What types of defibrillators are there?

What types of defibrillators are there?

Internal & external: Implantable (internal) defibrillators remain in the body, whereas external defibrillators are the boxes with paddles that you see on tv shows. They both shock the heart out of life-threatening cardiac arrest rhythm if need be. There are automated external units that lay people can use; you put paddles on person's chest and the machine determines the rhythm and speaks commands to give a shock. ...Read more

What is a defibrillator?

Multiple types: External defibrillators are used on an emergency basis to convert life threatening rapid ventricular arrhythmias. These are also available in a wearable form called a life vest. There are also implantable defibrillators inserted in survivors of sudden death or those at risk of sudden death. ...Read more

How can you use a defibrillator?

Variety of ways: There are two kinds of defibrillators, internal and external. Internal defibrillators are implanted under the skin similar to a permanent pacemaker. This type of defibrillator works automatically and does not require human intervention. External defibrillators are found in hospitals and in public areas. These are manually applied to the outside of the chest. ...Read more

How does a defibrillator function?

How does a defibrillator function?

Electrical system: A defibrillator causes all myocardial (heart) cells to become depolarized at the same time. This extinguishes the abnormal arrhythmia, and allows the natural cardiac pacemaker to kick back in. This requires a large electrical current, to make sure all myocardial cells get activated at the same time. ...Read more

Can I use defibrillator on myself?

Probably not.: Most heart rhythms that would require a defibrillator will probably cause loss of consciousness quickly - so you would be unconscious prior to being able to hook up the defibrillator and set it off. ...Read more

Why would a defibrillator not work?

Debirillator: A defibrillator is an electric device and subject to all the failure modes of any electric device. Assuming the device has a good power source and all components are working and it delivers the shock appropriately, there is no guarantee the heart will respond. If the cardiac status is too far gone electrophysiologically the rhythm won't convert. ...Read more
