Hazards for speeders: It can cause fatigue, dizziness and other symptoms (due to reduced cardiac output). It can induce or aggravate angina or heart failure in people with existing heart disease.

The highest incidence rate is between 50 and 70 years old. About 5% of healthy people may develop premature beats. Premature beats occur, which can reduce stroke volume. However, premature beats less than 6 times per minute have almost no impact on physical health (physiologically).
