[Polymorphic ventricular tachycardia with a short coupling interval in a patient with normal heart--a case report].
We describe a case of a 59-year-old female with paroxysmal atrial fibrillation and arterial hypertension who had syncopal attacks due to polymorphic ventricular tachycardia (PMVT) with a short coupling interval of an initiating beat (280 msec). We excluded structural heart disease. In the resting ECG the QTc interval was 420 msec. During Holter monitoring a slight changes of the ST-T segment in V1 were observed (from positive T wave with ST elevation of 1 mm to flat or negative T wave without ST elevation). Additionally, after PMVT a large U-wave (4 mm of amplitude) with the QTU interval of 600 msec and QTUc interval of 662 msec were observed. The U wave disappeared 9 minutes afterwards. The ajmaline test was positive for the Brugada syndrome. The patient received ICD and sotalol, and during 6-month follow-up she remains asymptomatic.
