Nov 3, 2020 · Ventricular Tachycardia = 3 or more VEB at a rate of > 130 beats/min. If > 30 seconds = sustained; can be monophoric or polymorphic.

Oct 8, 2024 · A premature ventricular complex (PVC) is a premature beat arising from an ectopic focus within the ventricles. AKA: ventricular ectopics, ventricular extrasystoles, ventricular premature beats, ventricular premature depolarisations. Discordant ST segment and T wave changes. Electrophysiology of Ventricular Ectopics.

Oct 8, 2024 · Three mechanisms exist for initiation and propagation of ventricular tachycardia: 1. Reentry (commonest mechanism) 2. Triggered Activity. 3. Abnormal Automaticity. Monomorphic VT: NB: The rhythm strip is recorded after the other 12 leads rather than simultaneously. Monomorphic VT: Monomorphic VT alternating with ventricular bigeminy.

Nonsustained ventricular tachycardia (NSVT) is a common arrhythmia. It is usually asymptomatic and is typically diagnosed during external cardiac monitoring (eg, continuous ambulatory electrocardiography or inpatient telemetry), pacemaker interrogation, or exercise testing.

Nov 24, 2023 · Non-sustained ventricular tachycardia (NSVT) is an ectopic ventricular rhythm with wide QRS complex (120 milliseconds or greater), rate faster than 100 bpm, lasting for at least 3 beats that spontaneously resolves in less than 30 seconds.

NSVT in the absence of apparent structural heart disease. Idiopathic Ventricular Tachycardia: Ventricular outflow arrhythmias (RVOT > LVOT). Good prognosis, rarely associated with tachycardia-induced cardiomyopathy and sudden cardiac death (SCD).

Apr 22, 2023 · Non-sustained ventricular tachycardia (NSVT, or non-sustained V-tach) is an abnormal heart rhythm (arrhythmia) that starts in the lower chambers of the heart (ventricles). NSVT is three or more consecutive heartbeats at a rate of more than 100 beats per minute (bpm) and lasts for less than 30 seconds.

Mar 9, 2010 · Nonsustained, repetitive, monomorphic VT. This is the most common form (60%-90%). It is characterised by frequent ventricular ectopy, right ventricular couplets and salvos of non sustained ventricular tachycardia (NSVT) with left bundle branch block morphology and inferior QRS axis.

Mar 19, 2023 · For unstable patients: obtain an ECG, stabilize with cardioversion, and pontificate about the ECG later on. Algorithms for sorting out VT from SVT are notoriously fallible. When in doubt, it is safer to err on the side of over-diagnosing VT and treating the patient accordingly.

Oct 8, 2024 · Regular broad complex tachycardias can be ventricular (VT) or supraventricular (SVT with aberrancy) in origin, and differentiation between the two will significantly influence management of your patients. Unfortunately, the electrocardiographic differentiation of VT from SVT with aberrancy is not always possible.
