阵发性心动过速(简称阵速)是内科常见急症之一。顽固性阵速多发生在器质性心脏病基础上,持续时间长或多次反复发作,治疗效果差,常引起严重的血液动力学异常,部分室性阵速可恶化为心室颤动导致猝死(急性心肌梗塞伴室性阵速者约52％转为心室颤动),故必须紧急而有效地予以纠正。本文仅就室性阵速和室上性阵速的诊治要点从实用的观点予以简要的说明。
Paroxysmal tachycardia (referred to as speed) is one of the common medical emergency. Occurrence of refractory stupor in the basis of organic heart disease, prolonged or repeated attacks, the treatment effect is poor, often causing severe hemodynamic abnormalities, some of the ventricular tachycardia can lead to sudden death due to ventricular fibrillation ( Acute myocardial infarction with ventricular tachycardia about 52% converted to ventricular fibrillation), it must be urgently and effectively be corrected. This article only on the ventricular velocity and supraventricular tachycardia diagnosis and treatment points from a practical point of view to give a brief description.
