Wide QRS Complex Tachycardia - StatPearls - NCBI Bookshelf
Jun 26, 2023 · This article will be discussing a specific group of arrhythmias – Wide QRS complex tachycardia (WTC). It is important to go over some basic definitions describing what WCTs are, what causes them, how to diagnose them, and how to manage/treat them.
QRS Interval • LITFL • ECG Library Basics
Aug 14, 2023 · Normal QRS width is 70-100 ms (a duration of 110 ms is sometimes observed in healthy subjects). The QRS width is useful in determining the origin of each QRS complex (e.g. sinus, atrial, junctional or ventricular). Narrow complexes (QRS < …
Intraventricular Conduction Delay (QRS widening) - LITFL
Oct 8, 2024 · Definition of QRS widening. QRS duration > 100 ms in the presence of a supraventricular rhythm. Most commonly due to bundle branch block or left ventricular hypertrophy. The most important life-threatening causes of QRS widening are: Hyperkalaemia; Tricyclic antidepressant poisoning.
Wide Complex Tachycardia: Symptoms, Causes, and Treatment - Healthline
Aug 9, 2024 · The term wide complex tachycardia refers to any condition that causes a heartbeat over 100 bpm and a QRS complex longer than 120 milliseconds. A QRS complex is a feature of an EKG reading.
Wide QRS Complex Tachycardia: Causes, Symptoms, and Treatment
Mar 25, 2023 · Wide QRS complex tachycardia is a type of abnormal heart rhythm that is characterized by a widened QRS complex on an electrocardiogram (ECG) and a rapid heart rate. It can be a potentially life-threatening condition and requires prompt diagnosis and treatment.
Diagnosis and management of narrow and wide complex …
WCT – Wide complex tachycardias (QRS duration ≥0,12 seconds) indicates the ventricles are not depolarized normally. The vast majority of WCTs originate from impulses generated in the ventricles (ventricular tachycardia being the most common arrhythmia).
Wide QRS complex tachycardias: Approach to the diagnosis
Sep 3, 2024 · A widened QRS complex (≥120 milliseconds) occurs when ventricular activation is abnormally slow for one of the following reasons (see "Wide QRS complex tachycardias: …
Wide QRS complex tachycardias: Causes, epidemiology, and ... - UpToDate
Nov 11, 2022 · A widened QRS complex (≥120 milliseconds) occurs when ventricular activation is abnormally slow for one of the following reasons (see 'Differential diagnosis of WCT' below): • The arrhythmia originates outside of the normal conduction system and below the AV node (ie, ventricular tachycardia [VT])
Monomorphic and Polymorphic Ventricular Tachycardias (Wide QRS …
Some types of tachycardia can be difficult to identify and properly treat. A broad QRS (or wide QRS) complex (width greater than .12 seconds) is known as a broad QRS tachycardia. Wide-complex tachycardias can be seen in two general forms: monomorphic and polymorphic. These.
Wide Complex Tachycardias: Understanding this Complex Condition…
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).
