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.
The diagnosis of left ventricular outflow tract obstruction is usually made by echocardiographic assessment and is defined as a peak left ventricular outflow tract gradient of ≥ 30 mmHg. [35] Another, non-obstructive variant of HCM is apical hypertrophic cardiomyopathy (AHCM or ApHCM), [37] also called Yamaguchi syndrome.
In electrocardiography, a strain pattern is a well-recognized marker for the presence of anatomic left ventricular hypertrophy (LVH) in the form of ST depression and T wave inversion on a resting ECG. [1] It is an abnormality of repolarization and it has been associated with an adverse prognosis in a variety heart disease patients.
Ventricular hypertrophy can result from a variety of conditions, both adaptive and maladaptive. For example, it occurs in what is regarded as a physiologic, adaptive process in pregnancy in response to increased blood volume; but can also occur as a consequence of ventricular remodeling following a heart attack .
An unusually tall QRS complex may represent left ventricular hypertrophy while a very low-amplitude QRS complex may represent a pericardial effusion or infiltrative myocardial disease. 80 to 100 ms J-point: The J-point is the point at which the QRS complex finishes and the ST segment begins. The J-point may be elevated as a normal variant.
This delays the onset of the intrinsicoid deflection. This prolongation or delay is an important criterion for diagnosing bundle branch block or ventricular hypertrophy. Time of onset of intrinsicoid deflection > 0.04 seconds (just over one small box) is used as a non-voltage related criterion to diagnose left ventricular hypertrophy. [2]
