Problem In Tachycardia, Heart Rate Consistently Runs In 90. EKG And Holter Monitor Normal. Any Test To Detect This?

I m a 39 year old male. My heart rate consistently runs in the 90 s. I have had some issues with tachycardia in the last few months that comes and goes. The doctors so far have not been able to find anything wrong. My EKGs and holter monitor did not show anything. What should I be looking into now. I do not drink caffeine.

Hi friend,
Welcome to Health Care Magic

You may have to repeat the Holter for a longer duration...Event monitors usually detect
TMT (Treadmill exercise ECG) / LABORATORY work-up – may be necessary

Anxiety / Alcohol / Tobacco (smoking) / Caffeine (too much coffee, cola) are common causes.
Medicines may be responsible – like Phenylephrine, Pseudo-ephedrine used for ‘cold’ / Salbutamol, Salmeterol used for asthma and so on.
Illicit ‘drugs’ like Amphetamine are notorious to cause abnormal beats

At times, abnormal nerve paths in the heart (bypass tracts) are responsible! -
If there are no clues and if the problem is still bothering to the extent of interfering with life style, there is Electro Physiological Studies (EPS) for its evaluation...

Take care
Wishing speedy recovery
God bless
Good luck
