First-degree heart block may not cause any symptoms or require treatment. If you have second-degree heart block that doesn't require a pacemaker, talk with your doctor about keeping your heart healthy. Your doctor will tell you whether you need ongoing care for your condition. People who have third-degree heart block and some people who have second-degree heart block need pacemakers. This device uses electrical pulses to prompt the heart to beat at a normal rate. If you have a pacemaker, you should take special care to avoid things that may interfere with it. Avoid close or prolonged contact with electrical devices and devices that have strong magnetic fields. These objects can keep your pacemaker from working properly. Let all of your doctors, dentists, and medical technicians know that you have a pacemaker. You also should notify airport screeners. Your doctor can give you a card that states what kind of pacemaker you have. Carry this card in your wallet. You may want to consider wearing a medical ID bracelet or necklace that states that you have a pacemaker. Certain medical procedures can disrupt pacemakers. Examples include magnetic resonance imaging (MRI), electrocauterization during surgery, and shockwave lithotripsy to get rid of kidney stones. Your doctor may need to check your pacemaker several times a year to make sure it is working well. Some pacemakers must be checked in the doctor's office, but others can be checked over the phone. Ask your doctor about what types of physical activity are safe for you. A pacemaker usually would not limit you from doing sports and physical activity. But you may need to avoid full-contact sports, such as football, that can damage the pacemaker.
