A member asked:

My dr referred me to a cardiologist for a high resting hr, blood, ecg are normal, no anxiety or coffee, heart seems fine, what else could be wrong?

Normal 60-100: Level of physical fitness, circulating hormones and autonomic nervous system control resting hr. If consistently at or above 100 something maybe wrong. Don't know what blood test were done. Ecg can be normal and still have a heart condition. Stress test and 2d echo to be certain. Endocrine evaluation for overactive thyroid and other endocrine problems. What's your level of fitness/ cardiac conditi.

Probably nothing: Most cases of patients with high resting heart rates are nothing at all, and related to deconditioning or being "out of shape". Only very rarely is it something else.
