Ventricular tachycardia (VT): ECG criteria, causes, classification ...
网页Ventricular tachycardia (VT): types, causes, ECG features and management. This chapter deals with ventricular tachycardia from a clinical perspective, with emphasis on ECG diagnosis, definitions, management and clinical characteristics. Ventricular tachycardia is a highly nuanced arrhythmia which originates in the ventricles.

网页ECG features: P waves are often hidden – being embedded in the QRS complexes; Pseudo R’ wave may be seen in V1 or V2; Pseudo S waves may be seen in leads II, III or aVF; In most cases this results in a ‘typical’ SVT appearance with absent P waves and tachycardia
Ventricular Tachycardia – Monomorphic VT • LITFL • ECG Library
网页2023年3月19日 · Ventricular Tachycardia (VT) is a broad complex tachycardia originating from the ventricles. There are several different forms of VT — the most common is monomorphic VT, which originates from a single focus within the ventricles. ECG features of monomorphic VT

网页2021年11月1日 · A. Tachycardia refers to a rapid heart rate — anything higher than 100 beats per minute (bpm). But supraventricular tachycardia (SVT) tends to be less severe and occur in younger people. Ventricular tachycardia (VT) is more likely in older people with heart disease and can be far more serious.
Sinus tachycardia & Inappropriate sinus tachycardia - ECG & ECHO
网页The types of sinus tachycardia are as follows: Normal (physiologic) sinus tachycardia: The automaticity (rate of spontaneous depolarization) in the sinoatrial node is increased during physical activity, stress and nervousness.
Diagnosis and management of narrow and wide complex …
网页NCT – Narrow complex tachycardias (QRS duration <0,12 seconds) indicate the ventricles are depolarized via the His-Purkinje system and thus the impulse originates in the atria (i.e the arrhythmia is supraventricular). WCT – Wide complex tachycardias (QRS duration ≥0,12 seconds) indicates the ventricles are not depolarized normally.
