protodiastolic

protodiastolic

 [pro″to-di″ah-stol´ik]
pertaining to early diastole, i.e., immediately following the second heart sound.

pro·to·di·a·stol·ic

(prō'tō-dī'ă-stol'ik), This word is ambiguous, referring to both the beginning of physiologic diastole (before aortic valve closure) and the beginning of auscultatory diastole (after aortic valve closure). S3 gallop is therefore preferred to protodiastolic gallop.
Early diastolic, relating to the beginning of cardiac diastole.

At the same time by increased HR and improving ventricular diastolic function, (increased transmitral protodiastolic pressure gradient, i.e., increased atrial pressure) and shortening of left ventricular isovolumetric relaxation time there is early mitral valve opening and early left ventricular filling by enhanced ventricular suction.
These include advanced age, protodiastolic gallop, ventricular arrhythmia, and more commonly used parameters such as left ventricular ejection fraction (LVEF), QRS duration, and New York Heart Association (NYHA) functional class.[sup][4],[5],[6] Several factors are widely used in routine practice.
Women with a high-resistance index (>0.55) and/or a protodiastolic notch in the placental side or in both uterine arteries were diagnosed as having abnormal uterine Doppler (25) and were eligible to enter the study.
(18) Other important predictors of mortality in DCM patients include advanced age, protodiastolic gallop, failure of the myopathic ventricle to respond to inotropic stimulation, ventricular arrhythmias, prolonged ECG QRS duration, reduced left ventricular function, and late gadolinium enhancement on cardiovascular magnetic resonance imaging.
The sound often is referred to as a protodiastolic gallop or ventricular gallop.
We categorized patients as having ventricular systolic dysfunction if they had an ejection fraction (EF) [less than or equal to]45% and diastolic dysfunction in the presence of one of the following patterns (15,16): (a) abnormal relaxation [peak protodiastolic transmitral velocity (E)/peak late diastolic transmitral velocity (A) <1 and deceleration time of the mural E wave (EDT) >140 ms in patients less than 55 years of age, or E/A <0.8 and EDT >140 ms in subjects more than 55 years of age]; (b) pseudonormal (1 < E/A <2 and EDT >140 ms; diastolic wave of pulmonary veins on Doppler test superior to the systolic wave for differentiation from the normal pattern); (c) restrictive (E/A >2 and EDT <140 ms).
