Q: what could cause a high resting heart rate like 100 to 110 while resting?

A few possibilities: Dehydration &amp;/or meds &amp;/or obesity. If you haven't got one, you need a12-lead ECG to determine what is going on. There is a nerve-based pathway in the heart that looks like an upside-down tree. The pacer is the sinus node. It shoots electricity to the AV node where the left and right bundle branches originate. Then the pathways branch over &amp; over. "Ectopic"/extra sites misbehave &amp; cause this too.
