As a medical professional with expertise in cardiology, I can provide you with information on the symptoms that may indicate a failing pacemaker. A pacemaker is a small device that helps regulate the heartbeat by sending electrical impulses to the heart muscle. When a pacemaker is not functioning properly, it can lead to a variety of symptoms. Symptoms of a failing pacemaker include: 1. Fainting (Syncope): This can occur if the pacemaker is not delivering the necessary electrical impulses to the heart. 2. Dizziness or Lightheadedness: Feeling unsteady or lightheaded can be a sign that the heart rate is not being properly regulated. 3. Fatigue: A lack of energy may be due to an irregular heartbeat that is not being corrected by the pacemaker. 4. Shortness of Breath: This can be a result of the heart not pumping blood efficiently. 5. **Rapid or Irregular Heartbeat (Palpitations)**: The heart may not be beating at the correct rate or rhythm. 6. Chest Pain: This could be a sign of the heart not receiving enough oxygen due to a pacemaker malfunction. 7. Swelling in the Legs or Feet: If the heart is not pumping effectively, it can lead to fluid retention. If you experience any of these symptoms, it is important to seek medical attention immediately, as they could be a sign that your pacemaker needs to be checked or adjusted. read more >>
