Should a fixed external reference system be used to analyze left ventricular wall motion?
To investigate whether a fixed external reference system should be used to most accurately describe regional left ventricular wall motion, we used vectors to analyze a simple model of ventricular contraction. If measured in a fixed external reference system, motion of implanted radiopaque midwall markers may contain translational as well as contractile components. Therefore, comparisons of diff...
متن کاملLeft Ventricular Wall Motion
The effects of sublingual nitroglycerin (GTN) on left ventricular wall motion (LVWM) were examined by angiographic assessment in eight patients with anginal chest pain. Five of seven patients having occlusive coronary artery disease showed segmental abnormalities in LVWM characterized by regional hypokinesis or akinesis at rest. These abnormalities were accentuated by tachycardia induced by atr...

متن کاملShould contrast be routinely used for echocardiographic assessment of left ventricular function? A matter of appropriateness.
Hoffmann et al. present data showing that contrastenhanced echocardiography, compared with unenhanced echocardiography, provides more accurate determination of left ventricular ejection fraction and significantly improves the correlation with cineventriculography and magnetic resonance imaging (MRI). Certainly, the most important question arising from this study is whether contrast injection sh...
متن کاملLeft ventricular wall motion response to intravenous propranolol.
The effects of intravenous propranolol on left ventricular wall motion and hemodynamics were studied in 16 patients, 12 with significant coronary artery disease and four with chest pain but no coronary disease. Eight patients received 0.10 mg/kg and eight received 0.15 mg/kg of propranolol intravenously. All underwent atrial pacing at a constant rate. Left ventricular angiograms were performed ...
