Fig. 4From: High-energy external defibrillation and transcutaneous pacing during MRI: feasibility and safetyECG before and after Defibrillation during Active Scanning. ECG in lead V1 before defibrillation (a) and after defibrillation (b-d) during MRI scanning (balanced steady-state free precession sequence; bSSFP) in one of the animals (pig #6). Inset (e) shows detailed waveform morphology. Defibrillation was performed at time = 0Back to article page
