WebOct 1, 2016 · A pacemaker is a device that provides electrical stimuli to maintain or restore a normal heartbeat. Pacing systems are made of 2 implantable cardiac components (the pacemaker pulse generator and the intracardiac leads), and can be interrogated by using a wireless, telemetered, external programming device.1 Pacemakers can be dual- or single … WebApr 12, 2024 · There will be 25 drug-refractory epilepsy (DRE) patients in this study. Device: transcranial magnetic stimulation. The stimulation intensity will be 80% resting motor threshold (RMT). The theta burst stimulation (cTBS) with a frequency at 50Hz, repeated at 5Hz, are delivered in a duration of 33.2s with the number of stimulation pulses of 600.
WebIn DDDR mode, the pacemaker follows the fastest rate, being either the intrinsic atrial rate or the rate indicated by the sensor. The maximal tracking rate and the maximal sensor rate are to be programmed seperately. … WebThe amplitude of the atrial stimulus is decremented in steps of 0.25 V until loss of capture with a 5-V backup pulse delivered 40 msec after the test stimulus. The amplitude is then …
