Check your thyroid function test Then only start other medicines Dr Ashish Srivastava General Physician and Clinical Cardiologist

First check the TSH as ur on thyroid medicine and sometimes if TSH level is very low u have palpitations and u have to reduce the dose. If it is normal then do an ECG and an ECHO to rule out mitral valve prolapse and any form of rhythm issues. If both are normal then do a 24 hr Holter monitoring. I don't think that 80 heart rate will cause palpitations.No we don't give Ciplar la life long. If all the investigations are normal then u don't need ciplar la if yr pulse is less than 100.
