⚡️Atrial Fibrillation with Rapid Ventricular Response (RVR): What You Need to Know ⚡️ In Afib, the atria depolarize chaotically, sending irregular and disorganized signals to the AV node. When these signals overwhelm the AV node, the result is a rapid ventricular response — often exceeding 100 bpm — leading to Afib with RVR. Clinically, patients may present with palpitations, dyspnea, hypotension, or even signs of heart failure. It’s crucial to recognize this early to prevent hemodynamic instabi
