Cross‐Stimulation: A Rare Complication of Chronic Epicardial Leads

Abstract

Cross-stimulation is a rare phenomenon that occurs during dual-chamber pacing when the pacing stimulus to one chamber results in the inadvertent capture of the other. Most cases are attributable to intrinsic design features of particular device models or lead malpositioning, and only occur early postimplantation with subsequent spontaneous resolution. We report a case of cross-stimulation occurring in a patient with chronic epicardial leads without loss of lead integrity.

A rare case of epicardial left ventricular sutureless screw-in lead placement causing left anterior descending artery stenosis

“…These include pericardial tamponade, pericardial constriction, recurrent pericarditis, infection, and cross-stimulation 8, 9, 10, 11, 12. To our knowledge, this is the first case report of an epicardial LV lead placement with development of subjacent LAD stenosis.…”
