1. Primary Functions of a Pacemaker:
• Regulate Rhythm: It monitors the heart's natural electrical activity and intervenes when it detects an irregular beat (arrhythmia).
• Boost Heart Rate: If the heart is beating too slowly (bradycardia), the pacemaker sends impulses to speed it up to a healthy rate.
• Coordination: Multi-chamber pacemakers ensure that the atria and ventricles contract in the correct sequence to maximize pumping efficiency.
2. Identifying the Non-Function: A pacemaker is a therapeutic and regulatory device, not a diagnostic imaging tool. It does not have the hardware (like transducers or radiation sources) required to
generate images of the heart. Imaging is the role of devices like Echocardiograms (ultrasound), MRI, or CT scanners.
