I had an echo and a 2-5 min stress test wasnt long I'm 18 male, excercise alot! Heart rest rate is 100-130 usually high. Cardiologist said I'm fine!?

I assuming . Your echo and stress test was negative. Are you overweight? Daytime sleepiness point toward sleep apnea. Also can give increase hr. If heart ok, then increase resting hr can happen b/c lack of physical conditioning, excess coffee and energy drinks, dehydration, cold meds, street drugs like marihuana, hyperthyroidism, arrhythmias, Anabolic steroids etc. Stay with your primary care doctor.
