心房扑动时的F 波可根据在肢导Ⅱ、Ⅲ、aVF 中是尖端向下或向上分为普通型(又称尾-头型)或非普通型(又称头-尾型)。F 波在同一人的不同时期尖端方向可发生变化,但在同次、同导联中F 波尖端发生逆转者,比较罕见。现报告一例于后:临床和心电图分析 F wave of atrial flutter flutter can be divided into common type (also known as tail - head type) or non - ordinary type (also known as head - tail type) according to the tip II, III, aVF tip down or up. F wave in the same person at different periods of the tip direction can change, but in the same time, the same lead in the F wave tip reversal were relatively rare. Now report a case later: clinical and electrocardiographic analysis
