I have high BP and tachycardia since 2012. Every test has been and nothing is working out. Specially for tachycardia whenever I take medicines initially it is effective then after days it doesn't have any effect. Currently taking metoprolol 150 mg (50 mg thrice, ntp 25 mg ,prazosin 5 mg, diltiazem 90 Sr, cilnidipine 10 mg ,losartan 50 and etc. Though my BP is under control but tachycardia still happens specially as the medicine time comes. Did my holter and it showed sinus tachycardia only. Done all tests for endocrinologist related. Please help me and if possible suggest me some good doctor in Mumbai so I can start the treatment. I don't have anxiety or stress for sure as I'm happy go person.
