I have a question about my resting heart rate. I weigh 140 LBS. and am 5'10". My RHR is 132, I just calculated multiple times, counting the amount of heart beats in 10 seconds and multiplying by 6. 130-132 is the outcome every time. I also want to add in the I took my daily prescribed adderall a good 13-14 hours ago, in case that has to do with it. Other than that, the only other stimulant I have had was a cup of coffee about 6 hours ago. Thank you for your help.
