What really cause extra systole?

Extrasystole, or premature heartbeats, can be caused by various factors, including stress, anxiety, caffeine, alcohol, and certain medications. Underlying heart conditions, such as arrhythmias or structural heart issues, may also contribute to their occurrence. Additionally, lifestyle factors like lack of sleep and excessive physical exertion can trigger these irregular heartbeats. While often benign, persistent or symptomatic extrasystoles should be evaluated by a healthcare professional.
