2024年10月8日 · Sinoatrial exit block is due to failed propagation of pacemaker impulses beyond the SA node. The sinoatrial node continues to depolarise normally. However, some of the sinus impulses are “blocked” before they can leave the SA node, leading to intermittent failure of atrial depolarisation (dropped P waves).

2014年11月7日 · Supraventricular premature or ectopic beat (atrial or nodal) 室上性早搏(发生于心房或者房室结的统称为室上性，室上性早搏，是说早搏介于房性和室性之间，属于轻微的心率失常)

An atrial escape beat occurs after a long sinus pause resulting from sinus node exit block or sinus node arrest. [2] Atrial escape beats can become a sustained atrial rhythm when three or more escape beats occur in a row at a rate above 60 bpm.

2025年2月18日 · The combination of atrial fibrillation with a regular rhythm (“regularised AF”) indicates that none of the atrial impulses are conducted to the ventricles, i.e. complete heart block is present; The narrow complex rhythm is therefore a junctional escape rhythm; Regularised AF is characteristically seen as a consequence of digoxin toxicity

连续3个或3个以上的房性逸搏即构成 房性逸搏心律 (atrial escape rhythm)。 1.偶尔可在健康人中出现。 2.房性逸搏及逸搏心律是一种少见的被动性异位心律,多在重度窦性心动过缓、窦房结暂时被抑制、窦房阻滞、窦性停搏、房室传导阻滞、房性期前收缩长间歇之后时发生。 下部心房心律，如 冠状窦性心律 失常发生在洋地黄中毒、急性心肌梗死、急性风湿热、重度呼吸衰竭等患者，以及迷走神经张力增高时。 左心房逸搏心律多见于各种器质性心脏病，但健康人也可出现。 窦房结 …

An atrial escape beat occurs after a prolonged pause resulting from SA exit block or sinus arrest. 3 or more atrial escape beats occurring consecutively at a rate above 60 bpm is atrial escape rhythm.

2024年9月17日 · Escape atrial beats may occur after a long sinus pause, usually resulting from sinus node exit block or sinus node arrest (waveform 1) (see "Sinoatrial nodal pause, arrest, and exit block"). If the pause is long enough, there will be an escape atrial rhythm at a rate correlating with the intrinsic automaticity of the atrial focus.

2021年2月15日 · Atrial escape is an impulse generated by an atrial focus in the context of a long sinus pause, such as due to sinus arrest or third degree sinoatrial exit block. Look For Ventricular rate 60bpm

2020年3月7日 · .atr 为注释文件，记录了心电专家对相应的心电信号的诊断信息。 在大多数记录中，第一条信号是MLII型（通过将电极置于胸部而获得），第二条信号通常是V1（偶尔是V2或V5，在一个实例中是V4）。 现将各记录中导联类型统计如下： 注释是指向记录中的特定位置并描述这些位置上的事件的标签。 下面表格包含心跳注释和非心跳注释（信息来源） 文章浏览阅读2.8w次，点赞26次，收藏173次。 MIT-BIH心律失常数据库详解介绍注释标记说明介绍来 …

Three or more consecutive beats from a latent pacemaker (or other ectopic focus) are referred to as an escape rhythm. In most cases, the escape rhythm originates in either of the following three structures (discussed in detail in Chapter 1):
