These three panels are continuous and represent the testing of a Medronic model 7219 defibrillator. The channels are a surface EKG lead, a ventricular intra-cardiac recording and a marker channel from the device.
The first panel shows rapid paced ventricular beats followed by a low energy shock which induces VF. The shock is not on the T wave.
