Will My Heart Rate Monitor Strap Be Accurate if I Have a Pacemaker or ICD?
Garmin’s heart rate monitor straps (HRMs) are not designed for use with pacemakers or ICDs, nor have they been tested with these devices. Garmin cannot guarantee the accuracy of the heart rate data from our HRMs if you have a pacemaker or ICD. The HRM data is not intended to be used for medical purposes, nor is it intended to diagnose, treat, cure, or prevent any disease or condition. Garmin recommends you consult your doctor before engaging in any exercise routine.
