The two most common causes are anxiety and sometimes paroxysmal supraventricular tachycardia(PSVT), something that can also be aggravated by anxiety as well as being a very common cause of anxiety.

The way SVT can be recognized as a rule is by the fact that it starts abruptly and ends abruptly, usually with a fairly long pause at the end of the episode. It can last from a few seconds to hours or days, but usually it goes on for a few minutes. . If this happens frequently or lasts for long periods of time, you would do well to see a cardiologist who specializes in arrhythmias, because while SVT is not life-threatening, it can be very disruptive if it occurs frequently or for long periods. The distraction and unpleasant sensation is often enough to make one stop whatever one is doing.
The condition occurs most often in young people and infants.

The following increase your risk for PSVT:

1-Alcohol use
2-Caffeine use
3-Illicit drug use
Symptoms usually start and stop suddenly, and can last for a few minutes or several hours.
If you do not have symptoms or any other heart condition, PSVT may not need treatment.

If you have an episode of PSVT, there are techniques he can try on his own to interrupt the fast heartbeat.

- hold your breath and strain, as if you were trying to have a bowel movement.
- cough while sitting with your upper body bent forward.
-splashing ice water on the face is helpful.
>He should avoid smoking, caffeine, alcohol, and illicit drugs.
AS mentioned if the condition is taking more time or being worse or having other symptoms let him see a cardiologist.
