It can take 5-10 years or even longer from the onset of symptoms to severe symptoms. The onset of SSS is insidious, and the course of development is mostly slow. Journal of Cardiology and Therapy 2020 7(1): 913-921 Available from: URL: http: //Clinical manifestations and aetiology New Strategies for the Treatment of Sick Sinus Syndrome. Sick sinus syndrome Pathogenesis Traditional therapy Gene therapy This article aims to summarize the aetiology and pathogenesis of SSS, discuss the advantages and disadvantages of traditional treatment methods, and focus on the biological pacing strategies based on gene and cell therapy. Hence, there is an urgent need to develop targeted therapies in order to treat SSS. Traditional therapies for SSS include drug therapy and pacemaker implantation, which have only partially succeeded clinically and cannot cure SSS. The aetiology of the syndrome is complex, and the pathogenesis is unknown. Sick sinus syndrome (SSS) is an organic disorder of the sinoatrial node and its adjacent tissues, which causes problems in sinus node pacing function and sinus node conduction, thus leading to arrhythmias and multiple symptoms.
