Resynchronization Devices

What are the potential benifits of Cardiac Resynchronization therapy (CRT)

According to clinical trial results with selected patients, cardiac resynchronization therapy:     * Increased the amount of daily activities patients could perform without experiencing the symptoms of heart failure     * Extended the exercise capacity of patients with HF, as measured by the distance they could walk in 6 minutes     * Improved the overall quality of life     * Promoted changes in the anatomy of the heart that improved cardiac function     * Reduced the number of days patients spent in the hospital, and the total number of hospitalizations

How Does CRT Work?

In the normal heart, the electrical conduction system delivers electrical impulses to the left ventricle in a highly organized pattern of contractions that pump blood out of the ventricle very efficiently. In some patients with systolic heart failure caused by dilated cardiomyopathy (an enlarged heart) this electrical coordination is lost. Uncoordinated heart muscle function leads to inefficient ejection of blood from the ventricles. CRT devices pace both the left and right ventricles simultaneously to resynchronize the muscle contraction and improve the efficiency of the weakened heart.

Will a cellular phone interfere with my device?

You can use a cellular phone with most implantable devices. Ask your doctor about using a cellular phone.

Are there any dietary restrictions?

There are no dietary restrictions associated with your device. There may be dietary restrictions, however, associated with your heart condition. Be sure to follow your doctor’s advice with regard to sodium, fats and sugars, and other dietary factors.

Will I be able to hear or feel my CRT device?

You will not be able to hear your device. It will not make any noise. Secondly, you may be aware of your pacemaker or ICD initially, but, over time, this sensation will lessen.

Will I be limited in my activities now that I have a CRT device?

Typically, you will be able to continue to engage in activities that you participated in before device implantation. You may find that you actually have more energy than before, because the CRT may help to lessen the symptoms associated with heart failure. Your doctor is your best source of information, though, regarding specific activities. Consult with him or her before participating in something new or strenuous.

How long will my CRT device last?

On average, CRT-Ps last seven years and CRT-Ds last five years. How long a device lasts, however, depends upon how much energy is required to pace the heart. Thanks to ongoing research and development, device life continues to increase as size decreases, making these devices more comfortable.

What is it a heart failure device?

Heart failure is just like a implanted defibrillator or pacemaker with capabilities of resynchronization.

How is heart failure treated?

Treatments for heart failure include lifestyle changes, medications, surgeries, and cardiac resynchronization therapy.

How is heart failure diagnosed?

In addition to a physical exam, your doctor may use blood tests, x-rays, an ECG test, an echocardiogram, or other tests to diagnose heart failure.

What are the symptoms of heart failure?

Symptoms include fatigue, shortness of breath with or without exercise, wheezing, or a dry hacking cough after lying down.

What are the causes and risk factors of heart failure?

The causes of heart failure vary with age and family history. Some risk factors include coronary artery disease, high blood pressure, and valvular disease.

What is heart failure?

Heart failure is a progressive condition in which the heart muscle has been damaged by disease or injury and it cannot pump enough blood and oxygen to meet the body”s needs.
