Sick Sinus Syndrome (SSS), or sinus node dysfunction (SND) ⚡This ECG visual highlights SSS-related rhythms: Sinus Bradycardia/Tachycardia, Sinus Pauses/Arrest, Exit Blocks, AFib, MAT, Junctional Escape, and more (e.g., AVNRT, AVRT if accessory pathways exist, ectopic atrial rhythms). Tachy-Brady Syndrome is common, with tachyarrhythmias predominating in most patients. Manage with pacemakers for bradyarrhythmias & rate control for tachycardias. #Cardiology #Electrophysiology #SickSinusSyndrome #E

#JACCCEP editors' insights: View a case report of transient severe sinus node (SN) dysfunction after radiofrequency (RF) application in the anterior-septal portion of the left atrium. In the case, tachycardia slowed and terminated with septal lesions, however, sinus pauses ensued. Coronary angiography revealed slow flow and stenosis in a SN artery that arose from the circumflex artery. The authors discuss the differential diagnosis and clinical management of sinus pauses following RF ablation. h
