Is a patient with a cardiac pacemaker a contraindication for diathermy?

Is a patient with a cardiac pacemaker a contraindication for diathermy?

• A. Yes
• B. No
• C. Only with MRI
• D. Only if device is external

Answer: (A)

Diathermy energy can interfere with implanted electronic devices like pacemakers. The electromagnetic field and heating effects from diathermy can cause the pacemaker to malfunction, such as inappropriate sensing or inhibition of pacing, or can cause heating at the lead tips and surrounding tissue. This combination of potential device interference and tissue heating makes diathermy unsafe for patients with a cardiac pacemaker, so it is considered a contraindication. If energy-based therapy is ever considered, it requires careful coordination with the cardiology team and device manufacturer and is generally avoided in favor of safer alternatives.
