Hi friend,
Welcome to Health Care Magic
No doubt – you should get checked – as soon as possible...
Fall in
heart rate or pressure during exercise is an ominous sign
Dizziness denotes fall in pressure / reduced blood supply to the brain
The first step is to see a Cardiologist / Irregular heart beats need to be DOCUMENTED by ElectroCardioGram (EKG). Standard ECG records the electrical activity of the heart, for a few seconds. It can detect the arrhythmia occurring during that time only. If the episode occurs randomly, you need Holter or event monitor.
ECHOcardiogram is necessary to see the heart valves (
Mitral Valve Prolapse) / heart muscle (
Cardiomyopathy) and heart function (
Ejection fraction, wall motion abnormality) / clots...
TMT – Treadmill exercise ECG; may be with thallium isotope – is necessary to evaluate ischemia (reduced blood flow / Coronary Artery Disease)
You may even need Electro Physiological Studies (EPS)
The treating doctor may suggest them depending on need, based on his assessment of the situation.
Take care
Wishing speedy recovery
God bless
Good luck
