Welcome to HCM.
Do not worry.Transient Fluctuations in heart rate
is a common thing. Heart rat usually increases in some physiological conditions like exercise, hypovolemia
As far as my guess goes the increase in heart rate in your case might be due to anxiety or stress or acute panic attack
. Using anxiolytics like alprazolam will help you. You have not mentioned about your profession or your life style. If of late you have had increased work load or psychological stress at office or at home, then try to relax a bit and if possible go for meditation
or spend some time with the family members.
But get an ECG done to rule out any conduction abnormalities of heart.Hope it turns out to be normal. If the problem is severe and really disturbing then see a cardiologist and if the ECG is found normal then see a psychiatrist
and take his advice.
Wish you a speedy recovery.
