Atrial Fibrillation (AFib) vs. Normal Rhythm: A Visual Guide 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 #Cardiologist #A
