Arne Larsson in Sweden became the first patient to receive a long-term implantable pacemaker. This pacemaker, also developed by Senning and Elmqvist, marked the beginning of modern pacemakers.

1960 - First silicone pacemaker:

Pacemakers are introduced that can switch between different stimulation modes and adjust their rhythm in response to the patient's activities, improving quality of life.

1990 - Magnetic Resonance Imaging (MRI) Compatible Pacemakers:

Research and development in the 1990s led to the creation of pacemakers that are safe for use in MRI environments.

2000 - Leadless pacemakers:
