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.
Causes of Shortness of Breath. Shortness of breath can be caused by many things, such as: 1  Lung damage from cancer or cancer treatments. 2  Blood clots in your lungs (pulmonary embolism). 3  Fluid around your heart or lungs. 4  Lung infection (pneumonia). 5  Asthma or emphysema. 6  Heart damage (congestive heart failure).
