1. What is the first internal implantation?1958 by Rune Elmqvist and Åke Senning
2. What is the primary pacing technologies?Single-chamber, dual-chamber, and biventricular (CRT) pacing
3. What is a pacemaker and how does it help the heart?A pacemaker is a tiny device that sends electrical signals to keep the heart beating at the right pace. It helps the heart stay strong and steady when it needs a little extra help.
4. How did doctors first start using pacemakers?In the 1950s doctors tried big external machines, but in 1958 a small internal pacemaker was put inside a person, making it easier to use. This made heart care safer and more reliable.

Arrhythmia: An irregular heartbeat, either too fast, too slow, or with an abnormal rhythm.
Cardiac Resynchronization Therapy (CRT): A type of pacemaker therapy that helps the heart's lower chambers beat in a more coordinated way.
Electrophysiology: The study of the electrical properties of biological cells and tissues, particularly in the heart.
