Effects of Induction Ovens and Cooktops on St. Jude Medical Implantable Cardiac Rhythm Devices

Background

Induction ovens and cooktops use induction heating to directly heat the cooking pot. An alternating electric current flows through a copper wire coil below the cooking pot, which produces an oscillating magnetic field. This magnetic field induces an electric current in the pot, which produces resistive heating to heat the food.

Potential effects

Under normal operating conditions, induction ovens and cooktops should not cause interference with the performance of St. Jude Medical pacemakers and implantable cardioverter defibrillators (ICDs). A search of literature showed no reports of any significant interference in pacemakers and ICDs.1, 2 In an isolated case asynchronous pacing was seen in a unipolar pacemaker.

A summary of potential effects is provided in the table below and is based on device testing at St. Jude Medical, clinical experience and/or a review of the scientific literature.

Potential Effect Estimated Frequency
  Pacemakers ICDs
Asynchronous pacing Rare N/A

Recommendations

St. Jude Medical does not anticipate any interference between induction ovens or cooktops and St. Jude Medical cardiac implants under normal operating conditions. Additionally, patients have used induction ovens and cooktops with no reported adverse effects.
