Epirubicin-induced QT prolongation monomorphic ventricular tachycardia and response to beta blockade in long QT syndrome type 2

摘要

Example of the rhythm after start of the cytostatic pulse 1. Telemetry recording after the epirubicin infusion under treatment with metoprolol (paper speed 25 mm/s). The rhythm at this time consisted of runs of nonsustained monomorphic wide-QRS tachycardia with heart rate 125 beats per minute, separated by a few normal complexes. The patient complained about palpitations but was otherwise unaffected.
