FORT LAUDERDALE, Fla. -- Orioles pitcher David Wells underwent tests yesterday to determine the cause of a rapid heart rate that started increasing Sunday night, and one of the first tests revealed no abnormalities.Wells, 32, checked into Holy Cross Hospital here and was expected to remain under care overnight, as the tests continued and his rapid heart rate was treated. One of the first tests, an EKG, revealed no abnormalities, according to Orioles team doctor William Goldiner.A rapid heart rate, Goldiner said, "may or may not be serious.

A study of premature babies has found that a declining heart rate is responsible for at least some cases of sudden infant death syndrome, challenging the widespread belief that SIDS occurs when an infant unaccountably stops breathing.Dr. Robert G. Meny, a pediatrician at the University of Maryland Medical Center, said the finding should push research in a new direction -- prompting doctors to explore why the heart rate slows and what might be done to prevent it."With these recorded deaths we find there was a heart rate problem before the babies stopped breathing," said Dr. Meany, director of clinical services at the university's SIDS Institute.

In 1960 Gordon Spitzmesser, an Indiana tool-and-die maker with an apparently restless mind, invented the gas-powered pogo stick. The "Pop Along" worked fine. Too fine. The government felt the super toy was a safety hazard and quickly pulled it off the market (whereupon Spitzmesser refocused his attention on trying, unsuccessfully, to create a car that could run on water). "There's just a fascination with bouncing that humans have," observes Jeff Bergerson, a 29-year-old Washington state personal trainer and extreme skier who has fallen in love with a newer and potentially safer version of the high-performance pogo stick.

The new year brings a lot of resolutions to exercise. And sometimes the cold weather also means more snow shoveling. All that exertion can be harmful to people with abnormal hearts by leading to sudden cardiac arrest. Dr. Gordon Tomaselli, director of cardiology at Johns Hopkins Hospital, talks about the difference between sudden cardiac arrest and a heart attack and what those at risk can do. Question: What is sudden cardiac arrest? Answer: Sudden cardiac arrest refers to collapse and loss of consciousness due to a dramatic fall in blood pressure.

The fascination with heart-rate monitors reached new heights after the Outdoor Life Network showed the pulse of some riders in the Tour de France in July. It's like having a cockpit view of an auto racer's instrument panel. Perennial champ Lance Armstrong didn't volunteer his real-time data; he didn't want competitors to know when he was truly sweating. But his heart-rate numbers, which provide a rare glimpse into his freakishly efficient body, are legendary and telling. When Armstrong is relaxing off the bike, his resting heart rate, or pulse, has been measured at just 32 beats per minute, less than half that of the average man. When he's sprinting up a steep mountain, it might spike to around 200 beats per minute.

A run, swim or bike ride that merely feels strenuous may not always boost your heart rate into the "aerobic zone." Aerobic exercise lowers blood pressure, improves cholesterol profiles, burns body fat and reduces the risk of heart attack. It's worthwhile, in other words, to find out just how hard your heart is really working.No set of sensations -- breathing hard or breaking into a sweat -- signifies a suitably beneficial workout for everybody in every setting. But with practice you can learn to connect your perceived exertion to your heart rate.
