　　Throughout the United States, and especially in big cities and rural areas, tens of thousands of people with hearts that should be good 　　　　　 to keep them alive die each year for lack of adequate first aid. In New York City, for example, a new study has shown that only one person in 100 outside of hospitals 　--　　 after the heart suddenly stops pumping . In contrast, in Seattle, the survival 　　　--　　 after such heart attacks is one in five.

It continues with the prompt arrival-within eight 　　　__　　 ten minutes of a rescuer equipped with a special instrument that can shock the heart back to a normal rhythm. And it ends with the administration of advanced emergency care by nurses to maintain the hearts ability to survive until the doctors at the hospitals can take . When one or more links in this chain fail or function too slowly, the 　　__　　　 of a victim surviving heart attack falls rapidly. Because of widespread weaknesses in the chain of 　　　__　　, experts in emergency heart care estimate that 20,000 to 80,000 people 　　__　　　 needlessly of heart attack each year, a number comparable to the 55,000 killed annually in automobile 　　　　　.
