A NEW MEDICAL TECHNOLOGY

A British ambulance racing to the hospital hit a large rut, throwing patient Ray Lee in the air. When Lee came down, the jolt reset his racing heartbeat from a potentially fatal 190 beats a minute to 60. “The paramedic looked at me in disbelief,’’ said Lee, 65. Lee said that he used to complain about local roads, “but now I never want them to fill in another pothole.”
