Dr. Tian Hongbo
Premature beats, medically referred to as premature contractions, are one or more extra heartbeats that occur unexpectedly outside the normal cardiac cycle. The main symptoms include:
1. Chest tightness: The altered cardiac rhythm during premature beats may lead to insufficient blood supply to the heart, resulting in a feeling of chest tightness.
2. Fatigue: Premature beats may reduce cardiac blood flow, leading to inadequate oxygen supply and causing fatigue.
3. Palpitations: When premature beats occur, the ventricles are not completely filled with blood or pressure, resulting in an awareness of abnormal heartbeat, which may feel like a sudden acceleration or irregular rhythm.
4. Anxiety or uneasiness: Persistent premature beats may cause psychological discomfort in patients, leading to feelings of anxiety or restlessness.
5. Syncope or dizziness: Severe premature beats may temporarily reduce blood supply, causing syncope or dizziness.
Premature beats do not necessarily indicate serious heart disease; however, frequent or persistent premature beats may require further investigation and treatment, especially in patients with a history of underlying heart disease.
