pubmed-article:3238396 | pubmed:abstractText | Cardiogoniometry (CGM), an orthogonal lead system using four chest leads, was performed in a population of 120 healthy volunteers. The measurements were taken simultaneously with the conventional ECG at rest, after upright bicycle exercise at 50 watts, and immediately and 6 minutes after maximal symptom limited exercise. The results of these tests are the normal values for CGM. The normal values are located in a narrow band on the spherical surface of the coordinate system. | lld:pubmed |
