Fig. 5From: Clinical implication of disturbed left atrial phasic functions in the heterogeneous population associated with hypertension or atrial fibrillationReceiver operating characteristic (ROC) curves of differentiators for differential diagnosis in the heterogeneous population. a ROC analysis to differentiate lone AF from healthy controls; b ROC analysis to differentiate isolated HTN group and HTN with PAF group; c ROC analysis to differentiate between lone AF group and HTN with PAF group. AF, atrial fibrillation; cond, atrial conduit phase; HTN, hypertension; LAVI, left atrial volume index; PAF, paroxysmal atrial fibrillation; PALS, peak atrial longitudinal strain; PALSR, peak atrial longitudinal strain rate; pump, atrial booster pump phase; TpS-SD%, the standard deviation of time to peak atrial longitudinal strain corrected by RR intervalBack to article page
