Missed heartbeat

A sudden premature heartbeat beyond a regular heartbeat is called premature beats (premature beats). Premature beats may be asymptomatic, and may also have palpitations or palpitation. Frequent premature beats reduce cardiac output, or cause fatigue, dizziness, and chest tightness when cerebral blood supply is insufficient, and can exacerbate angina pectoris or heart failure. When measuring the pulse by hand, you can find that the pulse is unstable, jumps early or "misses." Premature beats can occur occasionally or frequently. Premature beats can occur in patients of any age.
