The Mathematics Of A Heart Beat Could Save Lives
What we perceive as the beating of our heart is actually the co-ordinated action of more than a billion muscle cells. Most of the time, only the muscle cells from the larger heart chambers contract and relax. But when the heart needs to work harder it relies on back-up from the atrial muscle cells deep within the smaller chambers (atria) of the heart...

A Novel Method For Simultaneously Measuring Blood Pressure And Arterial Stiffness
Arterial stiffness due to is a major contributor to cardiovascular disease but is very difficult to measure. It also can influence blood pressure readings since these rely on the time taken for arteries to return to normal volume and flow after compression. A new method for measuring arterial stiffness has been reported in BioMed Central's open access journal BioMedical Engineering OnLine...
