Witryna15 wrz 2024 · Introduction. Wide complex tachycardia (WCT) is characterized by a heart rate of more than 100 beats per minute along with a wide QRS complex. 1 In a young patient, WCT causing syncope raises suspicion of an underlying life-threatening arrhythmia.

Challenges in Narrow QRS Complex Tachycardia Interpretation

Witryna26 lut 2024 · Narrow QRS complex tachycardias or Wide QRS complex tachycardias are common problems encountered in clinical practices. Although such tachycardias often occur in patients with a normal anatomy and/or function of heart and rarely represent life-threatening conditions, they are common sources of morbidity and/or … Witryna2 kwi 2024 · Narrow QRS tachycardia is defined as a tachycardia (heart rate >100) with narrow QRS (duration <120 ms). Narrow QRS indicates simultaneous activation of both ventricles. Atrial tachycardias generally have a narrow QRS because their ventricular activation occurs via the AV node and the ventricular conduction system … WitrynaECG showed an irregular narrow complex tachycardia with alternating and gradually changing QRS morphologies after alternating and changing RR intervals, with a clear pattern of 2 alternating QRS complexes.
