  • Title: [Assessment of corrected orthogonal ECG system of McFee-Parungao leads in bicycle exercise test in patients with myocardial ischemia].
    Author: Komarova OA, Kotova LA, Iarnykh EV.
    Journal: Ter Arkh; 2001; 73(8):24-8. PubMed ID: 11599260.
    Abstract:
    AIM: To assess orthogonal ECG system McFee-Parungao in exercise test performed by patients with ischemic heart disease (IHD). MATERIAL AND METHODS: The trial included 103 patients: 41 patients with IHD, 23 patients with IHD combined with arterial hypertension and 39 control patients free of IHD. All the patients performed bicycle exercise with ECG registration in the corrected orthogonal system of leads modified according to McFee-Parungao. In 11 patients ECG was registered in two systems--orthogonal and standard 12-lead. Sensitivity and specificity in IHD were assessed. RESULTS: Parameters of the bicycle exercise test registered by ECG in the corrected orthogonal system indicated that sensitivity and specificity of this system in IHD patients are not inferior to sensitivity and specificity of the standard 12-lead ECG system. CONCLUSION: The system of orthogonal leads McFee-Parungao is recommended for use in the practice of bicycle exercise tests in IHD patients.
