Intraventricular early diastolic filling during acute myocardial ischemia, assessment by multigated color m-mode Doppler echocardiography.
BACKGROUND Color M-mode Doppler echocardiography has been suggested as a new noninvasive technique for assessing left ventricular diastolic function. The present study investigated intraventricular filling pattern by color M-mode Doppler in patients during percutaneous transluminal coronary angioplasty (PTCA). In a dog model of myocardial ischemia, the color M-mode flow pattern was related to i...
متن کاملAlternations in Intraventricular Filling Pattern by Color Doppler M-mode during Induced Myocardial Ischemia
It has been shown that regional myocardial ischemia during angioplasty is associated with retarded apical filling. To test the importance of retarded apical filling by color Doppler M-mode to detect ischemia during dipyridamole (DIP)stress echo we evaluated 29 patients (pts) (12 females, age 57±87 years).The high dose DIP (0.84 mg/kg over 10 min) was used. The color M mode record was used to ca...
متن کاملComparison between M-Mode and Doppler echocardiography in diagnosis
Introduction: Patent ductus arteriosus (PDA) is the persistence of a normal fetal structure between left pulmonary artery and descending aorta. Persistence of this fetal structure beyond 10 days of life is considered abnormal. In this study we compared M-Mode and Doppler echocardiography in diagnosis of PDA in children at Aliasghar Hospital in Zahedan and Children hospital in Bandar Abbas for...
متن کاملInfluence of Alteration in Preload on the Pattern of Left Ventricular Diastolic Filling as Assessed by Doppler Echocardiography in Huumans
was recorded simultaneously with pulsed Doppler echocardiography of left ventricular inflow and M-mode echocardiography of left ventricular diameter. Chamber stilfness constants, kd and k1, were obtained from the diastolic pressure-diameter and pressure-volume relations, respectively. Relaxation was measured by the isovolumic relaxation time constants, TL and TD, derived from the exponential le...
متن کاملInfluence of alteration in preload on the pattern of left ventricular diastolic filling as assessed by Doppler echocardiography in humans.
We examined the influence of alterations in preload on pulsed Doppler indexes of left ventricular diastolic function in 50 patients including 12 without cardiovascular disease, 29 with coronary artery disease, and nine with critical aortic stenosis. Micromanometer left ventricular pressure was recorded simultaneously with pulsed Doppler echocardiography of left ventricular inflow and M-mode ech...
