A pacemaker is a small, battery-powered device that sends electrical signals to the heart to keep the heartbeat steady. Thin wires, called leads, carry the signals from the pacemaker to the heart. A pacemaker can prevent or reduce dizziness, fainting, and shortness of breath caused by a slow or unsteady heartbeat. Your chest may be sore where the doctor made the cut (incision) and put in the pacemaker. You also may have a bruise and mild swelling. These symptoms usually get better in 1 to 2 weeks.
Aortic stenosis is a condition of the heart causing shortness of breath, dizziness, or chest pain. Atrial flutter is an abnormality of the heart's rhythm that causes rapid and sometimes irregular heartbeats. Pulmonary hypertension can cause shortness of breath, a fast heart rate, or lightheadedness.
