Atrial flutter is a type of supraventricular tachycardia caused by a re-entry circuit within the right atrium
Atrial flutter occurs when a “reentrant” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute; the atrial rate in atrial fibrillation is 400 to 600 bpm. ...
Atrial Flutter (AFL) :心房扑动 AFL是一种普遍的心律异常,始于心脏的心房。初次发生时,通常与心率快有关,并被归类为SVT类型。 Ventricular Flutter (VF) :心室扑动 这是一种不稳定的心律失常,心律过速影响心室,每分钟超过150-300次。室颤是可能导致心源性猝死的室颤和纤颤之间的过渡阶段。正弦波形没有t波和...

心肌的兴奋性增高,不应期缩短,其频率较阵发性心动过速更高,同时伴有一定的传导障碍,易于形成折返激动,是主要的发生原因,心房扑动 atrial flutter,心电图特征 1. 无正常P波,代之连续的粗齿状F波。F波间无等电位线,波幅大小一致,间隔规则;、 aVF导联中清晰,通常认为心房扑动是在心房形成环形激动的结果,大多...
1. Atrial Flutter 1).There are no P waves in ECG 2).Presence of saw-tooth flutter wave (F waves). 3).F waves always uniform in size ,shape and frequency. 4).Regular atrial rhythm with a rate of 250-350 per minute. 5).Ventricular response of 1:1,2:1,3:1,4:1,or higher. 6...
(mostly paroxysmal), which is two-channel ECG signals each sampled at 250 samples per second with 12-bit resolution over a range ± 10 mV for 10 h. The rhythm annotation files were prepared manually. The rhythm annotations of types are atrial fibrillation (AF), atrial flutter (AFL), ...
