You might need a pacemaker if your heart beats too slow
If your resting heart rate is lower than 60 beats per minute, that’s known as bradycardia. In serious cases, your heart may not be able to pump enough blood to the rest of your body. Certain medications and conditions, like thyroid issues or sleep apnea, can cause it. If that’s the case, your doctor will change your prescriptions or treat the cause. If not, a pacemaker (a small battery-operated device) can be put under your collarbone to keep your heartbeat at a normal rate.
