In many of my patients, I keep track of their pulse rate and blood pressure. And in patients treated with stimulant medications, I routinely compare their pulse rate and blood pressure soon after they wake up to measurements taken several hours later, that is, before they have taken the stimulant medication and around the time that the stimulant medication they are on is expected to have its peak serum level.
For more on this, please see the following article on this website: How exactly should blood pressure be monitored in persons on stimulants
One of my patients, a young man with ADHD, had an elevated heart rate and mild palpitations during the day, even though he did not have any known cardiovascular disease, and was still on a relatively low dose of a stimulant medication. He was reluctant to continue increasing the dose of the stimulant medication because of this increased heart rate, even though I pointed out to him that he was on too low a dose of the stimulant medication for his ADHD to be adequately treated.
