infant heart beat normal rate
1. Myth: A normal heart rate is 60-100 beats per minute. That's the old standard. Many doctors think it should be lower. About 50-70 beats per minute is ideal, says Suzanne Steinbaum, MD, director of women's heart health at Lenox Hill Hospital. Recent studies suggest a heart rate higher than 76 beats per minute when you're resting may be linked to a higher risk of heart attack.
