Hello,
You are highly likely experiencing episode of
supraventricular tachycardia. Paroxysmal supraventricular tachycardia (PSVT) starts abruptly with rapid, regular heart beat and stops on its own. Some patients may also experience
lightheadedness,
chest discomfort, sweating or breathlessness.
Usually, there are no any structural abnormalities in the heart but abnormal electric conduction in the heart chambers causes rapid heartbeat. The diagnosis can be confirmed by ECG, holter monitoring or electrophysiological studies.
The occasional episodes of PSVT without any other symptoms commonly have a good prognosis. PSVT is induced by certain risk factor which you should avoid: alcohol, caffeine,
nicotine, illegal drug use and stress.
Life style changes such as regularly exercising and eating healthy food rich in fruits and vegetables helps to prevent PSVT episodes.
To stop the episode of PSVT you may try vagal manures such as
Valsalva maneuver (ie, forceful attempted exhalation against a closed airway), breath holding, carotid massage or immersing your face in ice-cold water.
But if the rapid heartbeat does not stop in a few minutes, new symptoms develop or the episodes become more often you should contact your cardiologist.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Malik Amonov
