May improve sensitivity for prior MI detection over ECG; leaves open need for prospective validation before clinical adoption.
Does the Frank vectorcardiographic lead system improve the detection of myocardial infarction compared to the standard 12-lead electrocardiogram in patients with suspected myocardial infarction?
Vectorcardiography may provide superior diagnostic sensitivity for detecting past myocardial infarction compared to standard 12-lead electrocardiography.
Hugenholtz et al. (1961) studied this question.
