the use of diagnostic and therapeutic methods for assessing pulmonary vein due to its status as a main source of ectopic beats for the initiation of atrial dysrrythmias is strongly recommended.   we report the case of a 13-year-old girl who was admitted to our hospital with the electrocardiogram manifestation of an ectopic atrial tachycardia. the focus of arrhythmia was inside the right upper p...

background: this study was conducted to reveal that whether i.v. injection of oleuropein, the most potent polyphenolic antioxidant in olive leaf, has any effect on the magnitude of reperfusion arrhythmia in anesthetized rats or not. methods: eighty male wistar rats were divided into 8 groups of 10 each: groups 1 and 5 were assigned as the prophylactic and treatment control groups, groups 2 and ...

the effect of opium addiction on the appearance of different types of arrhythmias after acute myocardial infarction (ami) has been assessed in few studies. this study is aimed to determine the effect of opium on post-mi arrhythmia and also to address the differences in the appearance of different types of arrhythmias after ami between opium addicted and non-addicted patients. in this comparativ...

objective(s) in this study, effects of chronic administration of oral natural honey against ischemia/reperfusion (i/r)-  induced cardiac arrhythmias were investigated in isolated rat heart. materials and methods male wistar rats were divided into four groups (n= 10-14 rats in each group) and fed with natural honey (1%, 2% and 4% dissolved in the drinking water) for 45 days except for the contro...

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) ...

Cardiac arrhythmias, caused by disorders in the generation and transmission of cardiac impulses, is included among the heart disorders that cause inefficient blood circulation. The most commonly-used method for diagnosing this disorder is electrocardiography. In this study, we aimed to identify and diagnose different types of arrhythmia prevalent among the seemingly-healthy horses of Sanandaj C...
