💓 AFib vs. VFib 💓 ⚡ Atrial Fibrillation (AFib): The heart’s upper chambers (atria) quiver, leading to an irregular heartbeat. Symptoms can include palpitations, fatigue, or dizziness. While not immediately life-threatening, it increases the risk of stroke. ⚡ Ventricular Fibrillation (VFib): The heart’s lower chambers (ventricles) quiver chaotically, preventing blood from pumping to the body. This is a medical emergency requiring immediate defibrillation to save a life. . Like and save this vid
