As an expert in the field of medical science, particularly in emergency and critical care, I can provide an explanation of the term "synchronized shock." Synchronized shock, also known as synchronized cardioversion, is a procedure used to restore a normal heart rhythm in patients with certain types of abnormal heart rhythms, or arrhythmias. During this procedure, a controlled electrical shock is delivered to the heart. The key aspect of synchronized shock is that it is timed to the patient's heartbeat, specifically during the absolute refractory period of the cardiac cycle, which is when the heart is not responsive to electrical signals. This timing ensures that the shock is delivered when the heart is in a state that will allow it to be effectively reset to its normal rhythm. The procedure is typically performed under sedation or anesthesia to ensure patient comfort. It is a non-surgical treatment that can be a life-saving intervention for individuals with life-threatening arrhythmias. Now, let's translate this into Chinese: read more >>

Synchronized cardioversion is a LOW ENERGY SHOCK that uses a sensor to deliver electricity that is synchronized with the peak of the QRS complex (the highest point of the R-wave). When the ��sync�� option is engaged on a defibrillator and the shock button pushed, there will be a delay in the shock.read more >>
