7/25/2023 0 Comments Sick sinus syndrome and pacemakerSSS occurring spontaneously or as a result of necessary drug therapy, with heart rate less than 40 bpm when a clear association between significant symptoms consistent with bradycardia and the actual presence of bradycardia has not been documented. Symptoms Most people with sick sinus syndrome have few or no symptoms. Sick sinus syndrome may also be called sinus node dysfunction or sinus node disease. In some patients, bradycardia is iatrogenic and will occur as a consequence of essential long-term drug therapy of a type and dosage for which there are no acceptable alternatives. Many people with sick sinus syndrome eventually need an implanted device called a pacemaker to keep the heart in a regular rhythm. SSS with documented symptomatic bradycardia, including frequent sinus pauses that produce symptoms. 5 Furthermore, there is no definitive way to distinguish patients with atrial fibrillation associated with sick sinus syndrome from patients with atrial fibrillation and normal sinus function this distinction is clinically important because treating atrial fibrillation with cardioversion or medications can have catastrophic consequences if the sinus node is inadequate. 2 If the patient is asymptomatic when ECG or ambulatory monitoring is performed, the dysrhythmias of the syndrome are often not present. Sick sinus syndrome is a type of heart rhythm disorder that affects your sinus node, your hearts natural pacemaker. 5 Symptoms of sick sinus syndrome may be variable, intermittent, and difficult to associate with ECG changes. Anticoagulation therapy has not been directly compared with antiplatelet therapy in this population, although clearly, in patients with paroxysmal AF, warfarin. 9 Some symptoms of patients with sick sinus syndrome (e.g., fatigue, irritability, memory loss, lightheadedness, palpitations, cognitive defects) are present in several other disorders that occur in elderly patients and may be misdiagnosed as those of senile dementia. Patients treated with permanent pacemakers for sinus node dysfunction are elderly and have a substantial mortality rate, with more than half the classifiable. The condition often goes undetected in the early stages because only sinus bradycardia may be present at its origin. This can lead to an abnormally slow heartbeat (bradycardia), an abnormally fast heartbeat. In patients with bradycardia who have indi-cations for pacemaker implantation, shared decision-making and patient-centered care are endorsed and emphasized in this guideline. The diagnosis of sick sinus syndrome may be difficult because of the slow and erratic course of the syndrome. In sick sinus syndrome, the SA node doesnt work as it should. veillance and pacemaker implantation are made in this guideline.
