In simple words: This code represents a very serious heart rhythm problem where the lower chambers of the heart (ventricles) quiver instead of beating regularly, which prevents the heart from pumping blood effectively. This is a life-threatening emergency.

This code signifies a rapid, irregular, and unsynchronized contraction of the ventricles of the heart, resulting in the inability of the heart to effectively pump blood. This condition can be life-threatening if not treated promptly.

Example 1: A patient presents to the emergency department with sudden onset of palpitations, shortness of breath, and dizziness. An ECG reveals ventricular fibrillation. The patient is immediately defibrillated and stabilized., A patient with a history of coronary artery disease experiences an episode of ventricular fibrillation during a routine stress test. The patient is treated with medication to control the arrhythmia and prevent recurrence., A patient with idiopathic ventricular fibrillation, a genetic condition predisposing them to this arrhythmia, undergoes implantation of an implantable cardioverter-defibrillator (ICD) to automatically detect and terminate any future episodes of ventricular fibrillation.

Documentation should include ECG findings confirming the diagnosis, description of the episode, any associated symptoms, treatment provided (e.g., defibrillation, medications), and any underlying conditions that may have contributed to the event.
