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 #

🔴DECODING AFIB MECHANISMS: A DUAL THREAT TO RHYTHM STABILITY⚡ Atrial fibrillation (AFib) is driven by two distinct electrophysiological pathways. Identifying the dominant mechanism is key to precision therapy. -🔥 PULMONARY VEIN-DRIVEN AFIB Source: Ectopic foci in pulmonary veins (PV), often due to myocardial sleeve arrhythmogenicity. Mechanism: PV triggers initiate AFib via rapid focal discharges, destabilizing sinus rhythm. Intervention: Pulmonary Vein Isolation (PVI) remains gold-standard ab
