  • Title: [Evaluation of head-chest lead ECG in the diagnosis of acute right ventricular infarction].
    Author: Ding WH, Zhang JH, Shao G.
    Journal: Zhonghua Nei Ke Za Zhi; 1992 Apr; 31(4):217-9, 254. PubMed ID: 1424999.
    Abstract:
    The clinical features, hemodynamic parameters, Wilson's lead and head-chest (H-C) lead ECG of 23 cases with acute right ventricular infarction (ARVI) were analyzed. Results showed that 13 cases revealed clinical right heart failure, but 10 of them had clear lung fields. 11 cases showed hypotension. 20 cases had mean right atrial pressure (MRAP) > or = 10 mmHg. The remaining 3 cases had MRAP between 8 mmHg and 10 mmHg, but it was > or = 10 mmHg after volume loading. The ratio of MRAP to pulmonary wedge pressure was > 0.65 and the right ventricular stroke work index < 5.0 g.m/m2 in all the 23 cases. ST elevation > or = 1 mm in V3R to V6R was found in 12 cases (52%), while ST elevation > or = 1 mm in HV3R to HV8R in 20 cases (87%). The results showed that the diagnostic accuracy for ARVI with H-C lead (right chest) ECG is higher than that with Wilson's lead. H-C ECG is better correlated with hemodynamics in patients with ARVI.
