    Area of Science:

    • Cardiology
    • Electrophysiology

    Background:

    • Sinus node dysfunction, or sick sinus syndrome, is increasingly recognized as a significant cause of morbidity, especially in the elderly.
    • It is not a single disease but encompasses various pathological conditions and mechanisms leading to clinical and electrocardiographic manifestations.

    Purpose of the Study:

    • To review the diagnostic challenges and therapeutic approaches for sick sinus syndrome.
    • To highlight the current limitations in diagnostic testing and the established role of ECG monitoring.

    Main Methods:

    • Review of existing literature on sinus node dysfunction.
    • Analysis of diagnostic tests and their clinical utility.
    • Evaluation of current treatment strategies, including pacemaker therapy and antiarrhythmic drugs.

    Main Results:

    • Various pathological conditions can lead to sick sinus syndrome.
    • Current diagnostic tests have limited clinical value.
    • Electrocardiogram (ECG) monitoring remains the primary diagnostic tool.

    Conclusions:

    • Sick sinus syndrome is a complex condition with diverse underlying causes.
    • Effective diagnosis relies heavily on continuous ECG monitoring.
    • Treatment focuses on symptomatic relief through pacemakers and pharmacotherapy for associated arrhythmias.
