The electrophysiologic changes associated with dysrhythmias induced by coronary occlusion and by subsequent reperfusion were characterized with six complimentary approaches in chloralose-anesthetized cats (n = 57) with proximal occlusion of the left anterior descending (LAD) coronary artery. Occlusion led to reproducible ventricular dysrhythmia which abated in 35 minutes. The electrophysiologic...

The aim of this study was to test experimentally the empirical existence of the following syndrome: aggressive behavior, brain dysrhythmia, and glucose imbalance. Only patients exhibiting the above participated in this study. Subjects were divided into four groups: the Experimental Croup consisting of treatment for the dysrhythmia and hypoglycemia, and the Hypoglycemia, the Brain Dysrhythmia, a...

Second, it is unclear why hypokalemia (75% of MIH cases) was dismissed as a factor for the incidence of cardiac dysrhythmia [1]. Temperature changes induce electrolyte shifts and thus influence the depolarization and repolarization times and the conduction velocity of action potentials within the myocardium, promoting aberrant conduction pathways. Electrolyte abnormalities associated with MIH c...

Bidirectional ventricular tachycardia is a rare dysrhythmia. It with morphologically diverse presentations. We report patient bidirectional secondary to fulminant myopericarditis.

this study describes the prevalence of cardiac dysrhythmias occurring over a single 24 h period in ponies and compares the heart rate and frequency of dysrhythmias in two groups of ponies of different ages. electrocardiograms were recorded using a holter monitoring system from twenty four ponies aged less than 15-year-old (n = 14) and greater than 15-year-old (n = 10). subsequent analyses of ca...

Thirty-three million people have atrial fibrillation (AF), a disorder of heart rhythm. Over the past several decades, we have learned that this dysrhythmia originates in the interplay between genetic predisposition, ectopic electrical activity, and abnormal atrial tissue substrate and then feeds back to remodel and worsen tissue substrate and, thereby, propagates itself. Although the importance...
