Clinical Observations with the Frank Precordial Lead System
Several new lead systems for electrocardiography and vectorcardiography have been proposed. Clinical evaluation of these systems is necessary to determine whether they yield useful information in addition to that furnished by conventional leads and whether the same information obtained from conventional leads appears in recognizable form in the new leads. This study is a step toward such an evaluation of one of the proposed lead systems.
