ELECTROMAGNETIC-INTERFERENCE FROM A MUSCLE STIMULATION DEVICE CAUSINGDISCHARGE OF AN IMPLANTABLE CARDIOVERTER-DEFIBRILLATOR - EPICARDIAL BIPOLAR AND ENDOCARDIAL BIPOLAR SENSING CIRCUITS ARE COMPARED

This case report is about two patients with live different types of IC Ds who underwent electrical muscle stimulation (EMS) therapy. In one p atient with an ICD that has epicardial screw-in bipolar sensing leads, electromagnetic interference (EMI) from the EMS device caused the del ivery of an inappropriate ICD discharge. In a second patient with an I CD with endocardial true bipolar sensing, there was no evidence of EMI during the EMS therapy despite all of our attempts to reproduce if. T he sensing circuits in the two different ICDs are compared.
