“…Daniel Cortez first described the S-wave angle in lead V2 as an early presentation of arrhythmogenic cardiomyopathy controlled by 66 probands without heart disease [5]. The first measurements were done by a protractor.…”

The sensitivity of this parameter was 97%, specificity was 81%, and negative predictive value was 99%. T wave inversion in lead V1 with an amplitude of ≥2 mm The same author presented this marker as a typical finding in patients with arrhythmogenic cardiomyopathy also in cases with T wave inversion only in lead V1 [8]. Children below the age of 14 years were excluded, the mean age of this cohort was 46.8±11.8 years. In bipolar precordial leads, a T wave inversion of ≥3 mm in lead V1 has been described as a typical finding [9]. Controlled by the same number of normal probands, the sensitivity was 93%, specificity was 97%, and negative predictive value was 99%. Combination of the above-mentioned features If typical ECG abnormalities in lead aVR and T wave inversion in lead V1 were combined, the sensitivity was 94%, specificity was 99%, and negative predictive value was 99.9% [10,11]. QRS fragmentation in all leads Fontaine described QRS fragmentation as "pre"-, "top"-, and "post"-silon in patients with typical arrhythmogenic cardiomyopathy in high values [12]. QRS fragmentation is an unspecific finding and can be described in a large number of other diseases like hypertrophic or dilated cardiomyopathy, long QT syndrome, and Brugada syndrome [13]. Conclusions There are indeed ECG parameters of concealed arrhythmogenic cardiomyopathy which enable the diagnosis at a very early phase. Ajmaline challenge in an early stage is positive in some cases. These are patients with a very high risk of ventricular fibrillation described by Corrado [14] and Peters [15]. Perhaps these are those patients with sudden cardiac death as the first manifestation of the disease.

: Revision of the Task Force diagnostic criteria (TFC) for arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) in 2010 has increased their sensitivity for diagnosis of early and familial forms of the disease. Epsilon wave (EW) is a major diagnostic criterion in the context of ARVC/D, however, it remains not quantifiable and therefore may leave room for substantial subjective interpretation, thus explaining existing interobserver variability in assessment of EW is high. EW, when present, coexists with other disease characteristics, which are sufficient for ARVC/D diagnosis, which makes EW generally not required for ARVC/D diagnosis. Nevertheless, EW remains an important part of electrocardiographic phenotype of ARVC/D that may be useful in planning diagnostic workup, which needs to be recognised.
