From: Knock-in Kcnh2 rabbit model of long QT syndrome type-2, epilepsy, and sudden death
Sudden Death Case-1 exhibiting epileptiform discharges and extreme QT prolongation. Black arrow indicates a region where T and P waves of adjacent beats are temporally separated. Green arrow indicates a region where, due to extreme QT prolongation, the P wave is encapsulated by the T wave of a previous beat, causing an absence of the T-P interval. EEG scale bar indicates 140µV amplitude and 2 s; inset: ECG scale bar indicates 2000µV amplitude and 1 s
