[|Human|] I am a 31 year old female and my heart just speeds up for a bit then goes back to its original beat I have had a ecg done before the first time this happened and the ecg said there was nothing wrong I was told that this happenes to people all the time
[|AI|]  Hello, Occasional and fast heartbeats are highly likely paroxysmal supraventricular tachycardia (PSVT) episode. It is an abnormal heart rhythm 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. ECG can show rapid heartbeat only during the episode. Diagnosis of PSVT requires continuous heart monitoring (Holder) to catch the episode. For rare and short duration episodes treatment is not indicated. Lifestyle changes can greatly help to prevent PSVT episodes. Try to find out a situation that triggers the episodes and avoid those situations. Alcohol, caffeine, anxiety, exercise or sudden movements may trigger the episode of PSVT. During the episode, you may use legal maneuvers (coughing, deep breathing, muscle tensing or putting your face in ice-cold water) to stop it. You should seek medical attention if PSVT episode does not go away with legal maneuvers or the episodes become longer up to a few minutes. Also, avoid over-the-counter decongestants or herbal medicines that may also trigger the episode. Hope I have answered your query. Let me know if I can assist you further.
