“…Yet, when the RV hypertrophies, this assumption cannot be made. In RV hypertrophy the mean electrical axis moves rightward in the frontal plane, the R-wave amplitude in lead V 1 increases and the S-wave amplitudes in leads V 5 and V 6 decrease, thus reflecting the increased influence of the RV on the mean electrical axis (30)(31)(32). In the present study, the influence of the RV may likely be negligible since no participant had any sign of RV hypertrophy by ECG or CMR.…”

“…They have been correlated primarily with autopsy data, although some are based on clinical and hemodynamic identification of conditions that impose increased workloads on the right ventricle. [51][52][53][54] The echocardiogram has also been used as a reference standard, but it is less definitive than in LVH because of the complex 3-dimensional shape of the right ventricle and the frequent difficulty of measuring the thickness of the right ventricular free wall.…”

Background: Current standard 12-lead electrocardiogram (ECG) criteria for diagnosing pulmonary hypertension (PH) have a low sensitivity. Although the right-sided chest ECG (V3R V5R) increases the diagnostic accuracy, these additional leads are not routinely recorded. The aim of the present study was to assess the usefulness of the synthesized right-sided chest ECG (Syn-ECG), generated from 12-lead ECG information, in the detection and evaluation of PH. Patients and Methods:The Syn-ECG waveforms in 30 patients with PH, defined as an estimated pulmonary arterial systolic pressure (PASP) >35 mmHg, were compared to those in 30 age-and gendermatched normal subjects. Results:The R wave amplitude and R! S ratio in the Syn-ECGs were significantly (P<0.01) greater in patients with PH than in the controls. The R wave amplitude in the Syn-ECGs exhibited a significant and better correlation (correlation coefficient 0.513 0.596, P<0.001) with the PASP than lead V1 (correlation coefficient 0.375, P=0.02). A receiver-operating characteristic curve analysis showed that the R wave amplitude (AUC 0.802, P<0.001) and R! S ratio (AUC 0.823, P<0.001) in the synthesized V5R was a good predictor of PH. New criteria, including 1) an R in V5R>0.12 mV, and 2) R! S ratio in V5R>0.42, had an improved sensitivity (0.63 and 0.73, respectively) and comparable specificity (0.93 and 0.87, respectively) to the conventional criteria (sensitivity 0.10 0.43, specificity 0.90 1.00). Conclusion:The diagnostic criteria derived from the Syn-ECG provided better diagnostic accuracy than the known conventional criteria from the standard 12-lead ECG. This technique described in the present study may be useful for diagnosing and evaluating PH. (J Nippon Med Sch 2015; 82: 136 145)
