(HealthDay News) -- If you've had a pacemaker implanted, the American Heart Association says you should take certain precautions to stay healthy and make sure your pacemaker is working properly.
Be sure your doctor has given you guidelines on recognizing a healthy heart rate, and when an unusual heart rate signals trouble. You should check your pulse regularly, and keep records to discuss with your doctor at your next office visit.
Take your heart medications exactly as prescribed by your doctor -- they work with your pacemaker, so it's important to keep taking them.
You'll also need to watch your diet and physical activity, and keep the area near the pacemaker protected from pressure or injury. If you notice a significant change in heart rate, swelling, weight gain, trouble breathing or dizziness, contact your doctor immediately.
