A pacemaker is a compact electronic device implanted in your chest, just below the collarbone, designed to help regulate your heart rate. It is typically recommended for individuals experiencing dangerously low heart rates, a condition known as bradycardia. By sending electrical impulses to the heart, a pacemaker helps ensure it beats at a normal rate, improving blood flow and overall heart function.

Types of pacemakers

There are three main types of pacemakers:

• Single Chamber Pacemakers: These consist of a single lead connected to one heart chamber, usually the right ventricle. This type is often used when the heart’s upper chambers are functioning properly.
• Dual-Chamber Pacemakers: These have two leads that connect to both the atrium (upper chamber) and the ventricle (lower chamber). This configuration allows for better coordination of heart contractions, which can be beneficial for patients with specific rhythm issues.
• Biventricular Pacemakers: Also known as cardiac resynchronization therapy (CRT) devices, these pacemakers have three leads that stimulate both ventricles simultaneously. This approach is particularly useful for patients with heart failure, as it helps improve the efficiency of the heart’s pumping action.
