What are the 3 primary problems that can occur with a pacemaker?

Pacemaker failure has three causes: (1) failure of capture, (2) lead failure, and (3) generator failure. Failure of capture owing to a defect at the level of the myocardium (i.e., the generator continues to fire but no myocardial depolarization takes place) remains the most difficult problem to treat.

What are the most common problems with a pacemaker?

Pacemaker Malfunction It usually involves failure of the pulse generator or the lead(s). It presents as failure to pace, failure to capture, inappropriate sensing (over- or under-sensing), or dysrhythmia. Inappropriate sensing and failure to capture are the two most common malfunctions.

What happens to your heart when you have a pacemaker?

When the heart’s natural pacemaker is defective, the heartbeat may be too fast, too slow or irregular. Rhythm problems also can occur because of a blockage of your heart’s electrical pathways.

How does the pulse generator in a pacemaker work?

The pacemaker’s pulse generator sends electrical impulses to the heart to help it pump properly. An electrode is placed next to the heart wall and small electrical charges travel through the wire to the heart.

Is there a delay in heart valve disease?

However, there is nearly always a long delay between the beginning of heart valve disease and the development of clinical heart problems. Regular check-ups are key to the proper treatment of any heart valve problems.

When to worry about heart palpitations in men?

Palpitations can be a sign of a heart problem. This is more likely in men or people with heart disease. If your palpitations are frequent, worsening, or lasting more than five minutes, speak with your doctor about your symptoms. Some groups of people are at higher risk than others.

What is the life expectancy of a person with a pacemaker?

The average life expectancy og pacemaker is about 10 years. Pacemaker can last for 15 years or longer depending on frequency of use and few other factors that may cause unnecessary discharge of electric power.

What are signs of failing pacemaker?

Clinical symptoms of pacemaker malfunction are variable and include syncope, dizziness, palpitations, and slow or fast heart rate. Extracardiac stimulation or hiccough may be present.

What are the risks of getting a pacemaker?

The most common pacemaker risks are infection at the pacemaker site, bleeding or bruising, bad reactions to anesthesia, and implantation of a faulty pacemaker. These risks are still quite low, especially in a reputable medical facility.

Why is my pacemaker not working?

The problem is, with rates below fifty, the atrial pacemaker is not working. Usually this is because there is dead tissue (an infarct), however the atrial pacemaker may be destroyed. Your rate indicates you are on the back-up pacemaker site.
