Prevalence, Therapeutic Response, and Outcome of Ventricular Tachycardia in the Out‐of‐hospital Setting: A Comparison of Monomorphic Ventricular Tachycardia, Polymorphic Ventricular Tachycardia, and Torsades de Pointes
Abstract:Abstract. Objective: To investigate out-of-hospital ventricular tachycardia (VT) cardiac arrest patients, comparing the prevalences and outcomes of the following VT subtypes among this population: monomorphic VT (MVT), polymorphic VT (PVT), and torsades de pointes (TdP, PVT with a prolonged QT interval). Methods: This was a retrospective review from a fire department-based paramedic system of nontraumatic VT cardiac arrest patients (January 1991 to December 1994) with a supraventricular perfusing rhythm (SVPR)… Show more
“…2,8,10,[13][14][15][16][17] Multiple potential explanations exist to explain these improved outcomes. The model effectiveness may be related to the adaptive, contextual nature of the training based on practice location, provider type, prescribed role in hospital resuscitation events, and patient type as well as the link to performance improvement.…”

“…99 This arrhythmia may cease spontaneously or degenerate into VF. 126,127 When such abnormal QTc values are observed, complete withdrawal of the causative drug or at least a substantial dose reduction should be considered. The list of drugs affecting the QTc interval continues to grow, and an updated list of specific drugs that may prolong the QTc interval can be found at www.qtdrugs.org.…”

PrevalenceThe two constantly growing global health problems (that is, HF and AF) often co-exist, or may precipitate one another. Recent registry-based reports show that ∼40% of patients hospitalized for
“…A serum potassium level above 4 mmol/L may be desirable in HF patients . A normal QRS duration should be provided, since in particular polymorphic ventricular tachyarrhythmias are often associated with QTc values exceeding 500 ms or more . When such abnormal QTc values are observed, complete withdrawal of the causative drug or at least a substantial dose reduction should be considered.…”
