Effect of flecainide on left ventricular ejection fraction

European Heart Journal, 1987
Antiarrhythmic agents may depress cardiac contractility and worsen heart failure. Flecainide is an effective antiarrhythmic drug, but when administered orally in patients with left ventricular (LV) dysfunction, its effect on LV function is unknown. To assess the effects of flecainide on cardiac function, LV ejection fraction (LVEF) was measured by ...

The effects of stress on left ventricular ejection fraction

European Journal of Nuclear Medicine, 1988
The left ventricular ejection fraction (EF) was studied in 17 healthy volunteers with a new ambulatory left ventricular function monitor. Heart rate, EF, and blood pressure measurements were made during rest, a psychiatric stress interview, cold exposure, exercise, and eating.

Left Ventricular Geometry and Survival in Patients With Normal Left Ventricular Ejection Fraction

The American Journal of Cardiology, 2006
In hypertensive populations, left ventricular (LV) geometry, which is characterized by hypertrophy, predicts cardiovascular outcome. The left ventricle can also alter its shape by concentric remodeling (CR) in the absence of LV hypertrophy, a feature that is detected by echocardiography. This study assessed the prevalence and prognostic significance of

Left Ventricular Size and Ejection Fraction

Heart Failure Clinics, 2019
Despite the rapid development of emerging imaging technologies, left ventricular ejection fraction represents the cornerstone of diagnosis, choice of treatment, and prognosis in heart failure. However, true myocardial function often remains underestimated or overestimated in different conditions underlying this heterogeneous syndrome.

Left atrial ejection fraction is an indicator of left ventricular diastolic function

The International Journal of Cardiovascular Imaging, 2021
Left atrial ejection fraction (LAEF) has been previously shown to accurately distinguish between patients with and without clearly defined left ventricle diastolic dysfunction (LVDD) by ASE/EACVI criteria, but indeterminate cases were excluded. We sought to determine if LAEF could accurately distinguish between normal, indeterminate and LVDD patients ...

Determination of left ventricular volumes and ejection fraction by echocardiography

The American Journal of Cardiology, 1970
In the past few years remarkable advances have been made in accuracy of cardiac diagnosis by external graphic techniques. The latest of these, echocardiography, differs from previous methods in that it penetrates the surface of the chest to provide information regarding movements of ventricular walls, septum and valves.

Left Ventricular Ejection Fraction and Results of Cardiac Surgery

Cardiology, 2008
The results of prosthetic valve replacement in 64 patients and coronary revascularization or aneurysmectomy in 58 patients were analyzed 1 year after the operation. 24 early and late deaths were found to be associated with a technical complication of surgery, new myocardial infarction, or in some instances persistent, unexplained heart failure.

Measurement of right and left ventricular ejection fraction in dogs

Clinical Physiology, 1983
Summary. Three techniques for measurement of right (RVEF) and two techniques for left (LVEF) ventricular ejection fraction were evaluated in five dogs. RVEF was measured with a first‐pass radionuclide technique using erythrocytes labelled in vitro with Technetium‐99m methylene disphosphonate (MDP) and compared with RVEF measured with a thermodilution ...

Cine MR determination of left ventricular ejection fraction

American Journal of Roentgenology, 1987
Cine MR imaging provides tomographic images of the heart with both high spatial and high temporal resolution. As many as 32 images per cardiac cycle can be acquired with up to four separate anatomic slices and a total imaging time of 128 cardiac cycles.

Comparison of Left Ventricular Ejection Fraction Calculation Methods

Echocardiography, 1998
Left ventricular ejection fraction (LVEF) has been used for many years to assess left ventricular systolic function. Over time, patients may have LVEF measurements performed with the use of different imaging modalities. It is important for the clinician to appreciate how these different methods compare with each other.
