WebElectrical interference is a problem when devices sense external signals as intrinsic cardiac signals, resulting in inhibition of pacing and possibly inappropriate defibrillation. Magnets flick a switch in pacemakers and defibrillators, which can result in asynchronous pacing or inactivation of defibrillation. WebThe current dogma about the heartbeat origin is based on “the pacemaker cell,” a specialized cell residing in the sinoatrial node (SAN) that exhibits spontaneous diastolic depolarization triggering rhythmic ... Cardiac impulse is an emergent property of the SAN cellular network and can be initiated by cells lacking intrinsic automaticity.
