27 Ventricular Arrhythmias

28 Epidemiology of VA & SCD Classification of Ventricular Arrhythmia by Electrocardiography Nonsustained ventricular tachycardia (VT) ♥ Monomorphic ♥ Polymorphic Sustained VT ♥ Monomorphic ♥ Polymorphic Bundle-branch re-entrant tachycardia Bidirectional VT Torsades de pointes Ventricular flutter Ventricular fibrillation

29 Nonsustained Monomorphic VT

30 Nonsustained Polymorphic VT

31 Ventricular Flutter Spontaneous conversion to NSR (12-lead ECG)

32 VF with Defibrillation (12-lead ECG)

33 Epidemiology of VA & SCD Classification of Ventricular Arrhythmia by Clinical Presentation Hemodynamically stable ♥ Asymptomatic ♥ Minimal symptoms, e.g., palpitations Hemodynamically unstable ♥ Presyncope ♥ Syncope ♥ Sudden cardiac death ♥ Sudden cardiac arrest

34 Epidemiology of VA & SCD Classification of Ventricular Arrhythmia by Disease Entity Chronic coronary heart disease Heart failure Congenital heart disease Neurological disorders Structurally normal hearts Sudden infant death syndrome Cardiomyopathies ♥ Dilated cardiomyopathy ♥ Hypertrophic cardiomyopathy ♥ Arrhythmogenic right ventricular (RV) cardiomyopathy

35 VA: Diagnosis Chemistry panel Resting ECG Ambulatory ECG –Holter monitor, event monitor, or ILR Stress testing –Exercise or pharmacologic –ECG, echoc, or SPECT MPI Left ventricular function & imaging –TTE, LHC, CCT, or CMR Electrophysiologic testing

36 Antiarrhythmic Drugs ♥ Beta Blockers: Effectively suppress ventricular ectopic beats & arrhythmias; reduce incidence of SCD ♥ Amiodarone: No definite survival benefit; some studies have shown reduction in SCD in patients with LV dysfunction especially when given in conjunction with BB. Has complex drug interactions and many adverse side effects (pulmonary, hepatic, thyroid, cutaneous) ♥ Sotalol: Suppresses ventricular arrhythmias; is more pro- arrhythmic than amiodarone, no survival benefit clearly shown ♥ Conclusions: Antiarrhythmic drugs (except for BB) should not be used as primary therapy of VA and the prevention of SCD Therapies for VA

37 Non-antiarrhythmic Drugs ♥ Electrolytes: magnesium and potassium administration can favorably influence the electrical substrate involved in VA; are especially useful in setting of hypomagnesemia and hypokalemia ♥ ACE inhibitors, angiotensin receptor blockers and aldosterone blockers can improve the myocardial substrate through reverse remodeling and thus reduce incidence of SCD ♥ Antithrombotic and antiplatelet agents: may reduce SCD by reducing coronary thrombosis ♥ Statins: have been shown to reduce life-threatening VA in high-risk patients with electrical instability ♥ n-3 Fatty acids: have anti-arrhythmic properties, but conflicting data exist for the prevention of SCD Therapies for VA
