Sex differences in the vectorcardiogram.
In a study of 101 normal men and 102 normal women (mean age, 42.5 and 42.6 years, respectively), significant sex differences were observed in 43 of 64 vectorial items analyzed (initial 0.02-sec and 0.025-sec vectors, maximal QRS and T vectors, terminal 0.02-sec vectors in frontal, horizontal left sagittal planes; Q, R, S, and T deflections in Frank's X, Y, and Z leads). The initial QRS vectors ...
متن کاملThe Corrected Orthogonal Electrocardiogram and Vectorcardiogram in 510 Normal Men (frank Lead System).
A NUMBER of reports on normal ranges of corrected orthogonal electrocardiographic measurements have appeared in the literature.'-12 They were derived, however, from limited numbers of subjects and the types of electrocardiographic and vectorcardiographic measurements varied largely from one study to another. The reported results are therefore not always strictly comparable. In spite of these li...

متن کاملThe Frank vectorcardiogram in normal men. Norms derived from visual and manual measurement of 300 records.
Broad clinical application of vectorcardiography has been limited by the lack of a single, widely accepted recording system and the paucity of firmly established diagnostic norms. Most clinical reports and texts, therefore, have used the vectorcardiogram primarily for vivid pictorial display of typical abnormalities. A recent co-operative study, in which interpretation of the vectorcardiogram b...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
