What you are describing sounds a lot like white-coat hypertension - normal readings at home in the 110-118/62-76 range but a jump in the clinic. Your home numbers are the more meaningful ones, and with a normal echo and ECG the picture is reassuring. That said, please do not stop the medicine on your own; a beta-blocker like this should be reduced gradually rather than suddenly, because abrupt stopping can cause rebound rise in pulse and BP. The correct way to settle this question is a proper home BP log: measure twice in the morning before medicine and twice at night, seated with the arm supported after 5 minutes of rest, for 7 consecutive days, and note the average. A 24-hour ambulatory BP monitoring is even better if available. Take that log to your doctor and let the dose be tapered under supervision, with attention to salt intake, weight, sleep and the anxiety component, which clearly plays a part in your case.
Next Steps
Maintain a 7-day twice-daily home BP log (or get 24-hour ambulatory BP monitoring) and do not stop Concor on your own - taper only under medical advice. You are welcome to bring the log for a review consultation with me at Synergy Multispeciality Hospital, Miraj.
