Final answer:
Ventricular fibrillation is a deadly arrhythmia treated with defibrillation. External Automated Defibrillators are vital in public areas, guiding users through cardiac defibrillation. The heart's susceptibility to arrhythmias from electrical currents necessitates safety precautions.
Step-by-step explanation:
Ventricular Fibrillation and Its Treatment:
Ventricular fibrillation is a type of heart arrhythmia characterized by uncontrolled, irregular heartbeats that prevent the ventricles from pumping blood effectively. It is a medical emergency often indicated by a 'code blue' in hospitals. Without prompt treatment, it may lead to brain death within minutes. The most effective treatment is defibrillation, which applies an electrical charge to the heart using paddles or pads to reset the heart's rhythm.
External Automated Defibrillators (EADs) are now commonplace in public areas such as airports and restaurants due to their ability to assist even nonmedical personnel in providing life-saving cardiac defibrillation. These devices contain instructions to guide a user through the process in an effort to reestablish normal sinus rhythm and potentially save a life.
Various factors such as electrical shocks can lead to ventricular fibrillation; however, large currents may arrest the heart temporarily, allowing it to 'restart' with a normal rhythm. It is essential to have safety precautions around the heart, especially during surgical procedures, due to its susceptibility to electrical currents leading to arrhythmias.
