Is there risk going in the sun for an extended period of time with an implantable cardioverter defibrillator?

Manufacturer's literature and "training" have not indicated sun exposure is an issue on my defibrillator, Boston Scientific.

However, some of the drugs I take (Lasix) cautions against exposure to sunlight.

If you get badly burnt, it really impacts the body and no doubt effects the heart. Take precautions.

No. Solar radiation and increased temperature should not in any way affect the operation of an ICD.

Good luck
