You may need to avoid some types of medicines. Keeping your heart healthy by eating a well-balanced diet and exercising can prevent many types of heart disease. The long-term outlook is excellent for people who have a permanent pacemaker implanted. This means it gets worse over time in most cases. ![]() In some cases, medicines used to control periods of fast heart rate are combined with use of a pacemaker, which guards against periods of slow heart rate. Sometimes, a procedure called radiofrequency ablation is used to cure tachycardia. You may need a permanent implanted pacemaker if your symptoms are related to bradycardia (slow heart rate).Ī fast heart rate (tachycardia) may be treated with medicine. Do not stop taking any of your medicines unless your provider tells you to do so. Your health care provider will review the medicines you take to make sure they are not making your condition worse. You may not need treatment if you do not have any symptoms. In some cases, a person's heart rate is observed when walking or exercising to see if it increases enough. However, it is not often needed and may not confirm the diagnosis. Types of monitors include event monitors, loop recorders, and mobile telemetry.Īn intracardiac electrophysiology study (EPS) is a very specific test for this disorder. They may pick up very slow heart rates and long pauses, along with episodes of atrial tachycardias. Holter or longer term rhythm monitors are effective tools for diagnosing sick sinus syndrome. However, the link is often hard to prove.Īn ECG may show abnormal heart rhythms related to this syndrome. Sick sinus syndrome is diagnosed when the symptoms occur only during episodes of arrhythmia. Sick sinus syndrome may cause symptoms of heart failure to start or get worse. The heart rate may be very slow at any time. Shortness of breath, possibly only with physical activity like walking.Sensation of feeling the heart beat ( palpitations).Confusion or other changes in mental status.Symptoms that do occur may mimic those of other disorders. These include digitalis, calcium channel blockers, beta-blockers, and antiarrhythmics. Some medicines can make abnormal heart rhythms worse, especially when doses are high. When there are periods of both slow and fast heart rates (rhythms) the condition often will be called tachy-brady syndrome. A period of fast heart rates is often followed by very slow heart rates. ![]() These include atrial fibrillation, atrial flutter, atrial tachycardia. Tachycardias (rapid heart rhythms) that start in the upper chambers of the heart may be part of the syndrome. Sinus bradycardia occurs more often than the other types of the condition. It is the most common reason people need to have an artificial pacemaker implanted. Sick sinus syndrome is uncommon, but not rare. However, these diseases may have nothing to do with the syndrome. In children, heart surgery on the upper chambers is a common cause of sick sinus syndrome.Ĭoronary heart disease, high blood pressure, and aortic and mitral valve diseases may occur with sick sinus syndrome. It is often due to scar-like damage to electrical pathways in the heart muscle tissue. Sick sinus syndrome most often occurs in people older than age 50.
