Dizziness, variable heart beats, decreased heart beat while exercising. Should I get this checked?

For the last couple years my heart sometimes felt like it stopped for a few seconds only when I was lying down many times and I get this scary sinking feeling and dizziness . About six months ago I felt one while I was up and driving my car, I thought it might be because of stress that day. But just today I was on treadmill and my heart rate was steady at 138, then all the sudden I felt weird and confused when my heart felt like it stopped for a second and my heart rate plunged from that down to 128 down to 98 down a couple more times until it was at 50, then went back up again by multiplies of 10. This happended 4 times in 30 mins. Should I get this checked out? I have been going to the gym and walking on treadmill 70 mins 3 days a week for last 6 weeks and this is the first time it has happened.

Cardiologist 's  Response
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
