However, the link is often hard to prove. An ECG may show abnormal heart rhythms related to this syndrome. Holter or longer term rhythm monitors are effective tools for diagnosing sick sinus syndrome.
They may pick up very slow heart rates and long pauses, along with episodes of atrial tachycardias. Types of monitors include event monitors, loop recorders, and mobile telemetry. An intracardiac electrophysiology study EPS is a very specific test for this disorder. However, it is not often needed and may not confirm the diagnosis. In some cases, a person's heart rate is observed when walking or exercising to see if it increases enough.
You may not need treatment if you do not have any symptoms. Your health care provider will review the medicines you take to make sure they are not making your condition worse. Do not stop taking any of your medicines unless your provider tells you to do so. You may need a permanent implanted pacemaker if your symptoms are related to bradycardia slow heart rate. A fast heart rate tachycardia may be treated with medicine.
Sometimes, a procedure called radiofrequency ablation is used to cure tachycardia. 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.
Keeping your heart healthy by eating a well-balanced diet and exercising can prevent many types of heart disease. Bradycardia-tachycardia syndrome; Sinus node dysfunction; Slow heart rate - sick sinus; Tachy-brady syndrome; Sinus pause - sick sinus; Sinus arrest - sick sinus. Patients who have sick sinus syndrome with only sinus bradycardia have a better prognosis. One study 3 indicated that mortality rates in these patients may not be different from mortality rates in the normal population.
Researchers conducting one literature review 22 concluded that patients with this syndrome who require atrial or dual-chamber pacing have a mortality rate of 3. There is a high prevalence of cardiovascular disease in patients with sick sinus syndrome who die within the first few years of pacemaker implantation.
Recent improvements in rate-responsive pacemaker engineering have led to improvements in maximum heart rate, exercise tolerance, functional status, suppression of dysrhythmias, and sense of well-being in patients.

Abstract An year-old woman was scheduled for a second transurethral resection of a bladder tumor. Keywords: Artificial cardaic pacing, Atrial fibrillation, Sick sinus syndrome. Case Report An year-old woman height: cm, weight: 56 kg was admitted to the outpatient center to receive a second transurethral resection of a bladder tumor TURBT.
Open in a separate window. Electrocardiogram monitored in the operation room. B Sinus pause after atrial fibrillation rhythm was observed before pacemaker insertion. D Pacing rhythms were observed during sinus pauses after pacemaker insertion. Electrocardiogram taken after insertion of a permanent pacemaker. Discussion Atrial fibrillation is the most common type of arrhythmia in the elderly [ 5 ] and it is times more common than atrial flutter [ 6 ]. References 1.
