Left ventricular hypertrophy and hypertrophic cardiomyopathy.
eft ventricular myocardial hypertrophy (LVH) occurs in any conditions, usually, it is thought, as a secondary or compensatory” response to abnormal pressure or volume oading and to stimuli, as yet incompletely understood, esulting from deficiencies in cardiac performance (1). hese responses may be modulated by genetic predisposiions, a relationship also not well understood. “Compensaory” hypert...
متن کاملAssociation between high grade ventricular arrhythmia and extent of left ventricular hypertrophy in hypertrophic cardiomyopathy.
The association between the extent of left ventricular (LV) hypertrophy and severity of ventricular or atrial arrhythmias are examined. Two-dimensional echocardiography and 24-h Holter electrocardiography monitoring were performed in 60 patients with hypertrophic cardiomyopathy (HCM). According to the distribution of the LV hypertrophy, the patients were divided into three groups: 1. Apical hyp...
متن کاملVentricular arrhythmias and left ventricular hypertrophy in hypertrophic cardiomyopathy.
BACKGROUND In hypertrophic cardiomyopathy (HCM), the degree of left ventricular hypertrophy (LVH) could influence the development of ventricular arrhythmias. OBJECTIVE In HCM, analyze the association between the occurrence of ventricular arrhythmias determined by Holter electrocardiogram (ECG-Holter) and the degree of LVH determined by maximum wall thickness (MWT) in echocardiography and body...
متن کاملDiastolic abnormalities in patients with hypertrophic cardiomyopathy: relation to magnitude of left ventricular hypertrophy.
To investigate the relationship between diastolic abnormalities and left ventricular hypertrophy, 52 patients with hypertrophic cardiomyopathy (HCM) and 22 normal subjects were studied with digitized M mode echocardiography and two-dimensional echocardiography. Echocardiographic indexes of diastolic function were compared in patients with different extent of left ventricular hypertrophy. Time i...
متن کاملEndomyocardial radial strain imaging and left ventricular relaxation abnormalities in patients with hypertrophic cardiomyopathy or hypertensive left ventricular hypertrophy.
BACKGROUND Asymmetrical septal hypertrophy and impaired left ventricular (LV) diastolic function are common echocardiographic features of hypertrophic cardiomyopathy (HCM). However, it is difficult to differentiate nonobstructive HCM from hypertensive LV hypertrophy (H-LVH). METHODS AND RESULTS Standard echocardiography and tissue Doppler imaging were performed in 14 patients with HCM, 16 pat...
