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

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

	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 ± 0.3^a
TAD < 55 ms, n = 138	53.1 ± 41.1	81.7 ± 31.4	0.9 ± 0.5^a
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 ± 28.0^a	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

^aindicates significantly different novel parameter values per 2010 Taskforce ECG parameter differentiation mentioned
