The electrocardiograms of 5000 healthy adult male applicants for aircrew training have been reviewed. Abnormalities were observed in the tracings of 158 subjects and these were further investigated. T-wave abnormalities occurred in 95 applicants, prolongation of the QRS (including the Wolff-Parkinson-White syndrome) in 28, prolongation of the P-R interval in 23, and miscellaneous changes in a g...
WE HAVE previously reported the successful transmission of electrocardiograms over telephone facilities using frequency modulation. Before seriously considering the possibility of transmitting electrocardiograms as a service it was necessary to determine whether or not acceptable transmissions could be uniformly obtained over message channels as they exist in the long distance telephone service...
The clinical and necropsy findings in 3 patients with tetralogy of Fallot who died suddenly after corrective operation are presented. Early postoperative electrocardiograms of 2 patients showed coexistent right bundle-branch block and left anterior hemiblock; one of these developed complete atrioventricular block and required a pacemaker. In the third a pacemaker. In the third patient, postoper...
Late-onset amyloidogenic transthyretin (ATTR) type familial amyloid polyneuropathy (FAP) shows features distinct from those of early-onset hereditary ATTR type FAP. We herein describe an asymptomatic 68-year-old man with late-onset ATTR type FAP whose serial annual electrocardiograms demonstrated progressive left bundle branch block. Latent but severe cardiac involvement seems to be one feature...
In this paper, rstly we have introduced to entropy of sequences of fuzzy sets and given sometheorems about it. Secondly, the waves P and T which appears in electrocardiograms weretransferred to fuzzy sets, by using denition of entropy for sequences of fuzzy sets, and somenumerical values were obtained for sequences of waves P and T. Thus any person can makea medical predictions for some cardiac...
