Introduction: Transvenous insertion of endocardial leads for permanent pacing is often accompanied by minor myocardial damage, detected thanks to the high sensitivity of cardiac troponins. It is unknown whether higher troponin levels, commensurate with more severe myocardial damage, can be encountered after implantation procedures.
Methods: Over a 3-year period, 283 patients underwent an implantation of a full antibradycardia pacemaker system (pulse generator plus leads).
