- 1. ECG
- 20. In ARVC, there is T inversion and delayed ventricular activation manifest as Epsilon waves (arrows). Panel B shows ST elevation in V1 and V2 typical of the Brugada syndrome.
- 21. • 12-lead ECG showing 2:1 AV block (P waves marked by blue arrows) with heart rate of 40 bpm and QT interval of 680 ms and corrected QT of 550 ms.
- 22. The bottom panel shows a telemetry rhythm strip with periods of self-limiting torsades des pointes polymorphic VT. Following a normally conducted sinus beat, a premature ventricular contraction (PVC) causes a compensatory pause leading to along RR interval. A PVC after the next sinus beat initiates VT. This is the classic “pause dependent” mode of initiation of torsades des pointes VT with long–short intervals. VT, ventricular tachycardia.
