Two patients who developed left bundle-branch block with increase in heart rate are presented. Atrial pacing during His bundle recording studies showed differing responses in the ventricular specialized conduction system of the two patients. In one, the onset of left bundle-branch block was associated with no change in the previously normal HVinterval (so msec), while in the second the HV inter...

This study had two purposes: first, to determine how femoral attachment location affects the load sharing between the two bundles of a Y-type posterior cruciate ligament reconstruction, and second, to determine how the bundles, separately and in combination, control posterior tibial translation throughout the full range of knee flexion. One and two-bundle reconstructions were performed in 12 ca...

Paced QRS morphology should be assessed to differentiate between complete loss of His bundle capture and loss of distal His bundle capture alone. This might be enough in patients with proximal right bundle branch block; however, in patients with proximal left bundle branch block, QRS morphology might be similar with loss of His bundle capture and with proximal His bundle capture. Introduction T...

Data presented in this article relates to the research article entitled "Association between QRS duration on prehospital ECG and mortality in patients with suspected STEMI" (Hansen et al., in press) [1]. Data on the prognostic effect of automatically recoded QRS duration on prehospital ECG and presence of classic left and right bundle branch block in 1777 consecutive patients with confirmed ST ...

Analysis of I6 cases with intermittent bundle-branch block showing rate-dependence revealed the presence of 12 instances with tachycardia-dependent bundle-branch block, 3 with bradycardiadependent bundle-branch block, and one instance showing both types at two different occasions. Tachycardia-dependent bundle-branch block was explained on the basis of cycle length-recovery time relation and rev...

We make the category BGrb M of bundle gerbes on a manifold M into a 2-category by providing 2-cells in the form of transformations of bundle gerbe morphisms. This description of BGrb M as a 2-category is used to define the notion of a bundle 2-gerbe. To every bundle 2-gerbe on M is associated a class in H 4 (M ; Z). We define the notion of a bundle 2-gerbe connection and show how this leads to ...

everal investigators1-3 have recorded His bundle activity in patients with left axis deviation and right bundle branch block (RBBB), using the catheter method Scherlag et a1 described in 1969.4 According to the concepts of trifascicular conduct i ~ n , ~ conduction delay or block in the right bundle branch (RBB) and anterosuperior division of the left bundle branch (LBB) is responsible for this...

Atrial fibrillation is one of the most frequent arrhythmias diagnosed in clinical practice and it is also relatively common in dialysis patients. Atrioventricular and intraventricular conduction disturbances are less investigated in hemodialysis patients and data about their prevalence are insufficient. The objective of this study was to determine the prevalence of atrial fibrillation, atrioven...
