Cardiovascular disease is kills almost 20 million people each year, with around 22 million people at risk of sudden heart failure at any one time around the world. Lives can often be saved if acute care and cardiac surgery are carried out within the so-called golden hour. And, survival rates are on the increase as treatments improve. However, this means more and more patients whose cardiac health has to be monitored so that follow-up treatment can be given if problems arise. Available methods of heart monitoring usually restrict the mobility of patients to a hospital or a single room.
Thulasi Bai and S.K. Srivatsa of the Sathyabama University in Tamil Nadu, have developed a wearable cardiac telemedicine system that allows post-cardiac patients renewed mobility.
Bai's prototype Bluetooth heart monitor records periodically an electrocardiogram (ECG) and transmits the information via radio frequency signals to the patient's mobile phone. The modified phone has an added analyser circuit that checks the ECG signal for signs of imminent cardiac failure. If errant signals are detect, such as any arrhythmia, the mobile phone alerts the patient and transmits a sample of the ECG signal to the nearest medical care centre, via the SMS text service, together with patient details.
The device could give patients who have already had one heart attack a much greater chance of receiving life-saving treatment within the golden hour period.
"Our Wearable Cardiac Telemedicine System can help the mobility of patients, so they can regain their independence and return to an active social life or work schedule," explains Bai, "thereby improving their psychological well-being and quality of life."
The researchers are now working on how to enable global-positioning system, GPS, in the modified mobile phone, so that the medical centre can more quickly pinpoint the patient. They also hope to improve the level of detail that can be sent from the mobile phone to the emergency room using the Multimedia Messaging Services (MMS) as opposed to the SMS text messaging system.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
