  Question Top


Interpret the electrocardiogram (ECG) findings.


  Clinical Details Top


A 55-year-old, nondiabetic, nonhypertensive female presented with history of recurrent syncope since last 5 years. Her ECG is shown in [Figure 1]. Her ECG showed normal left ventricular (LV) function (LV ejection fraction = 55%). She underwent 24 h Holter monitoring which showed no significant tachy or bradycardia. Coronary angiography was normal. After 1 month, she presented with recurrent palpitation and one episode of syncope.

ECG is suggestive of sinus bradycardia with long QT and QTc. T-wave is low-amplitude and bifid (Arrowed) [Figure 2]. Prolong QTc with low-amplitude and bifid T-wave may occur in long QT syndrome Type 2 (LQTS 2). Sinus bradycardia may be associated with LQTS. ECG of the same patient as shown in [Figure 3] showed recurrent episodes of polymorphic ventricular tachycardia preceded by long coupled premature ventricular ectopics (Arrowed)..
