I've suffered heart palpitations/flutters since my teens (now late 20's) predominantly brought on by anxiety, posture or rigourous movement. if my booked ecg proves normal would it be safe to take ritalin for recently diagnosed adhd?

Trial only: The answer will be in your symptoms if you start it. If worsening of your arrhythmia or symptoms such as lightheadeness or chest pain you might not be able to tolerate it in the long run. An ecg would only provide limited information as it is usually done at rest and you might need a cardiologist evaluation that might include a loop monitor or Holder in order to assess your baseline palpitations.

Dr Hickerson and another doctor agreed

Yes but..: Most patients with palpitations can take stimulants but a thorough cardiac evaluation that may include a holster monitor and an echocardiogram to rule out serious arrhythmias and structural heart defect. On a positive note, most people with palpitations do not have a serious heart condition.

Dr Kuitems agreed
