Myopotential Inhibition of Demand Pacemakers
AUTOR(ES)
Lazar, Anthony V.
RESUMO
Two patients are described in whom skeletal muscle potentials originating in the shoulder girdle muscles during isometric movement suppressed the discharge of a ventricular demand unipolar pacemaker, resulting in syncope. Converting the pulse generator into a fixed-rate mode with the magnet prevented the inhibition. Improved filters or wider use of bipolar electrodes should prevent this form of interference.
