As a medical professional with expertise in cardiology, I can explain the differences between a pacemaker and a defibrillator. Both devices are crucial for the treatment of certain heart conditions, but they serve different purposes and are used to address different issues.
A
pacemaker is a small device that's implanted in the chest or abdomen to help regulate the heartbeat. It's primarily used to treat conditions where the heart beats too slowly (bradycardia). The pacemaker sends electrical impulses to the heart to ensure that it beats at a normal rate. It's a long-term treatment solution for people with chronic heart rhythm problems.
On the other hand, an **implantable cardioverter-defibrillator (ICD)** is a slightly larger device also implanted in the chest. It's designed to correct both slow and fast heart rhythms. However, its primary function is to detect and terminate dangerously fast heart rhythms (tachyarrhythmias) by delivering a high-energy shock to the heart, effectively acting like an internal defibrillator. ICDs are often used in patients at risk of sudden cardiac arrest due to underlying heart disease.
In summary, while both devices are used to manage heart rhythm issues, a pacemaker is used for bradycardia and ensures a regular heartbeat, whereas an ICD is used for tachyarrhythmias and can provide life-saving defibrillation.

If your arrhythmia is serious, you may need a cardiac
pacemaker or an implantable cardioverter
defibrillator (ICD). They are devices that are implanted in your chest or abdomen. A
pacemaker helps control abnormal heart rhythms. It uses electrical pulses to prompt the heart to beat at a normal rate.
