Hemodynamics and Echocardiograms Before

چکیده
Ilemodynamic and echocardiographic measurements were obtained in 15 patients prior to cardioversion and immediately, one, three, and five hours after ca ,dioversion of atrial fibrillation to normal sinus rhythm1z4. j ve hours after cardioversion, there was improvement in cardiac index (P < 0.005), in stroke index (P <0.005)1and i11 stroke work index (P < 04)25), but no significant change in heart rate, mean pulmonary capillary wedge psura,...kft atrial dimensions (LAD), left ventricular end-diastolic dimensions (LVEDD), or left ventricular end-systolic dimension (LVESD). At follow-up oneweek to nine months after cardioversion, 10 of the 15 patients (67 percent) remained in normal sinus rhythm. Neither the size of the left atrium, changes in hemodvnamics, LAD, LVEDD. or LVESD, nor the presence or amplihide of the A-wave on the mitral valve echogram correlated with the persistence 0c normal sinus rhYthm.

The effect of amyl nitrite on the mitral valve echocardiogram in presumably healthy young adults.
We analyzed the use of amyl nitrite as a provocative factor in the diagnosis of mitral valve prolapse in a population of healthy young adults. Sixty-five men and 11 women underwent continuous M-mode echocardiographic and phonocardiographic monitoring before, during and after the administration of inhaled amyl nitrite. All of the 76 subjects had normal baseline echocardiograms, and all had a sat...
متن کاملDeterminants of Ventricular Septal Motion
To test the hypothesis that the ventricular septum moves during systole toward the center of ventricular mass (so that the end-diastolic position of the septum within the heart should determine both the direction and the magnitude of septal motion during systole), echocardiograms from patients with several different hemodynamic burdens were analyzed. A linear relation was noted between the end-...
متن کاملChanges in myocardial function and hemodynamics after ligation of the ductus arteriosus in preterm infants.
OBJECTIVE To characterize the changes in systemic hemodynamics and systolic, diastolic, and global myocardial performance after patent ductus arteriosus (PDA) ligation in very-low-birth-weight infants. STUDY DESIGN Echocardiograms were performed on 23 neonates (mean gestational age, 26.2 +/- 2.2 weeks) at 2.3 +/- 2.0 hours before PDA ligation (n = 23) and at 2.0 +/- 1.4 hours (n = 23) and 23....
متن کاملExtracorporeal life support of neonates with congenital cardiac defects: techniques used during cardiac catheterization and surgery.
Neonatal patients with congenital cardiac defects require proper diagnosis often by cardiac catheterization before surgical repair. In our institution, patients whose echocardiograms reveal surgically correctable lesions, but who are severely decompensated, have been placed on Extracorporeal Life Support (ECLS) prior to catheterization or surgery. Subsequent management of ECLS and cardiopulmo...
متن کاملLeft ventricular resynchronization therapy in a canine model of left bundle branch block.
Positive responses to left (LV) and biventricular (BV) stimulation observed in heart failure patients with left bundle branch block (LBBB) suggest a possible mechanism of LV resynchronization. An anesthetized canine LBBB model was developed using radio frequency ablation. Before and after ablation, LV pressure derivative over time (dP/dt) and aortic pulse pressure (PP) were assessed during norm...
