Electrophysiology Procedure
电生理学(EP)研究是一项评估心脏电系统或活动的测试,用于诊断异常心跳或心律失常.
该测试是通过插入导管和导线电极来完成的, which measure electrical activity, through blood vessels that enter the heart.
有关如何提前准备电生理学(EP)研究的信息,请参阅 Preparing for the EP Study.
当你到达十大赌博平台排行榜时,为心电图研究做准备的最后步骤是:
- 为了您的舒适,请尽可能完全清空膀胱. A bedpan or urinal will be available during the procedure. Depending on the length of your precedure, 在手术过程中,可能会插入导尿管以排出膀胱中的尿液.
- 一个小的静脉注射针将被插入你手臂的静脉来给药, if necessary.
The procedure
EP研究在十大赌博平台排行榜的电生理实验室进行, where you'll be placed on an X-ray table. 摄像机、电视屏幕、心脏监测器和各种仪器将在附近. 电极将放置在你的胸部和背部,将你与监测设备连接起来. 将在您的上臂上放置一个血压袖带来监测您的血压.
To prevent infection, 护士会刮干净腹股沟,可能还有插入导尿管的颈部区域. The area will be cleansed with an antiseptic. Sterile sheets will be draped over your body.
找一个舒服的姿势,这样你就可以在手术过程中保持不动. 请不要触摸颈部和腹股沟处的无菌区域.
Depending on the type of study you undergo, you may be given medications intraveniously, administered in your arm, to sedate you or make you sleepy. 这些药物有助于减少你的焦虑,缓解你的不适. 你的十大赌博平台排行榜会告诉你镇静剂是否合适.
局部麻醉将用一根小针麻醉插入导管的部位. 你会感到针刺,可能有刺痛感,持续几秒钟.
One or more catheters, which are thin, long, flexible wires, will be inserted into a large vein in your groin or neck. The catheters will be guided to your heart. 心脏内导管的位置将在屏幕上被监控. You may feel pressure when the catheters are inserted. The incision site is less than a quarter of an inch.
There are two parts to the EP study:
- 记录心脏电信号来评估电功能
- 在控制十大赌博靠谱网络平台下使心脏起搏以引起某些异常节律以供观察
Medications are sometimes used to stimulate your arrhythmia. You may feel your heart racing or pounding. This may make you anxious, but you needn't be alarmed. 十大赌博平台排行榜想诱导引起你问题的异常心律, so they can treat the arrhythmia. If you have any uncomfortable symptoms — such as chest pain, dizziness, shortness of breath, nausea and pain — tell your nurse or doctor.
Your role during the study
Try to remain calm and relaxed. Don't move your arms or legs in the sterile working area. If you feel any discomfort, let your doctors or nurses know immediately, so they can help you get comfortable.
In the controlled environment of the EP laboratory, 诱发性心律失常由训练有素的人员和最先进的设备处理. 这是一个重要的工具,可以让你的十大赌博平台排行榜获得关于你的心律失常的信息,这将有助于防止未来的发生.
After the procedure
Once the EP study is over:
- 取出导管,压在腹股沟和颈部以防止出血.
- 你要静静地躺在床上四到六个小时,让导管位置密封好. Don't move or bend your leg.
- You will be checked frequently. 如果你突然感到疼痛或看到出血部位,立即叫护士.
- 你的十大赌博平台排行榜可能会在测试后分享一些初步结果.
- If you feel well enough, you may be able to eat and drink.

Returning home
出院回家后,请遵循以下指引:
- Limit your activity for the first 24 hours. 第一周不要用力或举起超过10磅的重物.
- If traveling home takes several hours, stop every hour, 伸展你的腿,走几分钟,以防止在你的腿形成血块.
- 如果你发现敷料上有新血,用力按压切口约20分钟. If bleeding continues, 打电话给你的十大赌博平台排行榜或去最近的急诊室,同时仍然施加压力.
- Leave the dressing on until the day after the study. Your nurse will show you how to remove it.
如果你在插入部位的皮肤下看到瘀伤或小肿块,不要担心. It will disappear within three to four weeks.
When to call us
Call your doctor or arrhythmia nurse coordinator if:
- 插入导管的部位摸起来会感到疼痛或发热.
- 你有胸痛、心悸、呼吸急促或头晕.
