Hi friend
Welcome to Health Care Magic
The situation is highly suggestive of anxiety - still, you should see a cardiologist.
Though the feeling may be normal in some, it is advisable to investigate.
A thorough history and physical examination is the first step -
Routine 12-lead Electrocardiogram (ECG) is part of clinical examination.
If a routine ECG does not show, 24 to 48 hour ambulatory monitoring (Holter) is done to analyse and plan for further management
ECHOcardiogram is necessary to see the heart valves (
Mitral Valve Prolapse) / heart muscle (
Cardiomyopathy) and heart function (
Ejection fraction, wall motion abnormality) – Have you done it?
Treadmill exercise ECG (TMT) is done to exclude
Ischemia (reduced blood flow) – OK in your case
Laboratory work-up is routine - like blood counts, sugar, urea, electrolytes (potassium in particular), thyroid (over-active) etc. The treating doctor will suggest based on the situation.
In the mean time, continue ativan.
Take care
Wishing speedy recovery
God bless
Good luck
