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.
A low pulse rate may be caused by a number of health conditions. Sometimes, a form of heart disease is the reason for slower blood flow throughout the body. Cardiac abnormalities are common, but other conditions that do not involve the heart, such as a metabolic imbalance or certain lung diseases, can create the symptom.
