2024年10月8日 · The term supraventricular tachycardia (SVT) refers to any tachydysrhythmia arising from above the level of the Bundle of His, and encompasses regular atrial, irregular …

2025年1月5日 · Ventricular tachycardia: usually above ~120 b/m. A heart rate close to or higher suggests a non-sinus mechanism. Usually, max heart rate would only be reached under marked physiological stress. Max sinus heart rate would also be expected to be accompanied by AV nodal stimulation (causing a relatively low PR interval).

2023年8月7日 · Supraventricular tachycardia (SVT) is a dysrhythmia originating at or above the atrioventricular (AV) node and is defined by a narrow complex (QRS < 120 milliseconds) at a rate > 100 beats per minute (bpm).

2025年3月17日 · Supraventricular tachycardia (SVT) are a group of tachycardias in which at least a structure above the bundle of His is necessary for its continuance. Supraventricular tachycardias include a number of disorders, atrioventricular nodal reentrant tachycardia and atrioventricular reentry tachycardia being the most frequent.

Supraventricular tachycardia (SVT) is a common cause of hospital admissions and can cause significant patient discomfort and distress. The most common SVTs include atrioventricular nodal re-entrant tachycardia, atrioventricular re-entrant ...

室上性心搏過速 （supraventricular tachycardia，SVT）簡稱 室上速，是指一组起源于房室交界及其以上 传导系统 的 心动过速 [9][2]。 主要可分四型： 心房顫動 、 陣發性室上性心搏過速 （PSVT）、 心房撲動 、 沃夫巴金森懷特症候群 [2]。

2021年12月16日 · Supraventricular tachycardias are usually narrow-complex tachycardias with a QRS interval of 100 ms or less on an electrocardiogram (ECG). Occasionally, they may show a wide QRS complex in the case of a pre-existing conduction delay, an aberrancy due to rate-related conduction delay or a bundle branch block.

tachycardia (SVT) refers to rapid rhythms that origi-nate and are sustained in atrial or atrioventricular nodal tissue, and then transmit through the bundle of His and cause...

Learn more about the cardiac arrhythmia supraventricular tachycardia (SVT), including its ECG characteristics, symptoms, potential causes, and treatment utilizing the ACLS guidelines.

Supraventricular tachycardia (SVT) is defined as an abnormally rapid rhythm (infants >220/ min, and in children >180/min) that originates proximal to the bifurcation of the bundle of His, and is caused by an abnormal mechanism (specifically excluding sinus tachycardia).
