【文章內(nèi)容簡介】 s ? Premature Atrial Contractions (PAC)：伴隨著窄的 QRS ? Premature Junctional Contractions (PJC)：伴隨著窄的 QRS ? Premature Ventricular Contractions (PVC)：伴隨著寬的 QRS ?臨床上，比較具有重要意義的是 新出現(xiàn)的PVC，特別是在心肌梗塞後的病人身上。 Ventricular Arrhythmias ? Slow Idioventricular escape rhythm: 寬的 QRS plex，心室速率約 30~40 beats/min ? AIVR (Accelerated IdioVentricular Rhythm):心室速率 40 beats/min，但是不超過 110~120 beats/min ? Ventricular Tachycardia: 心室速率超過 120~130 beats/min ?
