Heart skipping a beat is a term used to describe a common medical condition known as premature ventricular contractions (PVCs). Typically, the human heart maintains a rhythmic pattern of contractions, pumping blood and oxygen throughout the body. However, occasionally, an extra heartbeat occurs before the regular beat resumes.
During a skipped heartbeat, the heart's electrical system becomes disrupted, causing one of the ventricles (the lower chambers of the heart) to contract prematurely. This irregular beat can be felt by the person experiencing it, often described as a brief pause followed by a stronger or more forceful beat.
Heart skipping a beat can be triggered by various factors, including stress, caffeinated beverages, alcohol, tobacco, exercise, and certain medications. While occasional skipped heartbeats are generally harmless and do not require medical attention, frequent or persistent episodes should be evaluated by a healthcare professional to identify any underlying causes or potential risks.
Although typically harmless, people with pre-existing heart conditions, such as heart disease or arrhythmias, may experience more significant symptoms or complications. In such cases, further examination, diagnostics, and treatment may be necessary.
Overall, heart skipping a beat refers to an occasional abnormality in the heart's rhythm, often described as a brief pause followed by a stronger beat. While usually benign, it is essential to seek medical advice if frequent or concerning episodes occur.
