NOVEL STRESS TEST using Phono- and Pressocardiography (pulse-pressure recording over the left ventricular beat) with short isometric exercise (Presso Test). There are a lot of published data and an experience wuith more than 8.000 patients. Based on exact criteria of diastolic abnormalities, one can screen patients with subclinical myocardial diseases, esp. Coronary artery disease in daily practice (www.presso-test.com). We should explore further this useful sensitive diagnostic tool and develop more devices from the existing phono devices -even handheld and ipad!- by filtering or including a starin gage transducer.

an aditional connection to the 2 or more electrodes that the article describes must be set in order to ground the patient to earth in ECG devices. Even if it is a so called "wireless" one.

Just to add my $0.02 worth to my colleague Sanjeev's article, the new PSoC3 devices have a lot going for them in physiological monitoring applications - highly configurable analog stuff including a best-in-class ADC, easily programmed custom digital logic, great signal processing capabilities and solid easy-to-use support for Apple devices. Really simplifies the design of these things!
I am a PSoC user. I like the product because it was given to me free at ESC Boston in 08'. It's pretty cool to do small projects. I just have a question about your figure 5. Two signals go into your ADC, but nothing seems to be coming out. I dun't understand that. What are you trying to convey?
A very informative article explaining in the layman's terms the various methods of measuring pulse rate. Would be interested to know how PSoc configurable IC is more advantageous in implementing solutions for such applications as against the general purpose micro controllers.
