@JohnnyDoe thank you so much for your interest that your chest pain is heart disease or not. All kinds of chest pain is not heart disease. It is caused by hyperacidity or anxiety or other stress like condition.Even though if you are anaemic, you can feel palpitation also.If your age is 26 then your age is not favourable for heart disease rather than any congenital anomaly such as tetralogy of Fallot’s.
If you have confusion then you can do investigations of ECG /Echocardiogram,Lipid profile.
Your resting heart rate 70 beat /minute and during jumping 90/100 beat /minute is completely within normal physiological limit.
Stay safe and healthy. If you have further question,can ask.Thanks a lot again.
