Key result
Pectoral muscle contraction was shown to inhibit demand pacemakers in 24% of tested patients, potentially leading to cerebral ischemic episodes.
Why the study?

Myopotential inhibition warrants consideration in symptomatic pacemaker patients; this case report leaves open true incidence and preventive strategies.

Can skeletal muscle potentials from pectoral muscle contraction inhibit demand pacemakers?
Myopotentials from pectoral muscle contraction can inhibit demand pacemakers, potentially leading to cerebral ischemic episodes.
D. A. Winter (1973) conducted an observational in Patients with demand pacemakers. Pectoral muscle contraction (myopotentials) was evaluated on Vulnerability to pacemaker inhibition by pectoral muscle contraction. Pectoral muscle contraction was shown to inhibit demand pacemakers in 24% of tested patients, potentially leading to cerebral ischemic episodes.
