Fig. 5From: High-energy external defibrillation and transcutaneous pacing during MRI: feasibility and safetyCardiac Pacing with Ventricular Capture. Sample ECG tracing during transcutaneous, constant-rate (non-demand) pacing at 60 bpm with ventricular capture in the magnet bore in one of the animals (pig #4) using monophasic, 20-ms, 150 mA pulses with rise/fall times ≤1 msec. The pacing was applied in a subset of two animals and produced reliable ventricular capture in both animalsBack to article page
