What are CRT devices?

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).

What is the difference between an ICD and a CRT-D?

When patients have a life-threatening arrhythmia, the ICD delivers an electrical shock to help restore a regular heartbeat. A CRT-D differs from an ICD in that it has a second electrode over the left ventricle of the heart to help synchronize a patient’s heartbeat and improve cardiac function.

How does the CRT work?

A CRT works by moving an electron beam back and forth across the back of the screen. Each time the beam makes a pass across the screen, it lights up phosphor dots on the inside of the glass tube, thereby illuminating the active portions of the screen.

What are basic pacemaker precautions?

Certain activities may need to be avoided for a period of time after the pacemaker surgery, and the device should be checked regularly to make sure it is working properly and has adequate battery life. Other precautions include avoiding MRIs and certain other types of machinery,…

What’s the difference between an ICD and a CRT-D?

An ICD can have one or two wires, called leads, depending on what your heart needs. One lead goes in the right ventricle, and if you need a second lead, it will be placed in the right atrium. A CRT-D system adds a third, attaching a lead to the left ventricle so it can help both sides beat in synch…
