Welcome to Health Care Magic
Active / running / only at bed time / normal bi-annual examination / duration one year - all these point out the condition is not serious; may only be anxiety
However, at 50+, you should see a cardiologist... EKG / HOLTER (24 to 48 hour ambulatory monitoring) / ECHOcardiogram
/ TMT (Treadmill exercise ECG) / LABORATORY work-up – may all be necessary for further assessment and assistance.
The treating doctor may suggest them depending on need, based on his assessment of the situation.
Wishing speedy recovery
