A pacemaker is a small device that is placed in the chest to help control abnormal heart rhythms. The pacemaker uses electrical pulses to signal the heart to beat at a normal rate. The pacemaker can help relieve the symptoms of arrhythmia, including fatigue and fainting and help a person resume a more active lifestyle.
Pacemakers work by speeding up a slow heart rhythm or helping to control an abnormal or fast heart rhythm. They monitor and record the heart’s electrical activity and rhythm.
Pacemakers can be temporary to treat a slow heart rate after a heart attack, or permanent to help support a slow heart rate, or bradycardia.
