Sinus Rhythm & Core Variations · Normal Sinus Rhythm (NSR): The physiological standard. Regular rhythm (60-100 bpm), with a normal P wave preceding each narrow QRS complex. · Sinus Tachycardia: >100 bpm. A normal physiological response to demand (e.g., exercise) or a sign of pathology (e.g., fever, anemia). · Sinus Bradycardia:

Atrial Fibrillation (AFib) vs. Normal Rhythm: A Visual Guide ✨ @cardiovisual Normal Sinus Rhythm: ✅Synchronized electrical impulse. ✅Clear P-wave before each QRS complex. ✅Efficient pumping = optimal blood flow. Atrial Fibrillation: ❌Chaotic electrical activity in the atria. ❌Missing P-waves. Irregular baseline ("fibrillary waves"). ❌Irregularly irregular ventricular response. ❌Blood pools, increasing stroke risk by 5x. Recognize the rhythm. Prevent the stroke. #Electrophysiology #MedicalSchool
