Difference between Defibrillator and Pacemaker

There are a few key differences between a defibrillator and a pacemaker. For one, a defibrillator is used to treat life-threatening cardiac arrhythmias, while a pacemaker is used to treat heart failure and other conditions. Additionally, the way they work is different – a defibrillator delivers an electric shock to the heart in order to restore normal rhythm, while a pacemaker uses electrical pulses to help the heart beat regularly. Finally, defibrillators are typically larger and more expensive than pacemakers.

What is Defibrillator ?

A defibrillator is a medical device that delivers a therapeutic dose of electrical energy to the heart muscle. This energy is delivered in the form of short, high-voltage pulses that stimulate the heart to contract. Defibrillation is used in order to terminate ventricular fibrillation and pulseless ventricular tachycardia, which are both life-threatening arrhythmias. Defibrillators can be found in a variety of settings, including hospitals, ambulances, and public places such as airports. AEDs, or automated external defibrillators, are designed for use by laypersons with little or no medical training. When used properly, defibrillators can be extremely effective in saving the lives of people suffering from cardiac arrest.

What is Pacemaker?

A pacemaker is a brand of implantable cardiac pacemaker manufactured by Medtronic. It was first introduced in 1998 and quickly became the most popular type of pacemaker in the United States. Pacemakers are devices that are implanted under the skin to help regulate the heart’s rhythm. They use electrical pulses to stimulate the heart and keep it beating at a regular rate. Pacemakers can be used to treat a variety of heart conditions, including bradycardia (a slow heart rate) and tachycardia (a fast heart rate). Pacemakers are typically implanted through a small incision in the chest, and the surgery is usually performed on an outpatient basis. Recovery from surgery is typically quick, and most people are able to return to their normal activities within a week. Pacemakers can last for many years, and they typically do not require any special care or maintenance.

Difference between Defibrillator and Pacemaker

A Defibrillator is a device that is used to deliver an electric shock to the heart in order to restore a normal rhythm. This can be used in cases of cardiac arrest in order to save the patient’s life. A Pacemaker is a device that is used to help regulate the heart rate. This is often used in cases where the patient has an irregular heart rhythm. Pacemakers are often implantable, which means that they are placed under the skin and connected to the heart. Defibrillators are usually external devices that are used in emergency situations. Both Defibrillators and Pacemakers can be lifesaving devices for patients with heart conditions.


The main difference between a defibrillator and a pacemaker is that a defibrillator is used to shock the heart back into a normal rhythm in cases of cardiac arrest, while a pacemaker is used to help regulate the heartbeat in people with arrhythmia. If you’re experiencing heart problems, it’s important to know which device is best for you and your unique situation. Talk to your doctor about which option would be best for you.
