Welcome to Health Care Magic
The first thing to do / and you have to do yourself / IS TO STOP SMOKING...
Smoking is bad even for a normal heart / you should avoid even passive smoking
The next step is to see a cardiologist.
Arrhythmias may be part of the original defect / or result of treatment.
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
