What is the primary goal of pacemaker insertion?

To replace damaged heart valves

To control heart rate and rhythm in patients with arrhythmia

The primary goal of pacemaker insertion is to control heart rate and rhythm in patients with arrhythmia. Pacemakers are devices that provide electrical stimulation to the heart to ensure it beats at a normal rhythm, effectively preventing the heart from beating too slowly (bradycardia) or irregularly. In patients with certain types of arrhythmias, the heart's electrical signals are disrupted, which can lead to symptoms such as dizziness, fatigue, or fainting. By delivering regular electrical impulses, a pacemaker helps maintain an optimal heart rhythm, improving blood flow and overall cardiac function.

The other options do not specifically address the core function of a pacemaker. While managing heart workload and improving oxygen supply are important aspects of overall cardiac health, these are typically addressed through different interventions or treatments, not through the insertion of a pacemaker.
