Extrasystole is a medical term often used in cardiology to describe an abnormal, irregular heartbeat. Specifically, it refers to a premature contraction of the heart's ventricles, which occurs earlier than expected during the normal cardiac cycle.
During a normal heart rhythm, an electrical signal originating from the sinoatrial node stimulates the atria to contract, followed by the ventricles, leading to coordinated and efficient pumping of blood. However, in extrasystole, an additional electrical impulse arises from an abnormal site, often in the ventricles, resulting in an early and irregular heartbeat. These extra beats can give the sensation of a skipped or missed beat, followed by a strong and forceful heartbeat.
Extrasystoles can be caused by various factors, including stress, caffeine, nicotine, certain medications, or underlying heart conditions like heart disease or electrolyte imbalances. In many cases, extrasystoles are harmless and do not require treatment. However, if they occur frequently, are associated with other symptoms such as chest pain, dizziness, or shortness of breath, or if they are a manifestation of an underlying heart condition, further investigation and management may be necessary.
Treatment options for extrasystoles may include lifestyle modifications, such as reducing stress or avoiding triggers like caffeine or tobacco, as well as medication or procedures aimed at controlling the abnormal heart rhythms. Medical professionals, such as cardiologists, specialize in diagnosing and managing extrasystoles, ensuring optimal heart health and well-being for affected individuals.
