background: patients suffering from major beta thalassemia need frequent blood transfusions and, if not treated well, would be at risk of heart dysfunction. this study was performed to determine the diagnostic value of electrocardiography versus echocardiography in measuring the left ventricular mass index in these patients. methods: between july 2010 and june 2011, 82 asymptomatic patients ove...
electrocardiographic study of 50 healthy markhoz goats ranging from less than 1 to more than 3 years inage was carried out. the heart rate varied from 99 to 123 beats/min with a mean of 110 beats/min. there wasa significant difference between the heart rate of goats in 3 age groups (pt waves and qt interval in base apex lead, qrs wave in lead i, p-r and pq interval in avf lead were higherand du...
Electrocardiography has played an important role in the detection and characterization of heart function, both in normal and abnormal states. In this paper we present an inhomogeneous, anisotropic computer model of the human thorax for use in electrocardiography with emphasis on the calculation of transthoracic potential and current distributions. Knowledge of the current pathways in the thorax...
Cross sectional echocardiography, 12 lead electrocardiography, and 24 hour ambulatory electrocardiography were performed in eleven patients with tuberous sclerosis. Echocardiography showed single or multiple intramyocardial masses, most commonly in the ventricular septum, suggestive of rhabdomyomata in seven of the eleven cases. One patient with a normal echocardiogram showed ventricular pre-ex...
