Heart rate drop
When exercising (biking, elliptical machine or walking hills), my pulse can suddenly drop from 120/145 to 85/105. (I wear a chest strap pulse meter.) It takes some time to recover. The explanation given is that a PVC will cause this. Needless to say a drop from 135 to 85 is quite a challenge while working fairly hard. Lately these drops have become more frequent and make it tough to keep exercising. Any thoughts?
