Pre-excitation syndrome
Medical condition
Pre-excitation syndrome is a heart condition in which part of the cardiac ventricles are activated too early.[1] Pre-excitation is caused by an abnormal electrical connection or accessory pathway between or within the cardiac chambers. Pre-excitation may not cause any symptoms but may lead to palpitations caused by abnormal heart rhythms. It is usually diagnosed using an electrocardiogram, but may only be found during an electrophysiological study.[2] The condition may not require any treatment at all, but symptoms can be controlled using medication or catheter ablation.
