FAQ: Implantable Cardioverter Defibrillators
Many people have questions about implantable cardioverter defibrillators (ICDs) -它们是如何工作的,为什么十大赌博平台排行榜可能会决定提供一个作为治疗的一部分 心律失常. Here are a few common questions and answers.
- Will an ICD cure my heart rhythm problem?
- Is an ICD the right treatment for all rhythm disturbances?
- Do shocks from an ICD hurt?
- If someone touches me when I get an ICD shock, what will happen to them?
- After the device is implanted, can I return to life as it was before?
- Where will the defibrillator be placed?
- Is the implant procedure an open heart operation?
- ICD是如何供电的?
- How often will my doctor check my ICD?
- Can people with defibrillators go near microwave ovens?
Will an ICD cure my heart rhythm problem?
不,不会的. 治愈意味着完全和永久地消除疾病,这不是ICD所能做的. 在某些情况下, an electrophysiogist can provide a cure for a rhythm disturbance, sometimes by performing an 消融.
植入式除颤器是最常用的患者治疗的一部分. It acts instantly if your heart rhythm changes for the worse. It treats the problem, each time it occurs. 许多十大赌博平台排行榜将ICD与抗心律失常药物结合使用. 我们的目标, 在这种情况下, 是使用药物来防止心率过快,并使用ICD作为“故障保险”装置来保护你,如果你的心率在药物的作用下危险地增加.
Do ICDs treat all rhythm disturbances?
No. 植入式心律转复除颤器旨在治疗心脏下部可能出现的非常严重的心律问题, 叫做心室. 在未来,icd将可用于其他节律问题的患者.
Good heart rhythm control often can be achieved with medication alone. 如果症状恶化,或者问题持续存在或有潜在危险, your doctor may perform an electrophysiology (EP) study to learn more about the rhythm and the best treatments to deal with it. 在某些情况下, 如果问题及其解决方案是明确的,电生理学家可能不需要研究. 如果ICD是一种解决方案,你的十大赌博平台排行榜会知道并与你讨论.
大多数受到过icd电击的病人都说很震惊, 颠簸不安, 但并不痛苦. It's easy to understand why. The ICD delivers a shock to prevent a dangerously fast heart rhythm. The device recognizes the rhythm, which may cause discomfort — dizziness, 头晕, 心慌, an "about-to-faint" feeling — and then suddenly, the ICD shock brings the rhythm back to normal. The jolt is a powerful one to control the heart without delay.
If someone touches me when I get an ICD shock, what will happen to them?
Nothing will happen to them. 来自ICD的电击比外部施加的电击更弱,例如护理人员或急诊室工作人员在胸部使用“电击棒”施加的电击, 叫去颤. When we defibrillate someone externally, 我们使用大量的能量来确保有足够的能量到达心脏并完成工作. The ICD shocks the heart directly, through wiring connected to the heart. It can achieve the same shock with far less energy than external devices. The energy that escapes to the surface, where someone might touch us, is very difficult to detect and completely harmless.
After the device is implanted, can I return to life as it was before?
在很多情况下, once treatment begins to control your heart rhythm, life can begin to return to normal. 除icd外,治疗方法还包括药物、消融术、起搏器或这些方法的组合. Most patients return to work, school and their usual activities including driving, sexual relationships and exercise, once their doctors see that they're safe. 需要多长时间取决于个别病人和你可能有的其他医疗问题.
Where will the defibrillator be placed?
In the past, when ICDs were much larger, they were implanted in the abdomen. 现在它们变小了, doctors usually implant them in the chest, most often below the clavicle or collarbone, on the right or left side of the chest. You may feel and see the outline of the device under the skin.
Is the implant procedure an open heart operation?
No. 植入ICD比几年前要简单得多,通常需要不到一个小时.
做这个手术的十大赌博平台排行榜是最好的信息来源,告诉你哪种麻醉对你最有效. 通常来说, patients do very well with sedation to keep them in a light state of sleep, 结合局部麻醉剂麻醉植入装置的部位. 切口通常很小,三到四英寸宽,在胸部水平移动. After the ICD is in place and the incision is closed, the doctor applies a bandage to protect the site.
Most patients notice some soreness for about a week. 十大赌博平台排行榜建议新植入式心脏除颤器的患者在植入式心脏除颤器植入后的几天内避免使部位浸湿.
Implantable cardioverter defibrillators are powered by batteries. 选择使用的品种是因为它的使用周期长,而且它的能量逐渐被使用的方式非常可预测. If an ICD delivers a great many shocks, it will wear out sooner than one that seldom provides therapy. Most ICDs last five years and often more. 检查电池是任何设备评估的重要组成部分,十大赌博平台排行榜会谨慎地将其作为例行随访的一部分.
对电生理学家或心脏病专家的正常门诊访问通常包括对设备的检查. This means that we use a piece of equipment, 叫做程序员, to "ask" the ICD to show its battery voltage, 其设置, 它检测到的任何节律紊乱以及自上次就诊以来提供的任何治疗.
早在电池准备到期之前,早在ICD的性能以任何方式改变之前, 这样的检查将告诉十大赌博平台排行榜是时候考虑更换ICD了. 在这一点上, 十大赌博平台排行榜会安排一段短暂的住院时间——通常不超过一到两天——以便取出旧的ICD,换上新的. Replacement procedures are often simpler than original implantations, and take the doctor and patient even less time.
How often will my doctor check my ICD?
十大赌博平台排行榜 vary in their opinions about this. 一些十大赌博平台排行榜说,他们更愿意每两个月见一次ICD患者,甚至在他们觉得需要密切观察心律时更频繁. Others ask their patients to return every four to six months. This is more common among patients whose rhythms are quite stable.
Can people with defibrillators go near microwave ovens?
是的. 几年前, when both ICDs and microwave ovens were made very differently, some ICDs reacted badly in the presence of old-style microwave ovens. As a result, ICDs were modified and are no longer affected by microwave ovens. This also is true for pacemakers. However, doctors advise ICD patients to avoid a few things, including:
- 非常强大的磁铁, 比如那些你可能在垃圾场找到的用来提起废弃汽车的,或者装在强力立体声扬声器盒子里的. 小, 较弱的磁铁——比如冰箱上用来固定便条的磁铁或电话接收器上的磁铁——不会造成任何困难.
- 磁共振成像(MRI)设备产生的非常强大的电磁场.
- The electromagnetic field near an automobile ignition system.
主要的问题是,非常强的电磁场会暂时使ICD失效. This effect persists only as long as the patient is in the field, 一旦远离磁性,ICD就会恢复正常功能. 然而,你的十大赌博平台排行榜不希望你的设备的操作暂停,即使是短暂的.
