异位快速心律失常是指起源于窦房结以下部位的心律失常。包括心房、房室结、希司一浦顷野系统或心室。常见形式为心动过速、颤动、扑动等。它可以发生在无器质性心脏病者,但更多见于有器质性心脏病者。不论在何种情况下发生,由于其可减少心排出量引起血压下降,导致心脏等器官供血不足,严重者可以发生心绞痛、急性心衰, 甚至猝死。因而必须快速、有效地对异位快速心律失常进行处理。
Ectopic tachyarrhythmia refers to arrhythmias that originate in the following parts of the sinus node. Including the atria, atrioventricular node, Hirsch-Ushima system or ventricular. Common forms of tachycardia, fibrillation, flutter and so on. It can occur without organic heart disease, but more in those with organic heart disease. No matter under what circumstances, because it can reduce cardiac output caused by blood pressure drops, resulting in insufficient blood supply to the heart and other organs, severe angina can occur, acute heart failure, and even sudden death. Therefore, ectopic tachyarrhythmia must be treated quickly and effectively.
