Four cases of complete right bundle-branch block and one case of atrioventricular heart block, all occurring within three generations of the same family, are described. The 4 patients with bundle-branch block had no symptoms, whereas the patient with atrioventricular heart block suffered Adams-Stokes attacks from the age of 13 and died at 47 years of age. A 33-year-old man with bundle-branch bl...

the present study was designed to assess the efficacy of fentanyl and pancuronium combined with dilute lidocaine solution for axillary block. onehundred adult patients undergoing upper limb surgery were randomly allocated to receive either 0.6 ml/kg of 1 % lidocaine (6 mg/kg) or 0.6 mllkg of 0.5% lidocaine (3 mg/kg) with 1 µg/kg of fentanyl and 0.5 mg of pancuronium. the onset of sensory and mo...

Let $mathbf{c}_0$ be the real vector space of all real sequences which converge to zero. For every $x,yin mathbf{c}_0$, it is said that $y$ is block diagonal majorized by $x$ (written $yprec_b x$) if there exists a block diagonal row stochastic matrix $R$ such that $y=Rx$. In this paper we find the possible structure of linear functions $T:mathbf{c}_0rightarrow mathbf{c}_0$ preserving $prec_b$.
