All my reports are normal CDC, Vitamin D and B12, Renal Profile, Lipid Profile, Thyroid, Xray shows( mild right Hilar Prominence), 2decho, TMT, Coronary Angiography, Holter everything shoes normal apart from one i mentioned in Xray. My resting heart rate is normal below 100 but when i stand and even I walk for 2-3 seconds it goes beyond hundred like 105-108 and walk continuously it even goes beyond 135 but i feel normal. Now, please answer me genuinely, do I have to worry about this. Just walking in my room here and there i see elevated heart rate and once again resting heart rate is normal by resting i meant sitting or lying down its normal . Please help with the right guidance. Thank you !!
