You'll know if you're having a heart attack?

Monday, September 8, 2008

Not necessarily. About half of all people who have had heart attacks never felt a symptom - or didn't recognize it. The most commin signs are:

1. Chest discomfort (pressure, fullness or squeezing)
2. Discomfort in upper body (arm, back, neck, jaw or shoulder)
3. Shortness of breath
4. Cold sweat
5. Nausea
6. Sudden extreme fatigue (without lack of sleep)

Symptoms can be unpredictable. For example, talk show Larry King felt intense pain in his right arm, not the usual side for heat pain. Why? The heart's nerve don't fell pain directly. But when something goes wrong, its nerves may become electrically unstable. When they cross the spinal column, they may short-circuit other nerves - so your arm arches, or your chest, or even your jaw. But if the nere fibers don't cross, you may not have any discomfort at all.
