2024年4月4日 · A narrow QRS complex (<120 ms) reflects rapid activation of the ventricles via the normal His-Purkinje system, which in turn suggests that the arrhythmia originates above or …

Narrow QRS complex tachycardias are fast cardiac rhythms (generally more than 100 beats/min) with a QRS duration of 100 ms or less. 1 Although rarely life-threatening, these arrhythmias …

2023年1月31日 · Atrial tachycardia (unifocal or multifocal) diagnose by taking an atrial electrogram (CVL, atrial epicardial, oesophageal) stop digoxin and theophylline (cause or …

2022年9月12日 · What are Narrow-Complex Tachyarrhythmias? Narrow-complex tachyarrhythmia is a broad term to cover any of several types of arrhythmias in which the heart beats faster …

Narrow complex tachycardias generally do not cause circulatory compromise and are therefore easier to manage than wide complex tachycardias. The latter (WCT) is in the vast majority of …

Narrow QRS complex tachycardia (NCT) represents an umbrella term for any rapid cardiac rhythm greater than 100 beats per minute (bpm) with a QRS duration of less than 120 …

2015年5月5日 · As the impulse goes down the normal conduction pathway, the QRS complex is narrow. The impulse then propagates slowly across the ventricular myocardium before …

A narrow QRS complex (<120 milliseconds) reflects rapid activation of the ventricles via the normal His-Purkinje system, which in turn suggests that the arrhythmia originates above or …
