It has been demonstrated repeatedly that not much importance c attached to the prognostic significance of bundle branch block. Right I branch block has been considered to show a more favorable proj than left bundle branch block. However, the presence of right I branch block, either the typical or atypical form, alerts the physici the basic cardiac disease, particularly disease of the coronary c...

When a patient is suspected of having Stokes-Adams disease the electrocardiogram is of critical importance, particularly in respect of the auriculo-ventricular (A-V) conduction time. Should this not be prolonged, the possibility of paroxysmal heart block remains, although the diagnosis of Stokes-Adams disease is uncertain without some degree of heart block recorded graphically. It is not known ...

conclusions right ventricular pacing increases the qt interval without increasing the jt interval. our results confirm that jtc, as an index of repolarization, is independent of ventricular depolarization. therefore, it can be applied for predicting qtc in patients with lbbb. results stimulation from the rva increased the qtc from 456.20 ± 38.63 ms to 530.67 ± 47.73 ms at a cl of 600 (p < 0.000...

The aim of this study was to compare the mid-term effects and benefits of ultrasound (US)-guided and fluoroscopy (FL)-guided medial branch blocks (MBBs) for chronic lower lumbar facet joint pain through pain relief, functional improvement, and injection efficiency evaluation.Patients with chronic lumbar facet joint pain who received US (n = 68) or FL-guided MBBs (n = 78) were included in this r...

Objective: The aim of this cross-sectional study was to evaluate the outcome of a medial branch block (MBB) in elderly patients to determine the factors associated with the degree of pain relief. Methods: Fifty-six patients 75 years or older with MBB from January 2013 to July 2015 were classified into two groups by the degree of pain relief. The outcome of the MBB was evaluated according to cli...

In five cases of anteroseptal myocardial infarction complicated by intermittent right bundle-branch block, the onset of right bundle-branch block provoked the appearance of abnormal Q waves in leads V1 and V2, whereas a small initial R wave was present in the same leads during normal conduction. The intermittency of the conduction disturbance indicated that the Q waves were "right bundle-branch...
