Table 5 Novel right-precordial and vectorcardiographic values compared to ARVD/C patients and 2010 Taskforce criteria values currently used

From: Right precordial-directed electrocardiographical markers identify arrhythmogenic right ventricular cardiomyopathy in the absence of conventional depolarization or repolarization abnormalities

  SPQRS-T angle (degrees) RPD angle (degrees) RtRMS-QRS (millivolts)
Epsilon-wave +, n = 13 54.4 ± 31.3 100.5 ± 42.5 1.0 ± 0.8
Epsilon-wave -, n = 142 54.6 ± 42.0 81.2 ± 31.2 0.9 ± 0.4
TAD > = 55 ms, n = 17 67.0 ± 41.1 92.9 ± 40.7 0.7 ± 0.3a
TAD < 55 ms, n = 138 53.1 ± 41.1 81.7 ± 31.4 0.9 ± 0.5a
No T-wave inversion/only in V1, n = 26 56.7 ± 31.0 83.8 ± 33.8 1.0 ± 0.6
T-wave inversion V1-V2, n = 56 35.0 ± 28.0a 87.5 ± 31.8 0.9 ± 0.4
T-wave inversion V1-V3 or beyond, n = 73 67.7 ± 46.8 78.1 ± 32.4 0.8 ± 0.4
