JOURNAL FREE ACCESSVarious kinds of vascular surgery for occlusive diseases of peripheral artery have become rather popular and fairly good results have been obtained. One of the most important factors influencing the results of operation is the condition of peripheral outflow tracts. Therefore, an arteriography extended to the very peripheral region is necessitated. Concerning the lower extremities. especially in the case with occlusive lesions, it is fairly difficult to have good visualization from the thigh down to the foot with usual methods. To dissolve this problem, the author tried to take the arteriography experimentally and clinically under the various conditions which were presumed to dilate arteries such as spinal anesthesia, sympathectomy, intra-arterial injection of Imidalin or Procaine and reactive hyperemia, and knew that we could have satisfactory results using the reactive hyperemia. Although it was quite possible that sympathectomy might promote the development of collaterals, the experimental proof was not yet sufficient. Applying the author's method, this problem has been dissolved experimentally. Arteriogram under the reactive hyperemia could be presumed to give the dynamic and functional interpretations. We have applied this new method upon many patients with various circulatory disturbances, and had several interesting findings. In this report, only the basic points are described.View full abstractDownload PDF (3647K) -

JOURNAL FREE ACCESSAlthough a QS or QR pattern in leads V3 and V4 is generally accepted as a diagnostic sign of myocardial infarction, similar patterns are also found in cases without infarction. Among 41 autopsied cases with significant Q waves in leads V3 and V4 there were 25 not associated with myocardial infarction. These electrocardiographic abnormalities were rather frequently observed at terminal stage and also in cases with severe pulmonary emphysema. It is difficult to decide whether myocardial infarction is present when significant Q waves persist without any other definite signs and symptoms, although the presence of coronary T wave in a precordial lead and/or marked left axis deviation is suggestive of infarction. The cause of significant Q waves in the absence of myocardial infarction was discussed and altered position of the heart was suggested to be responsible.View full abstractDownload PDF (1812K) -
MASAO IGARASHI1963 Volume 27 Issue 4 Pages 367-375

JOURNAL FREE ACCESSOne hundred and eighty electrocardiograms obtained from ninty hypopotassemic patients and fifty-eight normal adults were analyzed. Prolongation of the Q-Tc, depression of the ST segment, flattening or inversion of the T wave and prominence of the U wave were observed in hypopotassemic electrocardiograms. In acutely induced hypopotassemia as in familial periodic paralysis electrocardiogram seems to be a reliable guide in making a diagnosis of hypopotassemia. However, in chronically induced hypopotassemia nearly a half of electrocardiograms showed almost normal pattern. Metabolic alkalosis favors the development of hypopotassemic electrocardiographic manifestations.View full abstractDownload PDF (1163K)
