I am concerned about the implications of the Editorial by Drs. Lown and Axelrod which appeared in the October 1972 issue of Circulation. Although the authors rightfully point out the numerous technical problems still to be overcome in the development of such defibrillators, their conclusions in the last three paragraphs indicate a heavy bias in favor of "practical research." Although Dr. Lown h...

Three patients with complete heart block had a high resistance to electrical stimulation of the endocardium through transvenous pacemaker systems. One patient died; one needed reoperation for implantation of epicardial electrodes; and the third required a generator of higher current. The present enthusiasm for permanent transvenous implantation of pacemakers must be tempered somewhat by the kno...

objectives: profound hearing loss encounters children with delay in speech and language. as it is known language acquisition in young deaf children is a lengthy process, but cochlear implanted children have better spoken language skills than if they had not received the device. according to the importance of cochlear implant in deaf child's language development, this study evaluates the ef...
