2022年2月4日 · Epsilon waves were found in 38% of all patients using S-ECG and increased that to 50% by using F-ECG. The detection rate of epsilon waves using combined methods of ECG recording was significantly higher than that of S-ECG alone (S-ECG 38%; SF-ECG 56%; and SRF-ECG 66%, P=0.0039).

2024年10月28日 · Baseline ECG of a patient with Arrhythmogenic Right Ventricular Dysplasia (ARVD), demonstrating: T-wave inversion in precordial and inferior leads, without RBBB pattern; Epsilon wave in V1; Localised widening of QRS in V1-2

If ε waves are suspected from the S-12-ECG, it is recommended to use R-ECG, F-ECG, 16-lead HD-ECG, as well as HR-ECG. The ε wave is considered a major sign of AC according to the 2010 TFC. However, it is relatively rare and present in advanced cases.

Major criteria: Epsilon wave (reproducible low-amplitude signals from end of QRS complex to onset of the T wave) in the right precordial leads (V1, V2, and V3).

On ECG, the epsilon wave is located between the end of the QRS complex and the beginning of the T wave. After the QRS interval (after the return to the isoelectric line), a small-amplitude deflection can be detected, a distinct and tiny wave. Ziad F. Issa MD, ...

Epsilon wave that reflects delayed ventricular depolarization potentials in the right ventricle, visible on surface ECG, represents an extreme form of depolarization abnormality observed in patients with ARVC/D. Localization of the structural substrate in the latest depolarized areas of the right ventricle is the factor that defines the epsilon ...

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) Explore the significance of the Epsilon wave in ECG, its link to Arrhythmogenic Right Ventricular Dysplasia, and how it aids in diagnosis and assessment.

2013年5月5日 · On ARVD.org the latest ECG criteria for ARVD are updated. To enhance detection of ECG abnormalities specific settings to record an ARVD ECG can be used: ECG settings to enhance recording of Epsilon waves. In patients suspected to have ARVD both a normal 12 lead ECG and a Signal Averaged ECG (SAECG) are useful. II. Tissue …

2023年1月20日 · Epsilon wave, the classical ECG finding in arrhythmogenic right ventricular dysplasia is seen at the end of the QRS complex. Epsilon wave is typically seen in right precordial leads though it has been noted in left precordial leads in those with left ventricular involvement.

Epsilon waves were detected by standard 12-lead electrocardiography (S-ECG), right-sided precordial lead electrocardiography (R-ECG), and Fontaine bipolar precordial lead electrocardiography (F-ECG). We found 3 types of epsilon waves: wiggle waves, small spike waves, and smooth potential waves that formed an atypical prolonged R' wave.
