Dear sir/mam, i was diagnosed with sinus tachycardia a month ago..i was having palpitations and heart beat around 110 to 120 bpm.. doctor told me to take ciplar la 40 for three weeks and then to stop it...i followed the same..but after two days of stopping ciplar la 40,i suddenly started feeling palpitations again and my resting heart beat was 110 to 120 bpm again..i consulted the doctor again and he told to continue ciplar la 40.. I want to ask how long i have to take medicine..is there not any other cure?? Doctor told me that it's bcoz of anxiety..also i have high triglyceride value 230..my thyroid level is fine...plz tell the solution for this sinus tachycardia
