effects of doxycycline on cx43 distribution and cardiac arrhythmia susceptibility of rats after myocardial infarction abstract: this study aimed to observe the effects of doxycycline (dox) on gap junction remodeling after mi and the susceptibility of rats to cardiac arrhythmia. the proximal left anterior descending coronary artery of rats was ligated to establish a myocardial infarction animal ...

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...

background: there are some reports on the association between air pollution and myocardial infarction, arrhythmia, and mortality due to cardiac problems in susceptible individuals. we aimed to evaluate the association of air pollution and the emergency visits due to cardiovascular diseases, in a specialized heart hospital in tehran. methods: the study design was cross-sectional. patients admitt...

av-node modification by catheter rf energy delivery is treatment of choice in the symptomatic patients with avnrt. this study included 30 patients with avnrt (19 women, 11 men). we did slow pathway ablation in 29 cases successfully. maximum effective energy delivery was 40 watts for 40 msec. 1:1 av conduction increased from 290±40 msec before ablation to 340±65 msec after ablation. also av-node...

Persistent atrial fibrillation is one of the most common arrhythmias, which is caused by disorderly excited and invalid contract room sex rhythm in patients with arrhythmia. Evidences have indicated that plasma concentration levels of bilirubin and serum uric acid are associated with progression of auricular fibrillation. In this clinical investigation, regression analysis between auricular fib...

The aim of this study was to analyze the incidence and types of arrhythmia and their relationship with the severity and prognosis of chronic heart failure (CHF) in patients with dilated cardiomyopathy (DCM), and to investigate the therapeutic effect of torasemide versus furosemide on CHF and incidence of arrhythmia. DCM patients with NYHA cardiac function II-IV were continuously monitored using...
