EDITORS COMMENTS
This print showcases the Lewis-McKenzie polygraph, a groundbreaking medical device manufactured in 1900 by the esteemed Cambridge and Paul Instrument Co. The polygraph revolutionized the field of cardiovascular diagnosis by enabling simultaneous graphical recording of venous and arterial pulses. With its red background adding an air of vintage allure, this antique instrument stands as a testament to the ingenuity of early 20th-century medicine. The Lewis-McKenzie polygraph consists of two tambours, one placed on the jugular vein in the neck and another on the brachial artery in the arm. These tambours meticulously register each pulse while mounted pens trace their patterns onto a continuous roll of paper. This innovative technology allowed physicians to diagnose arrhythmias with unprecedented accuracy. As we delve into its historical significance, it becomes evident that this device played a pivotal role in advancing our understanding of cardiovascular health. Its presence evokes thoughts about how far medical equipment has come since then, yet also serves as a reminder that even today's cutting-edge diagnostic tools owe their existence to these early inventions. With its rich history and intricate design, this Lewis-McKenzie polygraph print is not only an exquisite piece for collectors but also an emblematic representation of humanity's relentless pursuit to unravel the mysteries within our bodies.
