abstract objective cardiac dysfunction is a major cause of death in patients with beta thalassemia. in these patients, repeated blood transfusion, ineffective erythropoiesis and increased gastrointestinal iron absorption lead to iron overload in the body and this induced heart failure. left ventricular ejection fraction was measured in major beta thalassemia (β-th) patients to detect the relati...

a 47-year-old man presented as a dyspnea and fatigue. a transthoracic echocardi-ography (tte) performed to assess valvar heart disease and left ventricular (lv) function showed a large hydatid cysts in the inter ventricular septum bulging to posterior of heart and compressing its overlying muscle as whitish round mass. the patient underwent elective surgery by evacuation of septal hydatid cysts...

background: nt-probnp is a marker that is released from ventricles in response to pressure and volume overload. raised plasma level of nt-probnp is seen in ventricular dysfunction, ventricular muscular mass reduction or ventricular ischemia. anthracyclines are widely used in treatment of pediatric cancer but their use is associated with cardiotoxicity which increases mortality and morbidity. we...

background: assessment of myocardial function is essential in heart disease, but in regard to systolic and diastolic functions such evaluation has limitation. ejection fraction is difficult to assess in abnormally-shaped ventricles, and diastolic inflow velocity pattern may be fused because of tachycardia.   objective: a myocardial performance index (mpi) or tei index has been developed for adu...

This study evaluates the discriminative power of sequential spectrum analysis of the short-term electrocardiogram (ECG) time series in separating normal and subjects with life threatening arrhythmias like, ventricular tachycardia/fibrillation (VT/VF). The raw ECG time series is transformed into a series of binary symbols and the binary occupancy or relative distribution of mono-sequences (i.e. ...

In this study, it was surveyed to know whether an oral single dose of oleuropein could mimic the cardiac preconditioning in rats’ hearts or whether its prolonged oral administration could protect the heart against the aconitine-induced arrhythmia in rats. Eighty male Wistar rats were divided into two series (n = 8 in each group). In the first series, all groups (except the control (Con) group) ...

Since the introduction of our local manufacturing of terfenadine, we have observed and expressed our concern about a small but increasing number of serious ventricular arrhythmias associated with the use of this non sedating antihistamine. In January 1997 a case of torsade de pointes ventricular tachycardia was detected in a previously healthy woman taking terfenadine with erythromycin. El...

Breed-wise standard echocardiographic values in dogs have been reported as there is variation in body and chest conformation which limits the application of data of one breed for other breed. Labrador Retrievers being originated from hunting dogs, might have different echocardiographic values from standard normal range of other dog breeds. So, the present study was aimed to determine the M-mode...
