[|AI|]  Hi, Welcome. Palpitations & tachycardia could be normal sinus tachycardia due to anxiety or stress, or it could be supra ventricular arrhythmia. For the diagnosis you have to do ECG at the time of palpitations & increased heart rate to know the exact tachycardia. I can understand your situation that despite doing all the tests you are not able to find a cause. I am advising you for some more tests which may make your tachycardia apparent for diagnosis. These are Stress Echo, holder monitoring & thyroid profile. Stress echo will detect any arrhythmia during stress. Holder monitoring is 24hr ECG monitoring to continuously detect your heart rhythm. Follow up after these tests so that further management could be planned. Thanks
