Summary:Various corrected and combined vector magnetocardiographic (VMCG) lead systems have been designed and studied by using a physical, realistic torso model. Although having quite ideal lead fields, many of these new lead systems produce a low signal level, thus lowering the actual information capacity of the lead system. Furthermore, the combined lead systems are technically complex and slightly impractical to use. The corrected unipositional lead system was found to be free of all these disadvantages. This system has a simple geometry consisting of three coaxial detector coils located on the point V2 of the standard 12-lead ECG. On the other hand, its accuracy for the determination of the magnetic heart vector was concluded to be sufficient. Based on the VMCG measured on normal subjects, it was also stated that the lead system has a low sensitivity to the displacement of the detector.
