What is Vvir pacemaker?

VVI or VVIR: VVI(R) is one of the more commonly used pacing modes. VVI(R) is ventricular demand pacing. The ventricle is paced, sensed, and the pulse generator inhibits pacing output in response to a sensed ventricular event.

Which conditions are indications for a patient to have a permanent pacemaker implanted?

The most common indications for permanent pacemaker implantation are sinus node dysfunction and high-grade atrioventricular block. In 2008, the American College of Cardiology (ACC), the AHA, and the Heart Rhythm Society (HRS) jointly published guidelines for pacemaker implantation.

What are the indications for pacemaker?

Sinus Node Dysfunction.

What are signs of pacemaker failure?

Signs and symptoms of pacemaker failure or malfunction include:

• Dizziness, lightheadedness.
• Fainting or loss of consciousness.
• Palpitations.
• Hard time breathing.
• Slow or fast heart rate, or a combination of both.
• Constant twitching of muscles in the chest or abdomen.
• Frequent hiccups.

What is Twiddler’s syndrome?

To the Editor: First described in 1968, pacemaker twiddler’s syndrome refers to permanent malfunction of a pacemaker due to the patient’s manipulation of the pulse generator.

What are the symptoms of a pacemaker insertion?

When the body does not receive enough blood, symptoms such as fatigue, dizziness, fainting, and/or chest pain may occur. Some examples of heart rate and rhythm problems for which a pacemaker might be inserted include: Bradycardia. This occurs when the sinus node causes the heart to beat too slowly.

Where is the pacemaker implanted in the heart?

The pacemaker is usually implanted in the chest, just below the collarbone. Your doctor may recommend this device to keep your heartbeat from slowing down to a dangerously low rate. The heart is a pump made up of muscle. The muscle is stimulated by electrical signals. These signals normally follow a specific circuit within the heart.

How is a pacemaker used to regulate the heart rate?

A pacemaker is a small electronic device that helps regulate a slow heartbeat. The pacemaker is usually implanted in the chest, just below the collarbone. Your doctor may recommend this device to keep your heartbeat from slowing down to a dangerously low rate. The heart is a pump made up of muscle.

Where is the sheath for a pacemaker insertion?

A local anesthetic will be injected into the skin of the chest at the insertion site. Once the area is numb, the healthcare provider will make a small cut (incision) at the insertion site. A sheath is put into a large blood vessel. The sheath is also called an introducer. It is usually put under the collarbone. The sheath is a small plastic tube.
