and others,Hurst's The Heart 8th Edition,The Resting Electrocardiogram,321-356. Complete LBBB This conduction disturbance is characterized by wide (greater than 0.11s) QRS complexes. The diagnostic criteria consist of prolongation of the QRS complexes (over 0.11s) with neither a q wave nor an...
Air conduction by tympanic membrane, auditory ossicles and oval window
Similarly, sudden loss of the delta wave during exercise [2] is also considered evidence of prolonged refractoriness over an accessory A-V pathway. However, the antegrade refractory period of an accessory A-V pathway is not the only determinant of conduction over bypass tracts. Two other ...
dog heartWe studied the effects of selective and combined ablation of the fast (FP) and slow pathway (SP) on AV and VA conduction in the normal dog heart using a novel epicardial ablation technique. For FP ablation, radiofrequency current (RFC) was applied to a catheter tip that was held...
Heterogeneous Expression of Gap Junction Channels in the Heart Leads to Conduction Defects and Ventricular Dysfunction Optical mapping of chimeric hearts by use of voltage-sensitive dyes revealed highly irregular epicardial conduction patterns, quantified as significantly greater ...

We found that RNR inactivation in heart led to strongly decreased dGTP and increased dCTP, dTTP, and dATP pools; aberrant DNA replication; defective expression of muscle-specific proteins; progressive heart abnormalities; disturbance of the cardiac conduction system; and lethality between the second ...
[48]The clinical effects of aerobic exercise extend beyond that of biomarkers. Balducci et al. were the first to report that 4 hours of weekly exercise at 50% to 85% of maximum heart rate had the potential to improve vibration detection and nerve conduction study indices in...
Impairment of the auriculoventricular conduction time was studied in twenty-two patients with acute rheumatic fever. Observations were made (1) after the intravenous injection of atropine sulphate, (2) during a period of acute emotional ... H Bruenn - 《American Heart Journal》 被引量: 11发表...
capability may be responsible for manifest, intermittent, or non-manifest ventricular pre-excitation depending on whether it is respectively always visible on the ECG, not always visible on the ECG and not visible on the ECG even though the p...
