An ectopic heartbeat, or ectopics, is a heart rhythm disturbance that occurs when an impulse originates from a site other than the SA or AV node. In this article, we will discuss three main points about ectopics on ECG: what they look like, what causes them, and how to treat them. Stay tuned for more information.
An ectopic heartbeat is a heart rhythm disturbance that occurs when an impulse originates from a site other than the SA or AV node. The ectopic focus can be anywhere in the atria, ventricles, or Purkinje system. When an ectopic focus is present, the electrical impulses conducted through the heart are disturbed, which can lead to changes in the ECG.
Ectopics on ECG usually appear as premature beats. Premature beats can occur in healthy individuals and are often benign, but they can also be a sign of underlying cardiovascular disease. In some cases, ectopics can lead to more serious arrhythmias such as atrial fibrillation or ventricular tachycardia.
There are three main types of ectopics on ECG:
- Atrial ectopics: These premature beats originate in the atria, the upper chambers of the heart. Atrial ectopics are also called premature atrial contractions (PACs) or atrial premature complexes (APCs). PACs are common and usually benign. They may be caused by factors such as stress, caffeine, alcohol, tobacco use, or medications.
- Ventricular ectopics: These premature beats originate in the ventricles, the lower chambers of the heart. Ventricular ectopics are also called premature ventricular contractions (PVCs) or ventricular premature complexes (VPCs). PVCs are common, and most are benign. However, PVCs can be a sign of heart disease, and they may lead to more serious problems such as ventricular tachycardia (VT).
- Atrioventricular ectopics: These premature beats originate in the atrioventricular (AV) node, which is located between the atria and the ventricles. AV ectopics are also called premature atrioventricular contractions (PAVCs) or atrioventricular premature complexes (APCs). PAVCs are less common than PACs or PVCs, but they can be a sign of heart disease.
Treatment for ectopic beats depends on the type of ectopic and the underlying cause. In most cases, ectopic beats are harmless and don’t require treatment. However, if ectopics are frequent or occur with other symptoms, such as chest pain or shortness of breath, medical attention may be needed.
In conclusion, ectopics on ECG are relatively common and usually harmless. However, if ectopics are frequent or occur with other symptoms, medical attention may be needed.
