Ventricular Tachycardia (VT)

Ventricular Tachycardia (VT)


Broad complex tachycardias areVT until proven otherwise.

Non-sustained VT is defined as 3 continuousventricular ectopics for <30seconds



Most cases due to damage tothe myocardium and structural heart disease e.g. MI                              Othercauses of VT include:

                                                        Inheritedchannelopathies e.g. Brugada syndrome,

                                                      Arrhythmogenic Right Ventricular Cardiomyopathy(ARVC)

                                                      LongQT syndrome



Pre-syncope, syncope, SOB,chest pain, palpitations



Hypotension,tachypnoea, pallor, raised JVP, Cannon ‘a’ waves



ECG:Monomorphic VT – Regular, Broad complex, AV dissociation, concordance

across chestleads, capture or fusion beats

                                        Echo:To assess for structural abnormality

                                        Diagnosticcoronary angiography +/- PCI

                                        CardiacMRI: Useful when the cause is unclear




Acute: Pulseless VT is a cardiac arrestand should be treated with ALS guidelines

   Chronic: Amiodarone, beta-blockers or mexiletine

   ICD implantation



Death, syncope injuries, medicationside effects, inappropriate ICD shocks



Prognosis without treatmentis poor.

Treatment with ICD improves prognosisbut mortality rate still increased
