Vollbildansicht	ECG leads Abbildung 1: Left: Standard precordial ECG leads V1–V6 (10 mV amplitude, 50 mm/s paper speed) of case no.1 with prolonged QRS duration in right precordial leads, small epsilon potential in V2 and saddle-back ST-segment elevation in V2. QTc interval 340 ms (NOTICE: horizontal line marking 1000 ms); right: precordial leads of case no. 1 after ajmaline administration with coved-type ST elevation in V1 and V2 and right bundle branch block configuration. Keywords: ECG, Kardiologie


Vollbildansicht	ECG leads Abbildung 2: Left: Standard precordial ECG leads V1–V6 (amplitude 10 mV, paper speed 50 mm/s) of case no. 2 with prolonged QRS duration in right precordial leads, small epsilon potential in V1 and V2 and prominent U waves in V2 and V3. QTc 340 ms (NOTICE: horizontal line marking 1000 ms); right: precordial ECG leads of case no. 2 after ajmaline administration with coved-type ST elevation in V1 and right bundle branch block configuration. Keywords: ECG, Kardiologie


Vollbildansicht	ECG leads Abbildung 3: Left: Standard precordial ECG leads (10mV amplitude, paper speed 50 mm/s) of case no. 3 with prolonged QRS duration in right precordial leads and T wave inversions in V1 and V2. QTc interval 360 ms (NOTICE: horizontal line marking 1000 ms); right: precordial leads of case no. 3 after ajmaline administration with significant coved-type ST elevation in V1 and right bundle branch block.
