Fig. 2From: Associations among left ventricular systolic function, tachycardia, and cardiac preload in septic patients a Effect plot for heart rate and longitudinal strain; b effect plot for heart rate and ejection fraction among patients with high cardiac preload and controlling for vasopressor dose and APACHE II score. The plots depict thresholds for abnormal strain (−17%) and abnormal ejection fraction (45%) [46]Back to article page
