What is the difference between crt and pacemaker

It takes a few weeks to resume normal activities after implantation. Before leaving the hospital, consult your doctor about directions on wound care, taking a shower generally not recommended until a few days later , moving, driving, exercise intensity, places or appliances to avoid and going back to work.

Cardiac resynchronization therapy CRT is treatment to help your heart beat with the right rhythm. It uses a pacemaker to restore the normal timing pattern of the heartbeat. The CRT pacemaker coordinates how timing of the upper heart chambers atria and the lower heart chambers ventricles.

It also works on the timing between the left and right sides of the heart. This is called heart failure. Your doctor may find out that you also need an implantable cardioverter defibrillator ICD. This device helps fix serious heart rhythm problems. If you need this device, it may be combined with the CRT. CRT therapy means you will need to have the pacemaker placed under your skin by minor surgery.

Wires from the device are connected to the ventricles on both sides of your heart. The CRT device sends electrical signals to the ventricles to make them pump together the way they should. This type of electrical stimulation is called biventricular pacing. CRT therapy works in about 7 out of 10 cases of heart failure.

Not everyone with heart failure can be helped by CRT. For instance, if you have advanced heart failure, you are not as likely to respond to CRT.

Overall, CRT may improve your survival, heart function, and quality of life if you have mild to moderate heart failure. It also improves your ability to exercise. CRT is not considered a major or dangerous type of procedure. But like all surgery, it carries some risks. They include:. There may be other risks, depending on your specific medical condition.

Cardiac resynchronization therapy CRT devices help your heart beat more efficiently and monitor your condition so your doctor can provide the right treatment for you. Find out more about how your device works below. Cardiac resynchronization therapy CRT uses a device called a biventricular pacemaker also called a cardiac resynchronization device that sends electrical signals to both lower chambers of your heart ventricles.

The signals trigger your ventricles to contract in a more coordinated way, which improves the pumping of blood out of your heart. Sometimes the device also contains an implantable cardioverter-defibrillator ICD , which can deliver an electrical shock to reset your heartbeat if your heart rhythm becomes dangerously erratic. Cardiac resynchronization therapy is a treatment for heart failure in people whose ventricles don't contract in a coordinated fashion.

If you have heart failure, your heart muscle is weakened and may not be able to pump out enough blood to support your body. This can be worsened if your heart's chambers aren't in sync with each other. Cardiac resynchronization therapy may reduce your symptoms of heart failure and lower your risk of heart failure complications, including death.

All medical procedures come with some type of risk. The specific risks of cardiac resynchronization therapy depend on the type of implant and your overall health. Complications related to cardiac resynchronization therapy and the implantation procedure may include:. Cardiac resynchronization therapy requires a minor surgical procedure to implant a device in your chest. You'll likely be awake during the procedure, though the area where the pacemaker is implanted is numbed and you'll receive medication to help you relax conscious sedation.
