Low Pulse Rate. Your heart will typically beat between 60-100 times each minute when you are at rest. Bradycardia refers to a heart rate that is below 60 beats per minute. In most cases bradycardia does not cause complications or symptoms, but this can be a serious condition because a low pulse rate means the heart is not pumping an adequate supply of oxygen rich blood to the rest of the body.
According to the American Heart Association, a normal resting heart rate is 60 to 80 beats a minute, or about one beat per second. Well-trained athletes sometimes have resting heart rates as low as 40 beats per minute, but for those who exercise only casually or not at all, a heart rate this low is not normal. It is best to take your heart rate before you get out of bed after a night of sound sleep.
