A fairly accurate estimate of the target heart rate, based on extensive clinical research, can be estimated by the formula 220 beats per minute minus patient's age. This linear relation is accurate up to about age 30, after which it mildly underestimates typical maximum attainable heart rates achievable by healthy individuals.
Strain rate imaging is a method in echocardiography (medical ultrasound) for measuring regional or global deformation of the myocardium (heart muscle). The term "deformation" refers to the myocardium changing shape and dimensions during the cardiac cycle.
The training required to become an electrophysiologist is lengthy and requires eight years after medical school (in the U.S.), entailing three years of internal medicine residency, three years of clinical cardiology fellowship, and two years of clinical cardiac electrophysiology. This is necessary due to the significant complexity of patients ...
Match Day for the NRMP Main Residency Match is on the third Friday of March each year, and Match Day ceremonies occur at many of the 155 medical schools in the United States where those results are announced. Match Days for the NRMP Fellowship Matches occur throughout the year because each Fellowship Match has its own schedule of dates.
The National Resident Matching Program (NRMP), also called The Match, [1] is a United States–based private non-profit non-governmental organization created in 1952 to place U.S. medical school students into residency training programs located in United States teaching hospitals. Its mission has since expanded to include the placement of U.S ...
In cardiology, aortic valve area calculation is an indirect method of determining the area of the aortic valve of the heart. The calculated aortic valve orifice area is currently one of the measures for evaluating the severity of aortic stenosis. A valve area of less than 1.0 cm 2 is considered to be severe aortic stenosis. [1] [2]
The American Registry for Diagnostic Medical Sonography (ARDMS), incorporated in June 1975, is an independent nonprofit organization that administers examinations and awards credentials in the areas of diagnostic medical sonography, diagnostic cardiac sonography, vascular technology, physicians’ vascular interpretation, musculoskeletal sonography and midwifery ultrasound.
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 ...
