Electro-optic probing of electric fields has been considered as a promising approach for integrated circuit diagnosis. However, the method is subject to relatively weak voltage sensitivity. In this Letter, we solve the problems with electro-acoustic effect. In contrast to the general electro-optic effect, the light phase modulation induced by the acoustic effect is 2 orders of magnitude stronge...

This evening I shall lay before you the highly technical subject of electro-cardiology. It was by the invention of the string galvanometer by' W. Einthoven, a Dutch physiologist in 1901, that the study of the electrical variations associated with the activity of the various chambers of the heart was made possible. In Calcutta this subject has been introduced only lately, as the electro-cardiogr...

Both electro-encephalography and brain biopsy were examined as possible aids in the confirmation of a clinical diagnosis of heartwater in field cases. Results showed that electro-encephalographic changes associated with heartwater were non-specific and probably caused by the associated brain oedema. Brain biopsy on the other hand appears to be a reliable technique for the confirmation of heartw...

The application of temporary electro-stimulation is necessary in acute myocardial infarction complicated by the appearance of symptomatic bradycardia, AV conduction disturbances and asystolia. During the last two years, 38 of 892 patients (4.2%) with the diagnosis of acute myocardial infraction with ST segment elevation, required temporary electro-stimulation (27 with inferior infractions and 1...

We diagnosed an unusual case of Best's disease in a patient with multiple geographic macular and extramacular lesions. Initial confusion in the diagnosis arose because of a past history of intravenous drug abuse by the patient. The electro-oculogram was helpful in establishing the correct diagnosis.
