Fig. 1From: Impact of type 2 diabetes mellitus on left ventricular diastolic function in patients with essential hypertension: evaluation by volume-time curve of cardiac magnetic resonancea, b. Volume-time curves (a) and first derivatives (dV/dt) (b) depicted by Argus. c, d The meaning of volume-time curves parameters: peak ejection rate (PER) and peak filling rate (PFR) were determined as peak incremental volume changes, where volume-time curve was steepest, first derivative (dV/dt) was maximal positive or negativeBack to article page
