Final answer:
Rapid defibrillation involves using a defibrillator to deliver a strong electrical shock to the heart, terminating ventricular arrhythmias and allowing the heart's natural pacemaker to restore a normal rhythm, often after CPR. This intervention is critical during cardiac arrest and AEDs are widely available for public use.
Step-by-step explanation:
Understanding Rapid Defibrillation
Rapid defibrillation works by delivering a large electrical shock to the heart through a set of paddles or pads placed on a patient's chest. This electrical shock is necessary to treat cardiac arrest that occurs due to ventricular fibrillation, which is an irregular and rapid heart rhythm. The shock from a defibrillator can stop the arrhythmia, allowing the body's natural pacemaker to restore a normal heart rhythm. In cases of cardiac arrest, it is often accompanied by the application of CPR before the defibrillation. Ambulances and many public places are equipped with automated external defibrillators (AEDs) that can analyze a patient's heart rhythm and deliver the appropriate shock, making it possible for even non-medical personnel to provide life-saving treatment.
