100年多年前,心电图学之父Einthoven首先提出等边三角理论,并由此创用了心电图Ⅰ、Ⅱ、Ⅲ标准导联。此后,Wilson等又创用了aVR、aVL、aVF加压单极肢体导联,形成六轴导联体系。以后由于胸导联的出现和Ⅰ、Ⅱ导联的普遍重视,aVR导联成了常常被疏忽的导联。近年来,aVR导联被人们重新认识,无论在窦性心律的判定、室上性心动过速的 Einthoven, the father of electrocardiography, first proposed the theory of equilateral triangle more than 100 years ago and created standard leads of ECG Ⅰ, Ⅱ and Ⅲ. Since then, Wilson has also created aVR, aVL, aVF compression unipolar limb lead to form a six-axis lead system. Later, due to the appearance of thoracic lead and the general importance of lead Ⅰ and Ⅱ, lead aVR has become the often neglected lead. In recent years, aVR lead was re-recognized, both in the determination of sinus rhythm, supraventricular tachycardia
