植入式医疗器械
节奏控制
- Implantable cardioverter defibrillator (也被称为 ICD) — An ICD is a battery-powered device placed under the skin that keeps track of your heart rate. If an ICD detects a heart rhythm that is chaotic or much faster than normal, it will send an electrical shock to the heart to bring the rhythm back to normal.
- 起搏器 (也被称为 人工心脏起搏器) — A small battery-operated device that helps the heart beat in a regular rhythm.
支持心脏和血液循环
左心室辅助装置 (也被称为 LVAD) — The left ventricle is the large, muscular chamber of the heart that pumps blood out to the body. When the left ventricle isn’t able to pump enough blood to the body on its own, LVAD可以帮助实现这一功能.
Implantable 卡ioverter Defibrillator
设备的作用
An ICD detects the rhythm of the heart and has wires which are implanted into the heart tissue which can deliver electrical shocks, 纠正心脏的节律, 根据需要.
设备使用原因
- Used in people at risk for recurrent, sustained ventricular tachycardia or ventricular fibrillation.
- 使心脏恢复正常节律.
- 有助于防止心源性猝死.
起搏器
A temporary 起搏器 may be needed in the hospital after a heart attack if you have a heart rhythm that is too slow. A 起搏器 may not be indicated long term unless damage to the heart's electrical conduction system from the heart attack will impact being able to have a normal heart rhythm and rate.
设备的作用
A small device that has wires which are implanted in the heart tissue to send electrical impulses that help the heart beat in a regular rhythm. 该设备由电池供电.
设备使用原因
When the heart's "natural 起搏器" is defective and causes the heart to beat too fast, 太慢或不规律, a 起搏器 helps the heart beat in a regular rhythm.

左心室辅助装置
The left ventricle is the large, muscular chamber of the heart that pumps blood out to the body. The LVAD is a battery-operated, mechanical pump-type device that's surgically implanted. It helps maintain the pumping ability of a heart when it can't effectively work on its own.
These devices are available in most heart transplant centers.
设备使用原因
This device is sometimes called a "bridge to transplant," but is also used in long-term therapy. People often must wait a long time before a suitable heart becomes available for transplant. 在此期间, the person's already-weakened heart may deteriorate and become unable to pump enough blood to sustain life. An LVAD can help the person while they are waiting for the heart transplant or even eliminate the need for the transplant. LVADs are also being used longer-term as ‘destination therapy’ in people with end-stage heart failure when heart transplantation is not an option.
设备的作用
The LVAD has a tube that pulls blood from the left ventricle into a pump. The pump then sends blood into the aorta (the large blood vessel leaving the left ventricle). The pump is placed at the bottom of the heart inside the chest. Another tube attached to the pump is brought out of the abdominal wall to the outside of the body and attached to the pump's battery and control system. LVADs are portable and are often used for weeks to months. People with LVADs can be discharged from the hospital and have an acceptable quality of life while waiting for a donor heart to become available.
