A recipient of a dual-chamber pacing system, with a bipolar endocardial lead screwed into the right ventricular outflow tract (RVOT), developed intercostal muscle twitching. No lead perforation was identified. This observation suggests that meticulous attention should be paid to this potential complication when choosing the RVOT as a site of permanent endocardial pacing.
