Pericardial effusion swinging heart phenomenon by dynamic radionuclide ventriculography

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...

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...

Walk-through angina phenomenon demonstrated by graded exercise radionuclide ventriculography: possible coronary spasm mechanisms.

was administered directly into the graft with complete relief of pain and resolution of ST segment elevation. Angiography of the graft (Fig. 2, C) now revealed the graft to be patent; there was normal distal runoff from the graft with a 75”; obstructive lesion of the native RCA just distal to the site of graft insertion. Subsequently, pain again developed associated with ST segment elevation. G...

Pericardial effusion after open heart surgery for congenital heart disease.

OBJECTIVES To determine the prevalence and time course of pericardial effusion after open heart surgery for congenital heart diseases and to identify predisposing risk factors. DESIGN AND PATIENTS Prospective assessment of development of pericardial effusion in 336 patients (163 males) undergoing open heart surgery for congenital heart disease by serial echocardiography on days 5, 7, 14, 21, ...
