Pacemaker syndrome is a complication of mechanical pacemakers where the heart beats out of sync, causing decreased cardiac output. Symptoms include shortness of breath and fainting. Treatment options include adjusting the pacemaker’s programming or adding a second lead to pace the atria. A cardiologist is needed for accurate diagnosis. Patients should be alert for changes in heart rate and seek medical attention promptly if they develop warning signs.
Pacemaker syndrome is a possible complication of the use of a mechanical pacemaker in which a patient’s heart beats out of sync, leading to decreased cardiac output. It is an example of an iatrogenic medical condition, a problem caused by medical intervention. When a patient is diagnosed with pacemaker syndrome, several treatment options are available, including adjusting the pacemaker’s programming.
When a mechanical pacemaker is implanted, it monitors the heart rhythm with a series of electrical signals. These devices are used when a patient’s heartbeat is irregular and the patient is at risk for health problems. In some patients, the pacemaker causes the ventricles to contract before the atria, effectively causing the heart to beat in reverse and forcing blood against the closed valves between the chambers of the heart. This makes the heart work harder and leads to pacemaker syndrome.
Patients with pacemaker syndrome may experience shortness of breath, fainting, and a pounding sensation in the chest. Symptoms vary and are sometimes confused with other medical problems. This condition tends to resist recognition by a physician, unless a patient has a history that suggests she may be at risk for pacemaker syndrome. People with a slow heart rate, for example, are more likely to develop this condition when a pacemaker is installed.
One option to manage pacemaker syndrome is to adjust the pacing to see if the heart can be brought back into sync. If this fails and a patient has only ventricular pacing, a second lead can be connected to pace the atria as well. This should fix the problem. Some patients even experience benefits when they modify their diet to reduce blood pressure and promote cardiovascular health.
A cardiologist is usually needed to accurately identify and diagnose pacemaker syndrome. This specialist doctor may order an EKG to learn more about how the heart beats, as well as listen to the heart and order some heart function tests, looking for problems such as decreased cardiac output that suggest a patient may have heart syndrome. pacemaker. If detected early, this condition should not cause complications for the patient.
Improper pacing is one of the potential risks of permanent cardiac pacing. Patients should be alert for changes in heart rate, as well as for symptoms of cardiovascular problems, so that they can seek medical attention promptly if they develop warning signs of complications or new medical problems while using a pacemaker.
