electrocardiography (ecg) may be used to recognize cardiac disorders. levels of milk production may change the serum electrolytes which its imbalance has a role in cardiac arrhythmia. fifty high yielding and fifty low yielding holstein dairy cows were used in this study. electrocardiography was recorded by base-apex lead and blood samples were collected from jugular vein for measurement of seru...

repetitive episodes of brief regional ischemia have been shown to reduce the severity of life-threatening ventricular anhythrnias and infarct size that occur during prolonged occlusion of the coronary artery. this phenomenon is known as ischemic preconditioning. during studies in anesthetized, open chest wistar rats, we accidentally observed that poorly ventilated animals had a reduced severity...

introduction: this study was aimed to investigate the effects of postconditioning by natural honey on cardiac arrhythmias in the ischemic isolated rat heart. methods: male wistar rats were divided into four groups then anesthetized by sodium pentobarbital. the animal hearts were removed and quickly mounted on a langendorff apparatus and perfused under constant pressure by a modified krebs-hense...

Sofosbuvir is an antiviral drug that entirely revolutionized the treatment of hepatitis C. This drug has an Iranian commercial brand, which is known as Ledibiox. Several adverse events have been reported with this drug, including syncope, pancolitis, and exacerbated pulmonary arterial hypertension; however, arrhythmia rarely has been described through the literature. Here, we report a 40-year-o...

Background: Psoriasis is a prevalent chronic T cell mediated inflammatory skin disorder. Recent studies have reported an increase in the incidence of arrhythmia in psoriasis patients who run an excessive risk of metabolic syndrome and cardiovascular diseases. P-wave dispersion (PWD) and duration are important electrocardiographic (ECG) markers employed to anticipate the risk of atrial arrhythmi...
