This study is designed to compare a new prototype surgical magnetic drape made with bottom-isolated ferrite magnets to 4 commercially available surgical magnetic drapes.
Magnetic fields may potentially interfere with the function of cardiovascular implantable electronic devices. Sterile magnetic drapes used to hold surgical instruments are often placed on the patient's thorax, and they are likely to interfere with the function of these devices. This study compares the magnetic interference of a new prototype surgical magnetic drape made with bottom-isolated ferrite magnets to the Covidien magnetic drape and 3 other commercially available surgical magnetic drapes.

New prototype surgical magnetic drape made with bottom-isolated ferrite magnets applied to the patient's thorax
Green Covidien Magnetic Drape applied to the patient's thorax
Jaa-Cell Medic Reusable Magnetic Pad applied to the patient's thorax
Percentage of magnetic interference
Percentage of patients experiencing magnetic interference with the application of each surgical magnetic drape. Magnetic interference defined as a cardiac rhythm change to asynchronous and identical to that produced by a round magnet rhythm over the pacemaker.
Time frame: Within 2 minutes after placement of surgical magnetic drape to the patient's chest
