In an attempt to objectively evaluate the status of the left ventricle in 32 patients with mitral stenosis, a modified form of supine leg exercise was done during simultaneous left and right heart ...

Although longitudinally directed fibres—situated mainly in the subepicardium and subendocardium regions of the left and right ventricular free walls and the papillary muscles—comprise only a small ...

A technic has been developed for determining the fraction of left ventricular end-diastolic volume that is ejected during each cardiac cycle. Radioiodinated Diodrast was rapidly injected into the left ...

Since the presence of LGE is often associated with nonsustained ventricular tachycardia ... walls), and detection of mitral valve and papillary muscle abnormalities for better risk stratification ...

Discussion Acute severe mitral regurgitation is a fatal complication of papillary muscle rupture and requires prompt diagnosis and urgent surgical intervention. Acute mitral regurgitation leads to a ...

Four standard views of the left ventricle were obtained for each acquisition: parasternal long axis, short axis at mitral and papillary muscle level, and apical four and two chamber views. After ...

Voluntary muscles, also known as skeletal muscles, are muscles that can be consciously controlled, such as the muscles of your limbs, head, neck, and body. They are attached to bones and respond to ...

No significant histological lesions were observed in the other organs evaluated. A. Canine, Border Collie, heart (case 3). White multifocal areas in the left ventricular myocardium, mainly in the ...

Minor muscle spasming can occur due to health conditions like nutrient deficiencies. More severe twitching can be a symptom of serious health conditions, including those affecting the nervous system.

Twenty participants were recruited. EMG signals from the left and right superior and posterior auricular muscles (SAM, PAM) were recorded while participants attended a target podcast in a competing ...
