How to take first aid measures for ventricular fibrillation

The so-called ventricular fibrillation is what is often referred to as ventricular fibrillation in clinical practice. When ventricular fibrillation occurs, it must be defibrillated in time, otherwise it will directly lead to the patient's death. The reason why ventricular fibrillation occurs is related to coronary heart disease, myocardial ischemia, drug poisoning, allergies, etc. However, no matter what causes ventricular fibrillation, the first task for doctors is to take emergency measures for ventricular fibrillation. The specific emergency methods are as follows:

Ventricular fibrillation is a fatal rapid ventricular arrhythmia. When ventricular fibrillation occurs, the heart stops effectively contracting and relaxing. The ventricles completely lose their ability to pump blood, blood circulation is interrupted, heart sounds disappear when auscultated, the pulsation of the large arteries cannot be felt, the pupils are dilated, and the light reflex disappears. Once ventricular fibrillation occurs, it generally does not stop on its own. Defibrillation must be performed immediately and first aid must be performed every second. Only then can the patient be successfully resuscitated. Otherwise, if the rescue time is delayed, the patient will often die quickly.

Ventricular fibrillation is the irregular contraction of the ventricular muscle, which will be shown on the electrocardiogram. It can cause the myocardium to lose its blood-excreting function, heart sounds and pulse to disappear, and blood perfusion to organs and tissues such as the heart and brain stops, leading to sudden cardiac death. Once ventricular fibrillation is confirmed, electrical shock should be performed promptly. The energy used for the first asynchronous defibrillation is generally 200-350J. If ineffective, lidocaine 50-100 mg or bromocaine 5-10 mg/kg can be injected intravenously to lower the defibrillation threshold and increase the success rate of the second defibrillation.

This article has introduced and analyzed the first aid measures for ventricular fibrillation. Of course, the specific operation methods for doctors still need to be determined according to the patient's condition, but no matter what, I hope that everyone can have a definition of ventricular fibrillation and know how harmful this disease is.
