We have introduced echocardiography into the physiology courses for medical students to improve their understanding of cardiac physiology. Echocardiography allows a visualization of the events of the cardiac cycle and facilitates the correlation of anatomic structures with their physiological functions. The students record views on the human heart in the long and short axis, they follow wall an...

Introduction: Hearing impairment is the most frequent sensorial congenital defect in newborns and has increased to 2–4 cases per 1,000 live births. Sensory-neural hearing loss (SNHL) accounts for more than 90% of all hearing loss. This disorder is associated with other congenital disorders such as renal, skeletal, ocular, and cardiac disorders. Given that congenital heart diseases are life-thre...

BACKGROUND The signal-averaged electrocardiography is a noninvasive method to evaluate the presence of the potentials generated by tissues activated later than their usual timing in the cardiac cycle. The purpose of this study was to demonstrate the correlation between the filtered QRS duration obtained via the signal-averaged electrocardiography and left ventricular dimensions and volumes and ...

Background: Thalassemia is one of the common inherited blood disorders and Beta Major a homozygous form deficiency beta globin chain synthesis causing severe transfusion-dependent anemia, manifesting between 6 24 months life. Objectives: The objective study to pattern cardiac function in children adolescents with beta-thalassemia major by 2D Echocardiography its correlation serum ferritin level...

A 70-year-old man with history of previous myocardial infarction was referred for cardiac resynchronization therapy (CRT) implantation. Echocardiography showed global wall motion abnormality and non-viable myocardium with ejection fraction of 15% and large apical aneurysm. Electrocardiography (ECG) revealed sinus rhythm with wide QRS (200 ms). Of note is the finding of marked fragmentation of Q...

OBJECTIVE To evaluate the discriminatory value and compare the predictive performance of six non-invasive tests used for perioperative cardiac risk stratification in patients undergoing major vascular surgery. DESIGN Meta-analysis of published reports. METHODS Eight studies on ambulatory electrocardiography, seven on exercise electrocardiography, eight on radionuclide ventriculography, 23 o...

We introduce a 28-year-old woman with Thalassemia major whose clinical assessment, including two-dimensional Doppler echocardiography demonstrated severe left ventricular hypertrophy with severe biventricular enlargement and systolic dysfunction as well as severe diastolic dysfunction. We hereby address these issues from an echocardiographic point of view.

Methods A group of patients with mitral regurgitation underwent electrocardiography, chest teleradiography, venous blood withdrawal, and transthoracic echocardiography. Based on an analysis of the echocardiographic variables, 62 patients had mild and moderate mitral regurgitation (GI) and 34 had severe mitral regurgitation (GII). The discriminating capacity of the BNP for detecting patients wit...

The detection and characterization of transient arrhythmias is possible with continuous ambulatory electrocardiography (Holter monitoring) or cardiac event recording. These techniques have significantly increased our appreciation of transient arrhythmias, often undetected with routine echocardiography and have provided highly sensitive means to assess need and efficacy of antiarrhythmic therapy...

We report an 82-day-old infant with a rare combination of anomalies: pulmonary atresia associated with corrected transposition of the great arteries and intact ventricular septum; this is the second such recorded case. By using echocardiography, chest radiography, and electrocardiography the correct anatomical diagnosis was obtained before invasive investigation and necropsy.
