Ventricular fibrillation EKG examples
Shown below is an EKG image of ventricular fibrillation showing irregular heart rhythm, heart rate of more than 300 per minute, QRS duration unrecognizable and absent P waves.

Shown below is an example of sinus rhythm converting into ventricular fibrillation wave pattern of irregular rhythm and unrecognizable QRS and P waves.
Shown below 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.
The second panel below shows the VF, note the readings of the marker channel.
Shown below last panel shows the termination of the VF with a 20 joule shock and then ventricular pacing. Note the ST elevation of the paced beats.
