this is the Technology Report.Researchers have developed an experimentaliPhone application, or app,they can improve the chances of survivalfor heart attack victims.The iPhone app is specially designedto identify patients suffering from a heart attackknown as STEMI, or ST-elevation myocardial infarction.In STEMI, blood flow to the heart is stoppedbecause of a blockage in a coronary artery.Unlike other kinds of heart attacks,STEMIs show up very clearly on an electrocardiogram, or ECG.Doctors use such teststo measures a electrical activity in the heart.The experimental iPhone app,should be a great help to healthcare techniciansreacting to a possible medical emergency.They can perform an ECG,and then take a picture of the tests resultswith the camera on the telephone.They can then send that information aheadto hospital emergency-room doctors.The iPhone App is the work of David Burtand his students at the University of Virginia in Charlottesville.He says the app can help save livesby preparing doctors for the arrival of the STEMI patient."So a decision made as early as possiblein the STEMI treatment process allows the system to ramp upor mobilize so that when the patient shows up,they are pushed into the "cath" lab,everything happens and their artery gets opened ."David Burt and his team tested the app 1,500 timesover three American cellular phone networks in an populated area."If your iPhone at the time that you hit 'send' shows two or more bars,the app is successful in sending an image94-plus percent of the time in less than 10 seconds."The developers are now testing the iPhone app in rural areas,where cell phone reception is more problematic than in cities.In a separate story, a farmer in China who lost his handsin a fishing accident has turned his tragedy into a family business.His company now sells bionic arms to other amputees.Sun Jifa of Jilin province lost his hands nearly ten years ago.His own bionic arms was the first one he built.He says it transfers the powerfrom the natural movement of his elbows into the fingerallowing it to grab and hold.He turns his work into a home based business.Sun Jifa says he has sold about 1000 steel limbsat a cost of $490 each.He says they are less costlyand just as effective as hiher quality prosthesis.And that's the VOA Special English Technology Report.
