Electrocardiographic findings in patients with obstructive and nonobstructive hypertrophic cardiomyopathy.
One hundred and thiry-four patients with hypertrophic cardiomyopathy were evaluated by standard 12-lead electrocardiography. Normal electrocardiograms were extremely uncommon, occurring in less than 7% of each subgroup of patients (i.e., those with or without either symptoms or obstruction to left ventricular outflow), with the exception of those who were both asymptomatic and had no left ventr...
متن کاملMyocardial shortening in 3 orthogonal directions and its transmural variation in patients with nonobstructive hypertrophic cardiomyopathy.
BACKGROUND Although longitudinal strain (LS) is known to be reduced in patients with hypertrophic cardiomyopathy (HCM), it has not been elucidated whether or not circumferential strain (CS) is reduced. We aimed to determine whether multidirectional and layer-specific myocardial strain is reduced in patients with nonobstructive HCM. METHODSANDRESULTS Speckle-tracking echocardiography was perfo...
متن کاملMyocardial fibrosis delineation in late gadolinium enhancement images of Hypertrophic Cardiomyopathy patients using deep learning methods
Introduction: Accurate delineation of myocardial fibrosis in Late Gadolinium Enhancement on Cardiac Magnetic Resonance (LGE-CMR) has a crucial role in the assessment and risk stratification of HCM patients. As this is time-consuming and requires expertise, automation can be essential in accelerating this process. This study aims to use Unet-based deep learning methods to automate the mentioned ...

Rev Esp Cardiol. 2005;58(5):585-6 585 A 20-year-old man was referred to our myocardial disease unit for family screening. His father presented obstructive hypertrophic cardiomyopathy and had an automatic defibrillator implanted for sustained ventricular tachycardia. His brother had died of sudden death at the age of 12. The patient only reported dyspnea on exertion. In the electrocardiogram (EC...
متن کاملMyocardial dysfunction in hypertrophic cardiomyopathy.
Cardiomyopathy To The Editor: We note with interest Nagueh et al’s1 recent observation that the reduction of tissue Doppler (TD) velocities in mitral annulus excursion was highly sensitive and specific for the detection of individuals carrying hypertrophic cardiomyopathy (HCM)–causing mutations in HCM families, even in the prehypertrophic phase. Any clinical tool that can reliably identify subt...
