P-wave indices in patients with pulmonary emphysema: do P-terminal force and interatrial block have confounding effects?
INTRODUCTION: Pulmonary emphysema causes several electrocardiogram changes, and one of the most common and well known is on the frontal P-wave axis. P-axis verticalization (P-axis > 60°) serves as a quasidiagnostic indicator of emphysema. The correlation of P-axis verticalization with the radiolo...
