Have A Feeling Like Fainting And Heart Beat Slowing Down. No Test Done Or Medication. What Can Be The Problem?

Hello Doctor. So, today in gym class we were playing whiffle ball which is like baseball. After running around for a little while my heart beat got really slow and my eyes started to go black but not completely. I also felt kind of faint and I felt like I needed to sit. This has happened to me many times before in basically the same type of scenario where I will run or do some form of exercise and then feel like I'm about to pass out. I think it might be because I don't really exercise that much but I am very healthy and not overweight so I would really like to know why this happens and what I can do to make it stop happening. Thank you!

Hi friend,
Welcome to Health Care Magic

The heart rate and blood pressure must rise with exercise – failure to do so may result in near syncope, as in your case. You need further investigations –

A thorough history and physical examination is the first step - ECG (Electrocardiogram / EKG) – Routine 12-lead – is part of clinical examination.
HOLTER (24 to 48 hour ambulatory monitoring) is done to analyse and plan for irregular beats.
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) – it can assess the heart rate and BP during exercise...

See a Cardiologist

Take care
Wishing speedy recovery
God bless
Good luck
