Can Someone with a Pacemaker Wear a Heated Vest?
Short answer: Often yes—but with precautions and only after checking your specific device maker’s guidance and your clinician’s advice. The main issues are electromagnetic interference (EMI) and magnets/electronics placed too close to the implant. The good news: modern pacemakers are designed to tolerate most everyday electronics when used correctly.
Why Do Heated Vests Raise Questions
Heated vests use a rechargeable battery to power thin heating elements sewn into the garment. That setup can create small electromagnetic fields and sometimes includes magnets in closures or battery packs—both of which matter for pacemakers if placed very close to the device. Regulators and manufacturers generally advise keeping consumer electronics and magnets at least 6 inches (15 cm) from the implant site.
What Leading Sources Say
-
Cardiac-device manufacturers (Abbott, Boston Scientific, Medtronic): Most household items are safe when used as intended and kept at recommended distances. Their public EMI guides are good “first checks.” Electric heating products (e.g., electric blankets) are commonly listed as safe under normal use, with standard distance/placement cautions.
-
Regulators (FDA): Keep consumer devices that contain magnets or wireless transmitters at least 6 inches (15 cm) from the implant. Don’t let magnetic accessories rest over the pacemaker.
-
Heart-health organizations: Many heating devices can be used if you follow manufacturer guidance or ask your pacing clinic.
-
Edge cases: Rare reports exist of interference from an electric blanket when conditions weren’t ideal—use this as a reminder to follow distance and placement rules.
Practical Safety Checklist (Use This Before Wearing a Heated Vest)
-
Ask your clinician/pacing clinic and check your device maker’s EMI page for the latest guidance specific to your model.
-
Mind the distance: Keep the battery pack, wiring, and any magnets ≥ 6 inches (15 cm) from your implant (usually the upper chest). Don’t store the battery in a chest pocket over the device.
-
Placement tips:
-
Wear the battery on the hip or the side opposite your implant.
-
Route cables away from the implant area; avoid coiling wire over the pacemaker pocket. (General EMI minimization principle.)
-
Avoid strong magnets: Skip garments or accessories with magnetic closures over the implant site. Keep phones, earbuds cases, and other magnetic items away from the device area.
-
Use the manufacturer’s battery/charger: Third-party batteries may lack safeguards (over-temp/over-current) and are more likely to include stronger magnets or electrical noise.
-
Start low, monitor, and stop if you feel off: Begin on the lowest heat setting. If you notice dizziness, palpitations, or unusual symptoms, turn the vest off and move the battery farther away. Contact your clinic if symptoms persist. (Conservative medical safety practice.)
-
Inspect for damage: Frayed cables or damaged connectors can increase EMI and safety risks—replace the garment or battery if damaged. (General manufacturer guidance principle.)
FAQs
Is a heated vest the same risk as an electric blanket?
Not exactly. Both use electric heating elements, but setups and distances vary. Electric blankets are generally considered safe when used as intended, but rare EMI cases have been reported—so placement and distance still matter for any heated product.
Do modern pacemakers handle small EMFs better?
Yes—manufacturers design devices to tolerate common household EMFs. Problems are more likely with very close, strong sources (large magnets, industrial equipment).
What about people with ICDs as well as pacemakers?
Follow the same or stricter precautions and check the ICD maker’s guidance; ICDs also have magnet/EMI considerations.
Any special travel or day-to-day tips?
Avoid resting phones, smartwatches, earbud cases, or vest batteries over the implant site; keep that 6-inch (15 cm) rule in mind. Carry your device ID card and the vest/battery specs if you’re stopped by security.
Bottom Line
For many people with modern pacemakers, heated vests can be worn safely—if you keep electronics and magnets away from the implant site, use the manufacturer’s battery/charger, and follow your pacemaker maker’s EMI guidance. When in doubt, ask your pacing clinic before use.
