The palpation of dilated myopathy differs in that the impulse tends to be vigorous and brief. This is in contrast with the sustained impulse of the hypertrophied right ventricle. [5] A parasternal heave may also be felt in mitral stenosis. [6] A left ventricular heave (or lift) suggests the possibility of aortic stenosis. [citation needed]
Published normal ranges for LVMi are 49–115 g/m 2 for men and 43–95 g/m 2 for women. [1] [4] left ventricular hypertrophy (LVH) is defined as an abnormal increase in LVM, an important independent risk factor for cardiovascular morbidity and mortality.
Left ventricular mass can be further estimated based on geometric assumptions of ventricular shape using the measured wall thickness and internal diameter. [7] Average thickness of the left ventricle, with numbers given as 95% prediction interval for the short axis images at the mid-cavity level are: [8] Women: 4 – 8 mm; Men: 5 – 9 mm
Echocardiography can be used to directly visualise right ventricular wall thickness. The preferred technique is the trans-oesophageal approach giving a view of 4 chambers. The normal thickness of a right ventricular free wall ranges from 2-5 millimetres, with a value above 5 mm considered to be hypertrophic. [10]
Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
There are two atrial and two ventricle chambers of the heart; they are paired as the left heart and the right heart—that is, the left atrium with the left ventricle, the right atrium with the right ventricle—and they work in concert to repeat the cardiac cycle continuously (see cycle diagram at right margin).

While 37 °C (99 °F) is considered "normal" body temperature, there is some variance between individuals. Most have a normal body temperature set point that falls within the range of 36.0 to 37.5 °C (96.8 to 99.5 °F). [13]
