The American Heart Association states that approximately three million people across the globe have been fitted with pacemakers, most of which are to treat bradycardia, or a heart rate that's too slow. Once your implant is done, you should be able to continue with most of your regular activities, including exercise. However, consult with your cardiologist before beginning any exercise program or sport.
How a Pacemaker Works
Your sinus node regulates your heart beat by sending out electrical signals that stimulate your heart to beat. A pacemaker provides these electrical signals when the signals from your sinus node is no longer efficiently regulating your heart beat. Your pacemaker system will have a computer circuit and the necessary attachment wires plus a battery. Most modern pacemakers have features that allow heart rate to be adjusted to accommodate situations where your heart rate needs to speed up, such as during exercise.
Exercising with a Pacemaker
When you first get a pacemaker, begin your exercise program with short aerobic workouts of moderate intensity. You can increase the intensity and length of the program over time. You may also be able to play a range of sports, including tennis, golf, scuba diving and running. Consult with your cardiologist, because your pacemaker itself may not limit your exercising, but other medical conditions might necessitate restrictions.
Exercises to Avoid
Full-contact sports are not recommended for anyone with a pacemaker. Your pacemaker may malfunction if there is impact on your chest on or near your implant site. Some yoga positions, butterfly swim strokes and swinging a racket or golf club with both hands should also be avoided. The range of movement that these activities require may damage one of your pacemaker wires.
Considerations
Symptoms of a need for a pacemaker can include dizziness, fainting, weakness, fatigue and low blood pressure. Lack of energy, shortness of breath and an inability to exercise may also occur. A pacemaker can resolve these problems, allowing you to resume normal activities.
If you have a pacemaker, the AHA recommends adopting a "heart healthy" lifestyle, one that includes an appropriate diet, adequate exercise and taking whatever medications are prescribed to treat your heart condition.
