Arrhythmogenic cardiomyopathy

Abstract

Electrocardiography (ECG) is a critically important modality in the investigation of patients with cardiomyopathy of any kind, including arrhythmogenic cardiomyopathies. In some specific arrhythmogenic cardiomyopathies, the ECG is to some extent diagnostic, e.g. QRS microvoltages in the extremity leads to PLN-associated cardiomyopathy and prolonged PQ interval with a narrow QRS in laminopathies. In others, it contributes to the diagnosis, e.g. an epsilon wave, negative T waves beyond V1-V2 and a prolonged terminal activation duration in V1 in arrhythmogenic right ventricular cardiomyopathy (ARVC). Most often, however, these ECG features exhibit high specificity by low sensitivity. Electrocardiographic features are also included in risk calculators, risk for future cardiac arrhythmic events, that have been described in recent years. An example of the latter is the number of precordial leads with negative T waves in ARVC.
