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...

The occurrence of dysrhythmias after the Mustard operation for transposition of the great arteries was compared in 70 patients operated upon before and 58 patients operated upon after January 1972 when surgical modifications aimed at preserving the sino-atrial node and its arterial supply were initiated. The surgical modifications included changing the site of the superior vena cava (SVC) cannu...

THE VAST majority of deaths associated with myocardial infarction occur within the first few hours of the acute attack and are secondary to ventricular dysrhythmias evolving to ventricular fibrillation. Although the precise mechanisms responsible for these lethal dysrhythmias remain elusive, a large body of data indicates that profound alterations in autonomic nervous system function occur duri...

Reports of sudden unexpected death in pediatric patients taking selected psychotropic drugs have raised the possibility of ventricular dysrhythmias as the cause of these deaths. The use of psychotropic drugs in the pediatric population has increased significantly in recent years with increasing reports of electrocardiogram abnormalities, particularly prolongation of the corrected QT interval. M...

This study was conducted on 384 clinically healthy sheep and goats from farms around Tehran suburb. The animals were divided into two equal groups (according to species) and then assigned into three age groups, two gender groups and female animals into two groups: late pregnant and non-pregnant. Heart sounds were auscultated by two cardiologists and heart rate and probable murmurs were recorded...

background: cardiovascular system is a very importantorgan that plays a vital role in tissue function. in farm animals,the growth and high milk production depends on function ofcardiovascular system. objectives: cardiovascular health inhigh and low-yielding dairy cows was investigated. methods:fifty 4-year-old high- yielding holstein dairy cows and fifty 4-year-old low- yielding holstein dairy ...

This review describes recent advances in our knowledge about the pathogenesis and therapeutic approaches to human gastric dysrhythmias. A number of clinical conditions has been found to be associated with gastric slow-wave rhythm disturbances that may relate to the induction of nausea and vomiting. Human and animal studies indicate that multiple neurohumoral factors are involved in the generati...

First trimester nausea is associated with gastric slow wave dysrhythmias (tachygastria, bradygastria). We tested the roles of meal composition and caloric content on nausea and slow wave rhythm in 14 nauseated pregnant women. Electrogastrography quantified dysrhythmic activity and signal power responses to meals. Symptomatic women reported mild to moderate nausea and exhibited increased dysrhyt...

In the past 30 years mortality in acute myocardial infarction had remained virtually unchanged, varying between 30 and 40 per cent. Recently, with the advent of the coronary care unit, it has become possible to increase the patient's chance of survival, partly by the more energetic treatment of cardiogenic shock, but largely by the prompt suppression of the minor dysrhythmias which are such a c...
