Evaluation of LV diastolic function from color M-mode echocardiography.
OBJECTIVES this study evaluated early diastolic filling dynamics using a semiautomated objective analysis of filling velocities obtained from color M-mode echocardiography. BACKGROUND diastolic function can be evaluated from color M-mode echocardiography by measuring the early diastolic flow propagation velocity (Vp) from the slope of a single linear approximation of an isovelocity contour. H...

متن کاملContrast M-mode Ultrasonography
Contrast M-mode and two-dimensional ultrasonography of the inferior vena cava were performed in 65 patients with various acquired and congenital cardiac disorders. After saline was injected into a peripheral arm vein, the inferior vena cava was visualized by both methods in 60 patients (92%). The M-mode approach was better for correlating the appearance of contrast within the inferior vena cava...
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 کاملPre-Implant Assessment For Optimal LV Lead Placement In CRT: ECG, ECHO, or MRI?
Cardiac resynchronization therapy (CRT) improves cardiac function in many patients with ventricular dyssynchrony. The optimal use of imaging for pre-implantation assessment remains a subject of debate. Here, we review the literature to date on the utility of echocardiography and cardiac MR, as well as conventional ECG, in choosing the best site for LV lead implantation. Prior to the use of imag...
