Fontaine bipolar precordial leads (F-ECG) are used to increase the sensitivity of epsilon wave detection, characteristic of arrhythmogenic right ventricular dysplasia (ARVD/C)
ECG lead positioning. V4R, right sided ECG, Lewis lead, 3-lead, 5-lead, 12-lead ECG and electrode placement on chest and limbs
Epsilon wave is a small positive deflection buried in the end of the QRS complex on the ECG. Characteristic ARVD arrhythmogenic right ventricular dysplasia
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)
