Figure Lengend Snippet: (A) Representative electrocardiogram for determining PTFV1. PTFV1 (mm∙s) was calculated by the duration (s) of the terminal negative part of the P wave in lead V1 multiplied by the absolute value of its amplitude (mm). (B) Distribution of PTFV1 in patients with CAD who underwent PCI. The red bars indicate abnormal PTFV1, and the blue bars show normal PTFV1. CAD = coronary artery disease, PCI = percutaneous coronary intervention, and PTFV1 = P-wave terminal force in V1. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
Article Snippet: These parameters were also automatically analyzed by the MBF-1000 ECG Data Management System (Fukuda Denshi Co., Ltd., Tokyo, Japan) in 1179 patients.
