⚕️Dr. stranger 👩‍⚕️ on Instagram: "👉What is pacemaker? ✨A pacemaker is a small electronic device that helps control abnormal heartbeats. It is usually implanted under the skin near the chest and sends electrical signals to the heart to keep it beating at a normal and steady rate. Pacemakers are commonly used when the heart beats too slowly or irregularly. . . #reelsinstagram #viralreels #instatrending #explorepage #instareelsindia❤️"
