The PocketECG system from MEDICALgorithmics is a good example of where medical device design is headed. The PocketECG is essentially a Holter monitor combined with a physical activity tracker. What is significant is that, with data being collected on both heart rhythm and physical activity, it allows correlates to be established that can provide a more complete view of arrhythmia over time. That, in turn, can help doctors make better treatment decisions for their patients.

This is the kind of device that will allow the data it collects to be analyzed to reveal all kinds of relationships between physical activity/lifestyle and its effect on an individual patient’s physiology. We will be seeing similar types of devices that will target other disease states.

In a few years, the PocketECG will be viewed as a relatively primitive device. But right now, it is on the leading edge of where medical device design is headed. This represents a significant opportunity for the medical device companies that can recognize it as such.
