I've completed a pulmonary rehabilitation course 2 weeks ago. Wanted to join the local Breathe Easy group but am exhausted! In fairness I have felt exhausted for ages and suspect it's due to fast heart rate 115 irregular today, (not unusual for me,) and high blood pressure for which I've been given Indapamide 1.5 per day. I am taking Aminophylline hydrate MR 225 twice a day and suspect it's not doing much. Has anyone got any experience of a similar problem?
