Abstract
There is evidence that some powered muscle stimulators can affect cardiac demand pacemakers, although devices vary enormously in terms of the intensity, frequency, and duration of stimuli. Regulatory authorities require that specialist medical opinion be obtained before using a stimulator on a patient with an implanted device. However, no explicit criteria are specified. This study aims to determine if there are any detectable interactions between a small, wearable stimulator which activates the muscle pumps of the leg by delivering a single momentary pulse at a frequency of 1Hz. 28 patients with pacemakers (single chamber, dual chamber, or bi-ventricular) were given stimulation. The pacemaker marker channel was recorded, and the electrogram examined to detect any sensed signal from the stimulator. In total, 2372 energy pulses were delivered by the stimulators. None of these were sensed by the pacemaker. This appears to show that there is no appreciable interaction between this type of stimulator and cardiac demand pacemakersCopyright The copyright holder for this preprint is the author/funder, who has granted medRxiv a license to display the preprint in perpetuity.
