History of the Epsilon Wave. Guy Hugues Fontaine (1936-2018) was a French cardiologist and electrophysiologist.In 1977 he defined and named arrhythmogenic right ventricular dysplasia ARVD; the epsilon wave; and the Fontaine lead placement to best amplify the waves on an ECG. The term “epsilon” was nice, because it occurs in the Greek alphabet after delta; thus, delta represents the pre ...

Minor criteria: Late potentials on signal-averaged ECG in at least one of three parameters in the absence of a QRS complex duration of ≥110 msec on the standard ECG; filtered QRS complex duration, ≥114 msec; duration of terminal QRS complex <40 μV (low-amplitude signal duration), ≥38 msec; root-mean-square voltage of terminal 40 msec ...

Key ECG findings of right heart strain are ST segment depressions and T wave inversions in the right-sided precordial leads V1-V4 and/or inferior limb leads II, III, aVF, typically accompanied by right axis deviation and/or a dominant R wave in V1. 8, 9 ECG evidence of right ventricular strain after a syncopal episode raises concern for ...

Abstract. The ECG is abnormal in most patients with arrhythmogenic right ventricular dysplasia (ARVD). Right ventricular parietal block, reduced QRS amplitude, epsilon wave, T wave inversion in V1-3 and ventricular tachycardia in the morphology of left bundle branch block are the characteristic changes that reflect the underlying genetic predetermined pathology and pathoelectrophysiology.

Arrhythmogenic Right Ventricular Cardiomyopathy, (ARVC, or ARVD: Arrhythmogenic Right Ventricular Disease) is characterized by fatty replacement and fibrosis of the heart.Most commonly the right ventricle apex and outflow tract are involved. However the left ventricle can be affected too.[] As a result of the fatty replacement and fibrosis, ventricular arrhythmias are common in this disease ...

Stages of ARVD. Stage 1 (asymptomatic); The patient is asymptomatic, with no arrhythmias or structural changes in the heart; There are minimal changes on the ECG and imaging studies (MRI, echocardiography); At this stage, ectopic foci and ventricular tachycardia may already develop in the ventricle; Stage 2 (symptomatic); The patient has structural changes (fibrotic and fatty) in the right ...

arrhythmogenic right ventricular dysplasia A rrhythmogenic right ventricular dysplasia/cardiomyopa-thy (ARVD/C) is characterized by progressive loss of predominantly right ventricular (RV) myocardium, which is replaced by fibrofatty tissue.1–3 The gold standard for ARVD/C diagnosis is demonstration of the transmural fibro-fatty infiltration ...

Abstract Background. The purpose of this study was to reevaluate the ECG features of Arrhythmogenic right ventricular dysplasia (ARVD). The second objective was to evaluate the sensitivity and specificity of the standard and newly proposed diagnostic ECG markers in the presence of a right bundle branch block (RBBB).

ECG and Epsilon Wave (ε) Epsilon wave is a small positive deflection at the end of the QRS complex.; It is seen in the leads that "look at" the right ventricle.(V1-V3)About 30% of patients with ARVD have the epsilon wave

Methods and Results— ECG criteria were studied, while off drugs, in 50 index patients with proven ARVD/C according to TFC (TFC ≥4 points) and 33 patients with probable ARVD/C (TFC 3 points, or TFC3), being 21 index patients and 12 family members of proven ARVD/C patients. Newly proposed additional criteria are (1) prolonged terminal activation duration in V 1-V 3, an indicator of ...

OBJECTIVE. The purpose of this study was to describe the structure and function of the heart in the presence of marked lipomatous infiltration of the right ventricular wall in 13 patients referred for second opinions about fatty infiltration of the right ventricular wall and suspected arrhythmogenic right ventricular dysplasia. CONCLUSION. Lipomatous infiltration with right ventricular ...

intervention associated with management of arrhythmogenic right ventricular dysplasia. atty replacement of the myocar-dium is a peculiar condition that has been reported to occur prima-rily in the right side of the heart. Fontaine et al. [1] reported that fat is normally well demarcated from underlying muscle in the right ventricular (RV) free ...

Rate-related left bundle branch block (LBBB) is a well-studied phenomenon. Cardiac memory is another physiologic phenomenon in which T-wave abnormalities occur in the absence of ischemia. The association between these 2 phenomena has been described in several case reports. A literature review was pe …

Guy Fontaine (1936 - 2018) defined arrhythmogenic right ventricular dysplasia; coin the term 'epsilon wave' for the late QRS 'wiggle' seen in 30% of patients; and describe bipolar lead placements to best visualise the characteristic waves (Fontaine leads; F-ECG)

Naxos disease (OMIM 601214) combines palmoplantar keratoderma (PPK) and other ectodermal features characterised by woolly hair with cardiac disorders suggesting arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C).. It has a prevalence of 1 in 1000 in Naxos, the largest of the Greek Cyclades islands, where up to 5% of the population are heterozygote carriers.
