Radionuclide ventriculography has been used for the assessment of left ventricular diastolic function in hypertension. Compared to cardiac Doppler ultrasound techniques, the radionuclide method offers the advantages of allowing numerous consecutive cardiac cycles to be examined, and of deriving the data of these examinations from automated software computer programs. For better precision, however, adequate instrumentation is required. In addition, correction factors should be applied to overcome the influence of elements such as heart rate, left ventricular end-diastolic volume, as well as the technical influence of the efficiency of counting among individuals. Its application to hypertensive patients enabled the diagnosis of early abnormalities of left ventricular filling rate in about 30% of the population studied before any alteration in indices of systolic function were detected. The mechanism of the alteration of these indices of diastolic filling rate in hypertension, however, is still not well understood.

UI	MeSH Term	Description	Entries
D006973	Hypertension	Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

D002306	Cardiac Volume	The volume of the HEART, usually relating to the volume of BLOOD contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is STROKE VOLUME.	Heart Volume,Cardiac Volumes,Heart Volumes,Volume, Cardiac,Volume, Heart,Volumes, Cardiac,Volumes, Heart

D015637	Gated Blood-Pool Imaging	Radionuclide ventriculography where scintigraphic data is acquired during repeated cardiac cycles at specific times in the cycle, using an electrocardiographic synchronizer or gating device. Analysis of right ventricular function is difficult with this technique; that is best evaluated by first-pass ventriculography (VENTRICULOGRAPHY, FIRST-PASS).
