For the first time in 1921, it was used as a lie detector.
Therefore, the etymology of the polygraph originated from polys “much, many” and “Graphos” writing.īut as a term, the polygraph is a device to record the alternations of distinct pulsations simultaneously. The word polygraph is literally derived from the Greek word “Polygraphos” meaning writing much. In the end, you will get familiar with the polygraph usage in different agencies and the benefits of using it. Then, it talks about the creation of polygraph idea and the theory. After a brief explanation of the title, the article will explain about the concise history of the polygraph. (16) In a study of patients with advanced heart failure who underwent pulmonary artery catheterization, Drazner et al compared impedance cardiography with invasive hemodynamic measurements.A Brief Introduction to Polygraph: This article will describe the etymology, word formation and definition of the polygraph to the readers. (15) Impedance cardiography provides noninvasive, readily available, and continuous measurements of cardiac output and other hemodynamic parameters such as systemic vascular resistance.
(14) Wagner's company, which produces a range of high-technology devices, including cardiographs and patient monitors, expects computers to revolutionize the way medical device manufacturers support customer training efforts. emergency departments use the four cardiographs that the Audicor CE runs with. (12) They may be assisted by cardiographers, and work closely with other technical and nursing staff. (11) Specifically, factors related to patients such as ventricular function and valve function were examined to determine if advanced heart failure and/or valve regurgitation affected the accuracy of impedance cardiography. (10) The department has a team of dedicated cardiographers who provide an ECG and ambulatory monitoring service across the whole hospital site. (9) A significant number of health workers - including nurses, radiographers, cardiographers and labourers - tested positive when they were scanned last week for thyroid nodules. (8) After the leads for impedance cardiography were applied, we were unable to accurately collect and record bioimpedance data from 4 patients. (7) His ears didn't pick up anything but the digital tick of the cardiograph, not the plodding footsteps or melodic dry thumps of a cane. (6) A cardiograph would be able to record my heart movements accurately and then you'd have a concise visual aid. (5) The gradient profile of the hills provided in my cycling guide looks suspiciously like the cardiograph reading of a 36-year-old having a heart attack, but I am not deterred. (4) Inovise went to four outside firms for help creating its Audicor cardiograph expansion system. (3) My son is now a house husband and part-time senior cardiograph technician working between two hospitals looking after two children. (2) The hospital issued a press release saying Lee is recovering well and that a physical examination and cardiograph showed his condition was normal. (1) The silence was broken only by the constant beep of the cardiograph, the electrical noise humming out every few seconds to indicate a resting, biologically functional heart resting inside of her battered ribcage.
