2017年8月22日 · The ECG shows a very wide QRS complex tachycardia (QRS duration 280 ms) with variation in morphology. Following a pause of 700 ms, there are repeating sequences of 6 to 7 beats with cycle lengths of 400 to 415 ms.

2019年4月1日 · The presenting ECG shows an irregular monomorphic wide complex tachycardia. The differential diagnosis of wide complex tachycardia includes ventricular tachycardia (VT), supraventricular tachycardia (SVT) with aberrant His-Purkinje conduction, and supraventricular tachycardia with ventricular activation using an accessory pathway.

2020年11月3日 · irregular waves of varying morphology and amplitude; Management. immediate cardioversion; amiodarone

2017年8月11日 · This shows an irregularly irregular wide complex tachycardia at a rate of about 120. Of course, whenever confronted with a wide complex tachycardia, one must consider ventricular tachycardia. However, unless it is polymorphic VT (which has multiform QRS complexes), VT is never this irregular.

2024年8月9日 · Wide complex tachycardia suggests a problem with your heart’s electrical activity. Some conditions that cause wide complex tachycardia aren’t serious, while others can be life...

Tachycardia refers to heart rate >100/min in an adult. Tachycardias are classified as regular or irregular, narrow complex or wide complex; The underlying causes of tachycardia are legion; Types of tachycardia. Narrow complex tachycardias. Regular Sinus tachycardia; Atrial tachycardia; Atrial flutter; Supraventricular tachycardia; AVNRT ...

2023年6月26日 · To put it all together, a WCT is considered a cardiac dysrhythmia that is > 100 beats per minute, wide QRS (> 0.12 seconds), and can have either a regular or irregular rhythm. This article will be covering WCT’s etiologies, epidemiology, evaluation, management, treatment, prognosis, complications, and prevention.

Her 24-hour Holter monitor demonstrated incessant wide QRS complex tachycardia with a mean ventricular rate of 124 bpm. Figure 1 demonstrated the 12-lead electrocardiogram (ECG) before and during wide QRS complex tachycardia.

2020年5月19日 · In this review, we provide an in‐depth analysis of traditional and more contemporary methods to differentiate ventricular tachycardia and supraventricular wide complex tachycardia.

Wide refers to a QRS complex duration (width) of greater than or equal to 0.12 seconds (120 msec), corresponding to three small boxes on the ECG paper. There are many reasons for QRS complexes to be widened (see Table 1).
