The expression of sinus arrhythmia depends on separation of the systemic and pulmonary venous return to the heart as well as on normal autonomic control mechanisms. Patients with atrial septal defect provide a naturally occurring experiment of communication between the two venous systems. In adults with atrial septal defect sinus arrhythmia is minimal or absent. But children with atrial septal ...

INTRODUCTION It is unclear whether early restoration of sinus rhythm in patients with persistent atrial arrhythmias after catheter ablation of atrial fibrillation (AF) facilitates reverse atrial remodeling and promotes long-term maintenance of sinus rhythm. The purpose of this study was to determine the relationship between the time to restoration of sinus rhythm after a recurrence of an atrial...

Distinctive electrocardiographic patterns for atrial fibrillation, sinus rhythm and atrial extrasystoles, sinus arrhythmia and atrial flutter were found by analysing the frequency distribution of cycle lengths of the electrocardiogram. Frequency distribution analysis, demonstrated that atrial fibrillation is not completely irregular, but shows more long cycles than expected by chance and often ...

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 prediction oCcardiac attentional responses by respiratory sinus arrhythmia was tested in inCants at 14 and at 20 weeks oCage. Heart rate, heart rate variability, and respiratory sinus arrhythmia were measured in a 5-min baseline period. Respiration and heart rate responses were recorded during the habituation oCinfant visual attention. The level oCrespiratory sinus arrhythmia in the baselin...
