Hypertrophic cardiomyopathy (HCM, or HOCM when obstructive) is a condition in which muscle tissues of the heart become thickened without an obvious cause. [8] The parts of the heart most commonly affected are the interventricular septum and the ventricles . [ 10 ]
Hypertrophic cardiomyopathy screening is an assessment and testing to detect hypertrophic cardiomyopathy (HCM). [ 1 ] [ 2 ] It is a way of identifying HCM in immediate relatives of family members diagnosed with HCM, and athletes as part of a sports medical . [ 3 ]
A split S2 is a finding upon auscultation of the S2 heart sound. [1] It is caused when the closure of the aortic valve (A 2) and the closure of the pulmonary valve (P 2) are not synchronized during inspiration. The second heart sound (S2) is caused by the closure of the aortic and pulmonic valves, which causes vibration of the valve leaflets ...
According to one study, it has a sensitivity of 65% and specificity of 96% in HOCM. [11] Valsalva maneuver, as well as standing, decrease venous return to the heart. As a result, this decreases left ventricular filling. With HOCM, the outflow obstruction increases with a decrease in preload. This will increase the loudness of the murmur with ...
An electrocardiogram (ECG or EKG) may be used to identify arrhythmias, ischemic heart disease, right and left ventricular hypertrophy, and presence of conduction delay or abnormalities (e.g. left bundle branch block). Although these findings are not specific to the diagnosis of heart failure, a normal ECG virtually excludes left ventricular ...
Wiggers diagram with mechanical (echo), electrical (ECG), and aortic pressure (catheter) waveforms, together with an in-ear dynamic pressure waveform measured using a novel infrasonic hemodynography technology, for a patient with severe aortic stenosis.
The side-gig industry is still booming, but not all side gigs are created equal and not all people doing them make enough money to justify the time and effort involved. According to Self, just ...
People who have a normal ECG and who are able to exercise, for example, do not merit routine imaging. [13] Imaging tests such as stress radionuclide myocardial perfusion imaging or stress echocardiography can confirm a diagnosis when a person's history, physical exam, ECG and cardiac biomarkers suggest the likelihood of a problem.
