The ability to monitor body position and physical activity during ambulatory recordings of ECGs can aid in clinical diagnosis in assessing both physiologic changes and motion artifacts. We have developed a device which, through the use of appropriately placed micro-fabricated accelerometers, can simultaneously record body position information along with two channels of ECG. This study validates the functioning of such a device by recording from five healthy subjects and twenty patients who were asked to wear the device for one hour. A predetermined protocol of defined periods of standing, sitting, lying supine, and walking was followed. The recordings show that the assessment of body position and motion are highly reliable (90% accuracy) therefore allowing correlation with ECG signals.
