Ambulatory cardiopulmonary data capture

A recently developed system, the LifeShirt/sup TM/ (VivoMetrics, Inc., Ventura, CA, USA), provides, for the first time, reliable ambulatory monitoring of a wide variety of cardiovascular, respiratory, motor-behavior, and experiential responses. The system consists of a comfortable garment with embedded inductive plethysmography sensors, a 3-lead, single channel electrocardiogram (ECG), a two-axis accelerometer and a handheld computer for the capture of time-stamped, experience data input via a touch screen. Parameters are extracted offline using sophisticated analysis and display software. The device is currently used in academic research and clinical studies, but is not limited to this application.
