You may have tachycardia
or some sort of cardiac arrhythmia
. Some arrhythmias are not serious while others are very much so. Best to get this checked out again by a physician.
Do you have high blood pressure? Is your resting heart rate
normally high? Tachycardia is a resting heart rate more than ~100 beats per minute (this # depends on the person's size).
Some possible causes (other than heart defects) -- dehydration
, stress, abnormal blood sugar levels, hyper-sensitivity to caffeine or alcohol. Smoking tobacco & various drugs can also account for this.
You blood sugar levels may be out of whack if you are diabetic or if you only eat 1 or 2 meals a day.
