摘要: The effects of injected 50 Hz alternating current on the function cardiac pacemakers has been observed in 18 patients with implanted unipolar VVI units. Current, range 0-600 microA was applied via electrodes attached to patients' upper body and feet fed from a specially designed injection unit at bedside. Most reverted interference mode 29-250 microA. At levels just below reversion all units developed irregular inappropriate pacing. This level pacemaker dependent varied 27-246 total depended location injecting posture. sensitivity increased by deep inspiration. Temporary pacing catheters fitted an additional ten were used monitor voltage which would be sensed unit. similarly patient posture respiration. Current proved safe, controllable reproducible method testing external interference.
