An article of the NIH, National Institutes of Health, states that a dramatic leap in mHealth will take place when we have small, inexpensive wireless devices with sensors that monitor our physiology. This means our heart rate, blood pressure, blood sodium and glucose levels, breathing patterns, brain waves and so on. These can then be transmitted to the physician, who can in his turn take actions that may spare you a trip to the hospital or even save your life.
In a clinical trial, a wireless adhesive patch was tested next to the traditional technology (the Holter) to measure heart activity. With the traditional technology, the Holter must be worn for 24 hours; it records the full 24 hours. Getting a good reading is particularly challenging when the arrhythmias occur episodically. The adhesive patch can be carried around for a longer time, like a week. The patch had 15% less use-able readings in the first 24 hours but people were asked to wear it until they could tolerate it. The subjects wore the adhesive patch for 11 days on average. Because people wore the patch longer, there were significantly more (96) use-able readings than with the Holter (61). Nice data that demonstrates cardiac event monitoring works.
The cardiac event recorders, developed by Vitaphone, send the registered events within seconds to the physician or the events are firstly analyzed in the telemonitoring Service Centre and then sent through. Many event recorders are in use by Dutch hospitals. Have a look at the users list >
Cardiac event recording is available and can function as replacement for the Holter monitoring!
