Final answer:
b. False The shock during synchronized electrical cardioversion does not occur exactly when the 'deliver shock' button is pressed but is instead synchronized with the patient's cardiac cycle to prevent further arrhythmias.
Step-by-step explanation:
The statement that the shock during synchronized electrical cardioversion occurs at the exact time that you press the "deliver shock" button is false. In synchronized cardioversion, the defibrillator is designed to deliver a shock that is timed with the patient's cardiac cycle, specifically during the R wave of the QRS complex in an electrocardiogram (ECG), to avoid the induction of ventricular fibrillation. The defibrillator uses sensors to detect the patient's heart rhythm and deliver the charge when it is safe and most effective. This precision in timing is crucial since the goal of cardioversion is to reset the heart's rhythm without causing additional arrhythmias.
When performing synchronized electrical cardioversion, the shock does not occur at the exact time that you press the "deliver shock button." Rather, the shock is delivered at a specific point in the cardiac cycle, usually during the R wave of the QRS complex on the electrocardiogram (ECG). By delivering the shock at this specific time, it maximizes the effectiveness of the treatment and reduces the risk of causing harmful arrhythmias. Synchronized electrical cardioversion is commonly used to treat certain types of abnormal heart rhythms, such as atrial fibrillation.
