As a medical professional with expertise in cardiology, I can guide you through the general steps involved in performing a cardioversion, which is a procedure used to restore the normal rhythm of the heart in patients with certain types of abnormal heart rhythms, known as arrhythmias.
English Answer:
1. Preparation: The patient is prepared by obtaining informed consent and ensuring they have fasted for a specific period. Anesthesia may be administered to ensure the patient's comfort during the procedure.
2. Monitoring: Continuous ECG monitoring is initiated to assess the heart's rhythm and to ensure safety throughout the procedure.
3. Sedation: Although not always necessary, sedation may be used to help the patient relax, especially if they are anxious or if they have not undergone the procedure before.
4. Placement of Electrodes: Electrodes are placed on the patient's chest to deliver the electrical shock. The exact placement can vary depending on the type of cardioversion being performed (synchronized or unsynchronized).
5. Synchronization: For a synchronized cardioversion, the device is set to deliver the shock in sync with the patient's QRS complex to avoid the vulnerable period of the heart cycle.
6. Energy Selection: The appropriate amount of energy is selected based on the type of arrhythmia and the patient's size. Lower energy levels are typically used for synchronized cardioversion, while higher levels may be necessary for unsynchronized.
7.
Delivery of Shock: The operator charges the defibrillator and then delivers the shock. The patient may feel a brief, intense jolt followed by a sensation of the heart "resetting."
8.
Post-Shock Assessment: After the shock is delivered, the ECG is monitored to confirm that the heart rhythm has been restored to normal. If the initial shock is not successful, additional shocks may be delivered at higher energy levels.
9.
Recovery: Once the procedure is complete and the heart rhythm is stable, the patient is monitored for a period before being discharged, with follow-up appointments scheduled as necessary.

作为一位在心脏病学领域具有专业知识的医疗专家，我可以指导您完成心脏复律的一般步骤，这是一种用于恢复某些心律失常患者心脏正常节律的程序。
1. 准备： 通过获取知情同意并确保患者已经禁食了一段时间来准备患者。可能会给予麻醉以确保患者在手术期间的舒适。
2. 监测： 开始连续的心电图(ECG)监测，以评估心脏的节律，并确保在整个手术过程中的安全。
3. 镇静： 虽然并非总是必要，但可能会使用镇静剂帮助患者放松，特别是如果他们感到焦虑或之前没有进行过该手术。
4. 放置电极： 在患者胸部放置电极以传递电击。根据执行的心脏复律类型（同步或非同步），确切的放置位置可能会有所不同。
5. 同步化： 对于同步心脏复律，设备被设置为与患者的QRS波群同步传递电击，以避免心脏周期中的易损期。
6. 能量选择： 根据心律失常的类型和患者的体型选择适当的能量水平。同步心脏复律通常使用较低的能量水平，而非同步可能需要更高水平的能量。
7.
传递电击： 操作者给除颤器充电，然后传递电击。患者可能会感觉到短暂的强烈冲击，随后是心脏“重置”的感觉。
8.
电击后评估： 电击传递后，监测ECG以确认心脏节律已恢复正常。如果初次电击不成功，可能会以更高的能量水平传递额外的电击。
9.
恢复： 一旦手术完成并且心律稳定，患者将被监测一段时间，然后出院，并安排必要的后续预约。

During cardioversion, your heart and blood pressure are monitored and a short-acting sedative is given. Then an electrical shock is delivered to your chest wall through paddles or patches that stops the abnormal heartbeat and allows your heart to resume a normal rhythm.
