What has Changed in the Diagnostic Approach to Arrhythmogenic Cardiomyopathy after Ecg Amplitude Criteria in Lead AvR and V1?

In 2016 most relevant ECG criteria for the diagnosis of arrhythmogenic cardiomyopathy has been published. The amplitude of inverted T-waves in lead aVR (1) and V1 (2) for the evaluation of arrhythmogenic cardiomyopathy was published and contributed to the ECG diagnosis of arrhythmogenic cardiomyopathy significantly.

In 2017 both amplitude criteria were taken together for optimisation of ECG diagnosis even in cases without right ventricular enlargement and aneurysms (3, 4).
For exclusion of arrhythmogenic cardiomyopathy the ECG morphology of lead aVR (5) and the amplitude of inverted T-waves of 2mm or less are extremely helpful.
