Classification of HTN with and without diastolic dysfunction by E/A ratio and by normalized TH. Probable DD, HTN with DD identified by both E/A ratio and normalized TH; Possible DD , HTN with DD by only one cutoff; Probable No DD, HTN without DD identified by either cutoff; solid black line, cutoff value for E/A ratio; dash black line, cutoff value for normalized TH; DD, diastolic dysfunction; TH, torsional hysteresis.
