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

SA Node: 60–100 bpm AV Node: 40–60 bpm Ventricles: 20–40 bpm  Causes Severe sinus disease Advanced AV block Myocardial infarction Drug toxicity (e.g., beta-blockers, digoxin) Hyperkalemia Cardiac surgery complications. #Cardiology #ECG #Arrhythmia #MedEd #idioventricularrhythm | Abdallah Othman | Facebook
