In 1994, an International Task Force proposed criteria for the clinical diagnosis of arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) that facilitated recognition and interpretation of the frequently nonspecific clinical features of ARVC/D. This enabled confirmatory clinical diagnosis in index cases through exclusion of phenocopies and provided a standard on which clinical research and genetic studies could be based. Structural, histological, electrocardiographic, arrhythmic, and familial features of the disease were incorporated into the criteria, subdivided into major and minor categories according to the specificity of their association with ARVC/D. At that time, clinical experience with ARVC/D was dominated by symptomatic index cases and sudden cardiac death victims-the overt or severe end of the disease spectrum. Consequently, the 1994 criteria were highly specific but lacked sensitivity for early and familial disease.
Revision of the diagnostic criteria provides guidance on the role of emerging diagnostic modalities and advances in the genetics of ARVC/D. The criteria have been modified to incorporate new knowledge and technology to improve diagnostic sensitivity, but with the important requisite of maintaining diagnostic specificity. The approach of classifying structural, histological, electrocardiographic, arrhythmic, and genetic features of the disease as major and minor criteria has been maintained. In this modification of the Task Force criteria, quantitative criteria are proposed and abnormalities are defined on the basis of comparison with normal subject data.
The present modifications of the Task Force Criteria represent a working framework to improve the diagnosis and management of this condition. Clinical Trial Registration clinicaltrials.gov Identifier: NCT00024505.

    • "SAECG was positive for late potentials (3/3 time domain criteria; Fig. 3A). Traditionally, it has been common practice to state that the SAECG is positive if 2 of the 3 variables are abnormal (filtered QRS duration ≥ 114 ms, duration of terminal QRS b 40 μV ≥38 ms and root-mean-square voltage of terminal 40 ms ≤20 μV) [12]. However, the sensitivity and specificity of any one of the time domain criteria are similar to that of any 2 or 3 of these criteria and, therefore, any one of the criteria is considered a minor criterion for ARVC [19].

    ABSTRACT: There is increasing evidence that regular intense endurance exercise can promote structural and electrical remodeling of the right ventricle (RV). These physiological changes can be profound and are frequently accompanied by ECG changes in the right precordial leads, thereby mimicking features observed in arrhythmogenic right ventricular cardiomyopathy (ARVC). Because the 12-lead ECG is used as both a screening and diagnostic tool for the detection of conditions associated with sudden death in athletes, it is of fundamental importance to have a good understanding of the ECG features that distinguish physiological adaptations to endurance exercise from those related to RV pathology as well as their potential overlap. This article describes ECG findings observed in healthy endurance athletes versus athletes with underlying RV pathology and illustrates their differentiation using 4 case presentations.

    • "A residual variability in QRS duration in successively performed exams is, thus, observed in the same patient [5]. Notwithstanding, the QRS duration is the most important index for the risk stratification of ventricular arrhythmia [6] [7]. By averaging successive beats, it is possible to reduce the interference or noise whereas relevant signal waveforms are preserved, allowing the identification of VLPs [8]. "

    ABSTRACT: The accuracy of high resolution electrocardiogram (HRECG) as a risk stratification tool relies on QRS offset detection, which is subject to variation due to the signal residual noise level (RNL). This study proposed a technique for improving the accuracy of QRS complex limits detection, based on successive signal derivation (DER), and compared the results with the statistical method recommended by the American College of Cardiology (ACC). Population: Control Group - 18 healthy volunteers (age: [mean ± SD] 52.1 ± 10.2 years) with no cardiac disease; SMVT Group - sustained monomorphic ventricular tachycardia: 18 subjects confirmed by electrophysiology study (58.7 ± 12.9 years). All were in sinus rhythm. HRECGs were analyzed according to ACC guidelines in vector magnitude (VM) high-pass filtered at 40 Hz, averaged to target RNL of 0.2 μV. In DER, HRECGs were successively derived toward the end of the ventricular activation seeking for next higher derivative inflection point, in which absolute amplitude was equal to RMS baseline noise. Sensitivity, specificity and predictive values were compared by X2 test. QRS offset was assessed as function of different RNLs and linear correlation coefficient compared (α < 0.05). ACC and DER methods showed, respectively, 64.3% and 85.7% positive predictive value (p < 0.05), 58.6% and 59.1% negative predictive value (p = NS), 50.0% and 33.3% sensitivity (p = NS), and 72.2% and 94.4% specificity (p < 0.05). According to ACC and DER methods, QRS duration correlated to RNL respectively, in Control Group -0.98 (p < 0.05) and -0.32 (p = NS), and in SMVT Group -0.75 (p < 0.05) and -0.67 (p = NS). DER showed higher accuracy and less sensitivity to RNL than ACC for QRS offset detection.

    ABSTRACT: Arrhythmogenic cardiomyopathy (ACM) is an acquired progressive disease having an age-related penetrance and showing clinical manifestations usually during adolescence and young adulthood. It is characterized clinically by a high incidence of severe ventricular tachyarrhythmias and sudden cardiac death and pathologically by degeneration of ventricular cardiomyocytes with replacement by fibro-fatty tissue. Whereas, in the past, the disease was considered to involve only the right ventricle, more recent clinical studies have established that the left ventricle is frequently involved. ACM is an inherited disease in up to 50 % of cases, with predominantly an autosomal dominant pattern of transmission, although recessive inheritance has also been described. Since most of the pathogenic mutations have been identified in genes encoding desmosomal proteins, ACM is currently defined as a disease of desmosomes. However, on the basis of the most recent description of the intercalated disc organization and of the identification of a novel ACM gene encoding for an area composita protein, ACM can be considered as a disease of the intercalated disc, rather than only as a desmosomal disease. Despite increasing knowledge of the genetic basis of ACM, we are just beginning to understand early molecular events leading to cardiomyocyte degeneration, fibrosis and fibro-fatty substitution. This review summarizes recent advances in our comprehension of the link between the molecular genetics and pathogenesis of ACM and of the novel role of cardiac intercalated discs.
