Is paroxysmal sinus tachycardia serious?

Occasionally paroxysmal sinus tachycardia is generally not serious, but if it persists for a long time, it is more serious.

If the patient usually has bad lifestyles such as staying up late, mental stress, frequent smoking and drinking, it is easy to stimulate sympathetic nerve tension, and at this time vagus nerve tension will be weakened, so there will be paroxysmal sinus tachycardia, which is generally not serious after changing living habits. However, if the patient persists in paroxysmal sinus tachycardia for a long time, accompanied by obvious cardiac discomfort, general weakness and other symptoms, it may be caused by heart failure or other organ diseases of the whole body, which is more serious at this time.
