Transvenous cardiac implantable electronic devices withstand contact sports in an experimental model.

ABSTRACT:

Aims

Cardiac implantable electronic device (CIED) patients are routinely advised against physical activity with a risk of collision because of expected damage to the implanted device. However, no data support this practice.

Methods and results

Sixteen CIED systems (six pacemakers, six ICD, four CRT-D) from all manufacturers were implanted subcutaneously in a porcine thorax and increasing weights were dropped on the experimental setting. Cardiac implantable electronic device function was analysed in an interactive heart simulator (InterSim III, IB Lang). In a second experiment, forces resulting in irreversible damage were investigated in explanted CIED. No signs of malfunction were seen in any CIED after a total of 256 impacts up to 2000 N. Forces exceeding 1500 N reproducibl
