Abstract

A system in accordance with present embodiments includes an electrocardiograph, a plurality of sensors communicatively coupled with the electrocardiograph, wherein each of the plurality of sensors comprises an electrode capable of detecting electrical impulses generated by a patient'"'"'s body and transmitting signals indicative of detected electrical impulses to the electrocardiograph. In one embodiment, the system also includes a motion detection feature communicatively coupled with the electrocardiograph, wherein the motion detection feature is capable of detecting movement of the patient'"'"'s body and providing signals indicative of detected movement to the electrocardiograph, and wherein the electrocardiograph is capable of detecting a particular type of patient motion and/or patient position based on the signals indicative of the detected motion, capable of providing output based on the signals indicative of the detected electrical impulses, and capable of providing output based on the signals indicative of the detected movement.
