Determination of Diastolic Function by Radionuclide Ventriculography

Ventricular function by radionuclide ventriculography in malignant hypertension.

Malignant hypertension is a unique and natural model for the study of abnormalities of left ventricular function due to arterial hypertension, because the development and regression of these abnormalities can be observed in a short period. Studies of ventricular function by radionuclide ventriculography, either before or after therapy, have not been previously reported in malignant hypertensive...

surgery: etiologic classification by radionuclide ventriculography

Early after open heart surgery, cardiac shock due to tamponade is easily misdiagnosed as ventricular dysfunction. The distinction is critical to successful therapy. We assessed the utility of 99mTc-red blood cell, gated equilibrium radionuclide ventriculography in 50 patients with early postoperative cardiac shock after historical, clinical, and invasive hemodynamic evaluation failed to identif...

Pericardial effusion swinging heart phenomenon by dynamic radionuclide ventriculography.

asymptomatic after the unipolar lead was changed to a bipolar system. Monitoring artificial pacemaker function is an important application of ambulatory electrocardiography. Of 48 patients with suspected pacemaker malfunction reported by Iyengar et al., 24-hour monitoring detected failure in nine in whom routine examination, standard electrocardiograms, and pacemaker evaluation clinics failed t...

Can right ventricular performance be assessed by equilibrium radionuclide ventriculography?

Although right ventricular function may be examined by following the passage (first pass) of a bolus of radionuclide through the right heart before it reaches the left heart, the counts detected with conventional gamma cameras in such a short time interval are low; moreover, repeated determinations would result in an unacceptable radiation burden to the patient. We have modified the gated equil...
