Examples of defibrillation in the following topics:
-
- Some combine a pacemaker and defibrillator in a single implantable device.
- Sometimes devices resembling pacemakers, called implantable cardioverter defibrillators (ICDs), are implanted.
- An ICD has the ability to treat many types of heart rhythm disturbances by means of pacing, or defibrillation.
-
- These palpitations have also been known to be caused by atrial/ventricular fibrillation, wire faults, and other technical or mechanical issues in cardiac pacemakers/defibrillators.
- Defibrillation differs in that the shock is not synchronized.
- Often, more electricity is required for defibrillation than for cardioversion.
- In most defibrillation, the recipient has lost consciousness so there is no need for sedation.
-
- Administration of an electric shock to the subject's heart, termed defibrillation, is usually needed in order to restore a viable or "perfusing" heart rhythm.
- Defibrillation is only effective for certain heart rhythms, namely ventricular fibrillation or pulseless ventricular tachycardia, rather than asystole or pulseless electrical activity.
-
- Echocardiography may also aid in deciding what treatments will help the patient, such as medication, insertion of an implantable cardioverter-defibrillator, or cardiac resynchronization therapy.
-
- These can also be caused by atrial/ventricular fibrillation, wire faults, and other technical or mechanical issues in cardiac pacemakers/defibrillators.
