If you have Bradycardia, your heart beats fewer than 60 times a minute. Bradycardia can be a serious problem if the heart rate is very slow, and the heart can’t pump enough oxygen-rich blood to the body. If this happens, you may feel dizzy, very tired, or weak, and short of breath. There are other circumstances when the heart rate may be too slow as a reaction to varied possibilities, but this TKM procedure has shown to be very effective in each case.
