WebBackground: Strength-duration curves for permanent His bundle (HB) pacing are potentially important for pacemaker programming. Objectives: We aimed to calculate strength-duration curves and chronaxies of the HB and of the adjacent right ventricular (RV) working myocardium and to analyze zones of selective HB capture and battery current drain … WebClassically, to electrically excite C-nociceptors, rectangular pulses are used with a duration close to the estimated chronaxie of C-fibres (about 2 ms). Recent results using slow …
WebA comparison of chronaxies for ventricular fibrillation induction, defibrillation, and cardiac stimulation: unexpected findings and their implications It may be reasonable to study whether LEC pulses from 0.25 ms to 0.30 ms in duration and up to 250 V in amplitude would increase therapeutic yield in VT termination without VF induction in humans. Webstructures have different chronaxies, stimulus pulse duration is an important control parameter for selec-tive stimulation. For example, the shorter chronaxy of myelinated motor neurons compared with that of unmyelinated fibers of the myocardium allows safe stimulation with short pulses during artificial respira-tion.
