite uniform in appearance. Regular alternation in the direction of the QRS complexes during ventricular tachycardia has been reported by various authors, and, in the majority of cases digitalis intoxication has been responsible for the tachycardia.1"4 We should like to present the following case report and electrocardiogram demonstrating alternation in the amplitude of the
