ECG abnormalities that may be observed in arrhythmogenic right ventricular dysplasia

  Complete or incomplete right bundle branch block

 
Epsilon wave: a very infrequently observed late potential

 
Negative T waves in right and mid precordials

 
Ventricular arryhthmias (usually as left bundle branch block morphology)

ECG 1. Epsilon wave in a patient with ARVD. To detect the epsilon wave, the ECG was recorded at a paper speed of
50mm/second and at a calibration of 20mm/mV by Fontaine modification.

ECG 5. ECG of a patient with arrhythmogenic right ventricular dysplasia (ARVD). No Epsilon wave is seen.
Negative T waves are seen in the right precordials (V1-V3).

ECG 6. Another patient with ARVD. No Epsilon wave is seen.
Negative T waves are seen in the right and mid- precordials (V1-V4).

Dr. Frank Marcus has donated this ECG to our website.





ECG 7. The above ECG belongs to a patient with ARVD. Arrows point to the Epsilon wave.

ECG 8. Above is the ECG of a 17 years-old girl with arrhythmogenic right ventricular dysplasia (ARVD).

Giant Epsilon waves are seen in leads C1 and C2
. Epsilon waves of lesser amplitude are also seen in limb leads.
The wide QRS complex on the left
is an end-diastolic ventricular premature contraction.
