Abstract: The present invention relates to a biologic apparatus that permits easy and quick telephonic transmission of biologic signals--such as an electrocardiogram, blood pressure, cranial waveforms, and the like--from any location having a telephone handset. The disclosed apparatus is so simple to use that, if necessary, an inexperienced person can perform the entire procedure.The disclosed apparatus comprises a single, small, lightweight unit that may be carried unobtrusively in a purse, a handbag, a brief case, an attache case, or the like; and may be put into use at any location having a telephone handset.It does not require cardiac-gel, and may therefore be used as often as necessary without causing skin problems. Furthermore, it obviates "hard-wiring" between the patient and the apparatus; so that there is no danger of pulling off electrodes.
