What if you were having a heart attack, but no one believed you A new study of 515 female heart-attack survivors (aged 29 to 97) reveals that this happens all too often.
In the study, 95% said they knew something was seriously wrong a month or more before their heart attack, but none of their doctors had even told them that they had heart disease. And when their heart attack happened, fewer than 30% had chest pain or discomfort, the classic warning signs that most emergency room physicians and nurses look for.
One study volunteer in her mid-30s had a heart attack while driving her children to school. "She had repeatedly sought help for early warning symptoms," says study author Jean McSweeney of the University of Arkansas for Medical Sciences. Despite abnormal cardiac stress test results, she got no treatment. Two weeks later, she nearly died.

A. no one believes women’s study
B. few people believe women’s warning signs

Scientists Develop Ways of Detecting Heart Attack
German researchers have (1) a new generation of defibrillators and early warning software aimed at offering heart patients greater protection (2) sudden death from cardiac arrest.
In Germany alone around 100,000 people die annually as a result of cardiac arrest and many of these cases (3) by disruption to the heart’s rhythm. Those most at risk are Patients who have (4) suffered a heart attack and for years the use of defibrillators has proved useful in diagnosing (5) disruptions to heart rhythms and correcting them automatically by intervening within seconds. These devices (6) a range of functions such as that of pacemaker.
Heart specialists at Freiburg’s University Clinic have now achieved a breakthrough with all implanted defibrillator (7) of generating a six-channel electrocardiogram(ECG) within the body. This integrated system allows ea
