For single chamber pacing, either the right atrium (upper chamber) or the right ventricle (lower chamber) is paced. Only one pacing lead is used. For dual chamber pacing, both the right atrium and right ventricle are paced. This requires two pacing leads. Policy Pacemakers and defibrillators take over pacing your Why are there different types of pacemakers and different numbers of lead wires? A pacemaker is a medical device that generates electrical impulses delivered by electrodes to . There are three basic types of permanent pacemakers, classified according to the number of chambers involved and their basic operating.

The actual surgery typically lasts 30 to 90 minutes. Following surgery, the patient should exercise reasonable care with the wound as it heals.

There is a follow-up session during which the pacemaker is checked using a "programmer" that can communicate with the device and allows a health care professional to evaluate the system's integrity and determine the settings such as pacing voltage output.

The types of pacemakers should have the strength of his or her heart analyzed frequently with echocardiography, every 1 or 2 years, to make sure that placement of the right ventricular lead has types of pacemakers led to a weakening of the left ventricle.

The patient may want to consider some basic preparation before the surgery. The most basic preparation is that people who have body types of pacemakers on the chest may want to remove the types of pacemakers by clipping just prior to surgery or using a depilatory agent preoperative shaving has been on the decline since it can cause skin breakage and increase infection risk of any surgical procedure since the surgery will involve bandages and monitoring equipment to be affixed to the body.

Since a pacemaker uses batteries, the device itself will need replacement as the batteries lose power. Device replacement is usually a simpler procedure than the original insertion since it does not normally require leads to be implanted.

The typical replacement requires a surgery in which an incision is made to remove the existing device, the leads are removed from the existing device, the leads types of pacemakers attached to the new device, and the new device is inserted into the patient's types of pacemakers, replacing the previous device.

Periodic pacemaker checkups[ edit ] Two types of remote monitoring devices used by pacemaker patients Once the pacemaker is implanted, it is periodically checked to types of pacemakers the device is operational and performing appropriately.

Depending on the frequency set by the following physician, the device can be checked as often as is necessary.


Newer pacemaker models can also be interrogated remotely, with the patient transmitting their pacemaker data using an at-home types of pacemakers connected to their geographical cellular network.

This data can then be accessed by the technician through the device manufacturer's web portal. At the time of in-office follow-up, the device will be interrogated to perform diagnostic testing.

A test to measure lead integrity. The minimum amount of energy generally in hundredths of volts required in order types of pacemakers pace the atrium or ventricle connected to the lead.


The amount of time that the device requires at the preset amplitude to reliably pace the atrium or ventricle connected to the lead.

Types of Pacemakers

Estimated battery life at current rate: As modern pacemakers are "on-demand", meaning that they only pace when necessary, device longevity is affected by how much it is utilized.

Other types of pacemakers affecting device longevity include programmed output and algorithms features causing a higher level of current drain from the battery. An additional aspect of the in-office check types of pacemakers to examine any events that were stored since the last follow-up.

Your doctor will work with you to decide which type of pacemaker is best for you.

The surgery usually is done in a hospital or special heart treatment laboratory. Before the surgery, an intravenous IV line will be types of pacemakers into one of your veins.

You will receive medicine through the IV line to help you relax. The medicine also might make you sleepy. Your doctor will numb the area where he or she will put the pacemaker so you don't feel types of pacemakers pain.

Your doctor also may give you antibiotics to prevent infection. First, your doctor will insert a needle into a large vein, usually near types of pacemakers shoulder opposite your dominant hand. Your doctor will then use the needle to thread the pacemaker wires into the vein and to correctly place them in your heart.

An x-ray "movie" of the wires as they pass types of pacemakers your vein and into your heart will help your doctor place them. Once the wires are in place, your doctor will make a small cut into the skin of your chest or abdomen. He or she will slip the pacemaker's small metal box through the cut, place it just under your skin, and connect it to the wires that lead to your heart.

The box contains the pacemaker's battery and generator.
