常见问题:植入式心律转复除颤器
很多人都有问题 植入式心律转复除颤器 — how they work and why a doctor might decide to offer one as part of treatment for a 心律失常. 这里有一些常见的问题和答案.
- ICD能治愈我的心律问题吗?
- ICD是治疗所有心律失常的正确方法吗?
- 体外除颤器的电击会痛吗?
- 如果有人在我被体外除颤器电击时碰了我一下,他们会怎么样?
- 植入设备后,我能恢复到以前的生活吗?
- 除颤器应该放在哪里?
- 植入手术是开胸手术吗?
- ICD是如何供电的?
- 十大赌博平台排行榜多久检查一次我的ICD?
- 带着除颤器的人能靠近微波炉吗?
不,不会的. Cure means to completely and permanently eliminate the condition and that's not what an ICD does. 在某些情况下, 电生理学家可以提供治疗节律紊乱的方法, 有时通过表演 消融.
An implantable defibrillator is most commonly used as a part of a patient's treatment. 如果你的心律变差,它会立即起作用. 每次问题发生时,它都会处理问题. Many doctors use an ICD in combination with rhythm control medications called antiarrhythmics. 我们的目标, 在这种情况下, is to use medication to keep the rhythm from getting too fast and to use the ICD as a "failsafe" device to protect you if your heart rate increases dangerously despite the medication.
No. Implantable cardioverter defibrillators are intended to treat very serious rhythm problems that can arise in the lower portion of the heart, 叫做心室. In the future, ICDs will be available that can be used for patients with other rhythm problems.
良好的心律控制通常可以通过药物单独实现. If your symptoms worsen or if the problem is persistent or potentially dangerous, 你的十大赌博平台排行榜可能会做手术 电生理(EP)研究 了解更多关于节奏和最好的治疗方法. 在某些情况下, an electrophysiologist may not need a study if the problem and its solutions are clear. If an ICD is one of the solutions, your doctor will know and discuss it with you.
Most patients who have received shocks from their ICDs describe them as startling, 颠簸不安, 但并不痛苦. 原因很容易理解. ICD通过电击来防止心律过快. 设备可以识别节奏, 哪个会引起不适——头晕, 头晕, 心慌, 一种“快要晕过去”的感觉,然后突然, 体外除颤器休克使心律恢复正常. 这种震动是一种强大的力量,可以毫不拖延地控制心脏.
他们不会有事的. A shock from an ICD is less powerful than a shock given externally such as shocks given by paramedics or emergency room workers who use "paddles" on the chest, 叫去颤. 当我们给某人体外除颤器时, we use a great deal of energy to be certain there is enough to travel to the heart and do the job. ICD通过与心脏相连的电线直接对心脏进行电击. 它可以用比外部设备少得多的能量实现同样的冲击. 逃逸到表面的能量, 哪里会有人碰我们, 是很难检测到并且完全无害的吗.
在很多情况下, 一旦治疗开始控制你的心律, 生活可以开始恢复正常. In addition to ICDs, treatments include medication, 消融, a pacemaker or a combination of these. 大多数患者重返工作岗位, 学校和他们平时的活动包括开车, 性关系和锻炼, 一旦他们的十大赌博平台排行榜确认他们安全了. How long it takes depends on the individual patient and the other medical problems you may have.
过去,当icd更大时,它们被植入腹部. 现在它们变小了, 十大赌博平台排行榜通常把它们植入胸腔, 最常见的是在锁骨或锁骨以下, 在胸部的右侧或左侧. 你可以在皮肤下感觉到并看到设备的轮廓.
No. Implanting an ICD is much simpler than it was a few years ago and often takes less than an hour.
The doctor who performs this procedure is the best source of information about what type of anesthesia will work best for you. 通常来说, 病人使用镇定剂保持轻度睡眠状态效果很好, in combination with local anesthetic to numb the area where the device is implanted. The incision is usually a small one — three or four inches wide — and travels horizontally on the chest. ICD就位并关闭切口后, 十大赌博平台排行榜用绷带保护伤口.
大多数患者会在大约一周的时间里感到疼痛. 十大赌博平台排行榜 advise patients with new ICDs to avoid getting the site wet for several days after it has been implanted.
植入式心律转复除颤器是由电池供电的. The variety used has been chosen because of its long service period and the very predictable way in which its power is gradually used. 如果ICD产生了很多冲击, 它会比那些很少提供治疗的人更容易衰竭. 大多数icd可以使用5年甚至更长时间. Checking the battery is an important part of any evaluation of the device and doctors are careful to do this as a portion of their routine follow-up.
A normal clinic visit to the electrophysiologist or cardiologist usually includes an inspection of the device. 这意味着我们使用一个设备, 叫做程序员, “要求”ICD显示其电池电压, 其设置, any rhythm disturbances it has detected and any therapy it has delivered since the last visit.
Long before the battery is ready to expire and long before the performance of the ICD changes in any way, an exam like this will show the doctor that the time is approaching to consider a replacement ICD. 在这一点上, a brief hospital stay is arranged — typically no more than one or two days — to allow the doctor to remove the old ICD and replace it with a fresh one. 置换手术通常比原植体更简单, 这样十大赌博平台排行榜和病人之间的时间就更少了.
十大赌博平台排行榜对此意见不一. Some say they prefer to see their ICD patients every two months or even more often when they feel the heart rhythm needs especially close observation. 其他人则要求他们的病人每四到六个月来一次. 这在节律相当稳定的患者中更为常见.
是的. 几年前, 当时的icd和微波炉的制造方式非常不同, 一些icd在老式微波炉面前反应不佳. 因此,icd经过了改进,不再受微波炉的影响. 起搏器也是如此. 然而,十大赌博平台排行榜建议ICD患者避免一些事情,包括:
- 非常强大的磁铁, such as those you might find in a junkyard to lift discarded automobiles or contained within the cases of powerful stereo speakers. 小, weaker magnets — like those used to hold notes on a refrigerator or those in telephone receivers — pose no difficulty.
- Very powerful electromagnetic fields generated by the equipment used for magnetic resonance imaging (MRI).
- 汽车点火系统附近的电磁场.
The main concern is that a very strong electromagnetic field temporarily deactivates the ICD. 这种效果只会持续到病人还在现场, returning the ICD to full function as soon as you move away from the magnetism. However, your doctor doesn't want your device's operation suspended even briefly.
