Defibrillators

Criteria for Defibrillators

The cardiac defibrillator is a life-saving device used to give the heart a controlled electric shock to jolt it back to beating normally. According to a May 2004 study published in "Medscape Cardiology," cardiac defibrillators are best used in patients with severe types of heart conditions. The use of defibrillators in such patients can ultimately help prevent further heart damage such as sudden heart death, according to a statement released by Medscape Internal Medicine in January 2005.

How to Exercise With a Defibrillator

According to the American Heart Association, many individuals with sustained tachycardia, or irregular heart rate, benefit from the use of a implantable cardioverter defibrillator -- ICD -- or pacemaker. These devices can detec...

Types of Heart Defibrillators

Heart defibrillators are used to treat cardiac arrest--a disease in which the heart stops beating due to several reasons. They are used to treat cardiac arrest caused by irregular heart beats--heart beats that are too fast or e...

Cardiac Defibrillator Types

... by abnormal heart beats such as fast or erratic heart beats. Treatment for cardiac arrest caused by irregular heart beats is aimed at getting the heart to beat regularly and several types of cardiac defibrillators may be us...

Types of Implantable Cardio Defibrillator

An implantable cardio defibrillator, or ICD, is a small electrical impulse generator. The ICD is traditionally used in patients who are at risk for serious cardiac attacks which can lead to sudden cardiac death. These attacks...

Heart Defibrillator Side Effects

A heart defibrillator controls the heart rhythm. It sends an electrical shock through the heart when it beats too quickly or becomes irregular, notes the University of Chicago Medical Center. An electrical shock is used to retu...

Defibrillator Precautions

... a medical emergency, a cardiac arrest victim has the highest possibility of surviving if revived within four minutes, according to the American College of Emergency Physicians. An automated external defibrillator, or AED, i...

Defibrillator Procedures

According to the American Heart Association, defibrillation does not restart the heart; it stuns the the heart briefly to allow the heart's natural pacemakers to resume electrical activity. Knowing the proper procedure for defi...

Types of Defibrillators

... known as the sinus node, produce electrical impulses that trigger the heart to contract rhythmically. Arrhythmia, or abnormal heart rhythm, causes the heart to pump either too quickly or too slowly. Defibrillation describes...

What Are the Benefits of Defibrillators?

Prior to the advent and use of heart defibrillators, the survival rate from a sudden cardiac arrest was very poor. The only tools that rescuers and non-medical trained bystanders had was CPR. Today defibrillators are availabl...

What Is an Automatic Internal Cardiac Defibrillator?

Automatic internal cardiac defibrillators are more commonly known as implantable cardioverter defibrillators, or ICDs. This life-saving tool can prevent sudden cardiac death in patients at high risk for the development of fata...

Defibrillator Risks

There are three kinds of defibrillators--machines designed to deliver a shock to the heart when it goes into a life threatening rhythm. One type, the external defibrillator, is used in and out of the hospital. External defibril...

How Is a Defibrillator Implanted?

Internal defibrillators are similar in size and structure to pacemakers. They monitor the rhythm of the patient's heart and can give a small electric shock if the heart starts to develop an abnormal rhythm, resetting the heart'...

How Does a Biphasic Defibrillator Work?

The heart is predominantly made up of muscle (also known as cardiac muscle). Like all muscles, cardiac muscles contract in response to electrical stimulation. The contraction of cardiac muscle is carefully controlled to ensure ...

Complications of Implantable Defibrillators

Implantable Cardioverter Defibrillators (ICDs) are a class of electronic devices manufactured to deliver currents of electricity to the heart in response to abnormal heart rate. This usually is enough to "shock" the heart back ...

Types of Implantable Cardioverter Defibrillators

An implantable cardioverter defibrillator (ICD) is a type of electronic device that constantly monitors heart rate and rhythm. It is usually implanted in the chest area right near the heart, and when it senses an abnormal rate ...

How Is a Defibrillator Used?

A defibrillator or automated external defibrillator is a device that can restore normal heart rhythm to a person whose heart has stopped. The defibrillator is designed to be used by the lay public while waiting for medical prof...

How Does an Implanted Defibrillator Work?

Your heart contains its own pacemaker called the sino-atrial (SA) node. Your SA node initiates electrical signals that travel throughout your heart muscle to tell it when to beat. It signals your heart muscle to speed up or slo...

How Defibrillators Work

...ontract, it can't pump blood out to the body. The brain and tissues become starved for oxygen, and the body eventually dies. The heart is unable to "snap out of it" and return to its normal rhythm. A defibrillator jolts the ...

Implanted Cardiac Defibrillators

An implanted cardiac defibrillator (ICD) is a small device that can be considered the ultimate insurance policy for a patient with severe heart disease. If a patient suffers a heart attack that injures the muscle and reduces ...
