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 ]
Another, non-obstructive variant of HCM is apical hypertrophic cardiomyopathy (AHCM or ApHCM), [37] also called Yamaguchi syndrome. It was first described in individuals of Japanese descent. Sakamoto is the first to report the condition's ECG pattern in 1976.
Left ventricular hypertrophy with secondary repolarization abnormalities as seen on ECG Histopathology of (a) normal myocardium and (b) myocardial hypertrophy. Scale bar indicates 50 μm. Gross pathology of left ventricular hypertrophy. Left ventricle is at right in image, serially sectioned from apex to near base.
Electrocardiogram (EKG), a non-invasive assessment of the electrical system of the heart, can be useful in determining the degree of hypertrophy, as well as subsequent dysfunction it may precipitate. Specifically, an increase in Q wave size, abnormalities in the P wave , as well as giant inverted T waves , are indicative of significant ...
Anticoagulants: To prevent embolization.. Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate.. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
ECG beat. The Pan–Tompkins algorithm [1] is commonly used to detect QRS complexes in electrocardiographic signals ().The QRS complex represents the ventricular depolarization and the main spike visible in an ECG signal (see figure).
The typical presentation of takotsubo cardiomyopathy is chest pain with or without shortness of breath and associated electrocardiogram (ECG) changes mimicking a myocardial infarction of the anterior wall. During the course of evaluation of the patient, a bulging out of the left ventricular apex with a hypercontractile base of the left ...
Electrical alternans is an electrocardiographic phenomenon of alternation of QRS complex amplitude or axis between beats and a possible wandering base-line. It can be seen in cardiac tamponade and severe pericardial effusion and is thought to be related to changes in the ventricular electrical axis due to fluid in the pericardium, as the heart essentially wobbles in the fluid filled ...
