Hello and welcome,
Occasional and sudden fast heart beats, pounding,
dizziness,
chest pain that are short in duration are highly suggestive of paroxysmal
supraventricular tachycardia (PSVT). The episode of PSVT usually goes away with vagal maneuvers (coughing, deep breathing, muscle tensing or putting your face in ice-
cold water).
PSVT is an abnormal heart rhythm (
arrhythmia) that occurs when a short circuit rhythm develops in the upper chamber of the heart which results in a regular but rapid heartbeat (150-200/min) that starts and stops abruptly. Alcohol, caffeine,
anxiety, exercise or sudden movements, bending over may trigger the episode of PSVT.
PSVT is diagnosed with continuous heart monitoring (Holter). One time ECG may be normal because the abnormality happens during the episodes.
You did great job by avoiding alcohol, caffeine, quitting
smoking and eating healthy food. These are called life style changes which is initial step for the treatment of PSVT. Your episodes are very rare and short in duration therefor additional treatment is not indicated. Try to avoid situation that triggers the episodes (bending over) and use vagal maneuvers when the episode happens. You should seek medical attention if PSVT episode does not go away with vagal maneuvers or the episodes become longer up to few minutes. Also avoid over-the-counter decongestants or herbal medicines that may also trigger the episode.
I hope the above information will be helpful for you. Please, feel free to ask me if there is anything else you need to know.
Thank you,
