Using first atrial and then ventricular pacing, the cardiac rate was raised to 60% above control value. The effects of atrial and ventricular pacing were compared by observing the differences in the various parameters measured at corresponding paced heart rates. With atrial pacing there was no ...
Ventricular pacing for prevention of atrial fibril 优质文献 相似文献 参考文献 引证文献Right atrial preventive and antitachycardia pacing for prevention of paroxysmal atrial fibrillation in patients without bradycardia: a randomized study Aims To investigate the efficacy of preventive and antitachycardia pacing...
Left ventricular function was assessed by computer-assisted analysis of the motion of surgically implanted midwall myocardial tantalum markers, visualized fluoroscopically. Measurements were made at rest, and peak supine exercise in both groups of patients. The effect of atrial pacing to the heart ...

摘要: We have used pulsed Doppler to ascertain effective atrial contribution to ventricular filling in sequential pacemaker rhythm. The technique is particularly valuable when electrocardiographic evidence of atrial capture is uncertain.关键词:sequential pacing pulsed Doppler atrial contraction P wave ...
Aims For patients with refractory atrial fibrillation (AF) undergoing atrioventricular nodal ablation (AVNA), initial single-chamber right ventricular (RV)-only pacing is standard. Given the deleterious effects of chronic RV-only pacing, the impact of an initial biventricular (BiV) pacing strategy ...
5) Right ventricular apical pacing 右室心尖部起搏 1. Objective To find a forecasting index of left cardiac structure and function in patients with right ventricular apical pacing. 目的探讨右室心尖部起搏QRS波时限在左室结构及功能评价中的价值。
Objective = 2.8, = .048), but there was no difference in cardiac output during pacing at the minimum possible rate and the corresponding preceding cycle length in AF. Conclusion Our data suggest that regularization of ventricular rhythm by overdrive pacing in patients with AF only improves stroke...
In total, BP monitoring yielded 497 false-positive screens, of which 39.2% were associated with frequent atrial or ventricular premature complexes (>60/h) on cECG monitoring. The median AF duration among patients with a true-positive AF screen by BP monitoring was 15.8 hours; the median AF ...
Furthermore, we investigated effects of percentage of ventricular pacing (%VP) and pacing site in the ventricle.We analysed data from 1415 patients randomized to AAIR (n = 707) or DDDR pacing (n = 708). Ventricular pacing leads were recorded as located in either an apical or a non-...
