I have been using a Garmin for about 10 years now (both before and after my Valve replacement in 2010 and my ICD in early 2015). One thing I have learned is that they are very sensitive to dry, cold weather. By that I mean I will get very erratic readings during the first few minutes of a run (occasionally up to the first 10 minutes). Normally I can get away with just running the chest strap under the sink to moisten it, but during the winter months I will use a lube (I buy the Target version of water based KY Jelly....works great and it is cheap).
My wife never had luck with chest straps due to some scar tissue, so she tried out the Garmin 225 that reads HR from the wrist and has had lots of success with it.
