These specialized heart experts often use a commercially-available therapy called CRT, for cardiac resynchronization therapy, which can be delivered through a surgically implanted defibrillator or pacemaker. And a new study shows it can significantly improve outcomes for cancer patients with weakened hearts.
What are the benefits of having a pacemaker?
Having a pacemaker should improve symptoms caused by a slow heartbeat such as fatigue, lightheadedness and fainting. Because most of today's pacemakers automatically adjust the heart rate to match the level of physical activity, they may can allow you to resume a more active lifestyle. Your doctor should check your pacemaker every 3 to 6 months.
How does an implantable pacemaker work?
An implantable pacemaker relieves symptoms of a slow, irregular heart rhythm. It does this by restoring normal heart rates. A normal heart rate provides your body with the proper amount of blood circulation.
What happens if you have radiotherapy with a pacemaker?
The radiation can cause chemical changes in the structure of the pacemaker and electrical energy disturbances during the treatment. It depends on the type and model of your pacemaker and the dose of radiotherapy you are going to have.
Can a nurse monitor a pacemaker during treatment?
But a nurse or trained radiographer (sometimes called a radiotherapist) might monitor the pacemaker before, during and after treatment if your pacemaker is directly in the radiotherapy field. This is most likely to be for people who have cancer of the lung or breast.
Can pacemaker prolong dying process?
Pacemakers are not resuscitative devices, and they will not keep a dying patient alive. Most dying patients become acidotic before cardiac arrest, which effectively renders a pacemaker nonfunctional, as under such conditions, the myocardium does not respond to the pacemaker's discharges.
Can you have chemo with a pacemaker?
Pacemaker-like device improves heart function in patients with chemotherapy-induced cardiomyopathy. With the advent of new therapies, cancer patients are surviving longer than ever before -- but the incidence of side-effect chemotherapy-induced cardiomyopathy (CHIC), or weakness of the heart muscle, is increasing.
How does death work with a pacemaker?
A pacemaker does not actually beat for the heart, but delivers en- ergy to stimulate the heart muscle to beat. Once someone stops breathing, his body can no longer get oxygen and the heart muscle will die and stop beating, even with a pacemaker.
Do you feel better after a pacemaker?
Having a pacemaker can help you be more active. It may also help you stay out of hospital and live longer. Above all, you should feel better. Previous symptoms, such as breathlessness or dizziness, should disappear.
How can I protect my heart during chemo?

Can a pacemaker be controlled remotely?
Some types of pacemaker can be controlled remotely by a specialist from your heart (cardiology) team during the treatment. When you finish your radiotherapy, your heart specialist will continue to keep a close eye on you.
What is a pacemaker?
The pacemaker consists of a pulse generator, which contains the battery and programming circuitry, and one to three leads, which provide access to the chamber of the heart being paced (right atrium, right ventricle, or coronary sinus for left ventricle pacing). Contemporary pacemakers have numerous programmable features that can be changed to optimize function. The pacing mode selected depends on the underlying rhythm disturbance, associated medical problems, and exercise capacity.
What is the most common indication for pacemaker therapy?
Sinus node disease is the most common indication for pacemaker therapy. This includes sinus bradycardia, sinus arrest, sinus pauses, chronotropic incompetence (inability of the sinus node to accelerate), or tachy-brady syndrome, which refers to alternating periods of tachycardia (often atrial fibrillation with rapid ventricular response) and then bradycardia (often prolonged sinus pause after termination of the atrial tachyarrhythmia). Most cases are due to idiopathic degeneration and fibrosis of the sinus node although it can also be due to medication, hypothyroidism, advanced liver disease, hypothermia, amyloidosis, elevated vagal tone, hypoxia, and hypercapnia. Sick sinus syndrome is the combination of symptoms (pre-syncope, syncope, decompensated heart failure) and sinus bradycardia or sinus pauses.
Why is evidence based care important?
It is important to incorporate evidence based care into clinical practice so that patients with sinus node dysfunction and atrioventricular conduction abnormalities who would benefit from permanent pacemaker implantation can be identified. The general practitioner is commonly involved in the evaluation of patients with presyncope and syncope. Clinical history and the 12 lead electrocardiogram are central in the initial evaluation to identify patients with potential cardiac etiologies, including bradyarrhythmias, who are at increased risk of mortality. Clinicians should be familiar with the current guidelines for pacemaker therapy so these patients can be appropriately referred to cardiology. It is also important to understand what elements from the history are important in the evaluation of patients with a pacemaker as well as some of the common issues encountered by patients with these devices in the hospital.
Why do you need a pacemaker?
A pacemaker is a small device that's placed under the skin in your chest to help control your heartbeat. It's used to help your heart beat more regularly if you have an irregular heartbeat (arrhythmia), particularly a slow one. Implanting a pacemaker in your chest requires a surgical procedure.
What is an implanted pacemaker?
An implanted electronic pacemaker mimics the action of your natural electrical system. A pacemaker comprises two parts: Pulse generator. This small metal container houses a battery and the electrical circuitry that regulates the rate of electrical pulses sent to your heart. Leads (electrodes).
How many wires are in a pacemaker?
Depending on your condition, you may have a pacemaker with one to three flexible, insulated wires (leads) placed in a chamber, or chambers, of your heart. These wires deliver the electrical pulses to adjust your heart rate. Pacemakers are implanted to help control your heartbeat. They can be implanted temporarily to treat a slow heartbeat ...
What is a biventricular pacemaker?
Biventricular pacemaker. Biventricular pacing, also called cardiac resynchronization therapy, is for people with heart failure with abnormal electrical systems. This type of pacemaker stimulates the lower chambers of the heart (the right and left ventricles) to make the heart beat more efficiently.
How far away from pacemaker should I keep my phone?

You'll likely be awake during the surgery to implant the pacemaker, which typically takes a few hours. You'll have an intravenous line placed, through which you might receive medication to help you relax.
Which type of pacemaker carries electrical impulses to the right ventricle?
Single chamber pacemaker. This type usually carries electrical impulses to the right ventricle of your heart. Dual chamber pacemaker. This type carries electrical impulses to the right ventricle and the right atrium of your heart to help control the timing of contractions between the two chambers. Biventricular pacemaker.
hmmm
I've never heard that we can't have any traditional cancer treatments! MRI's are out of the question so that makes diagnosing a bit more challenging, but I've never heard that radiation or chemo were a problem.

Radiation effect on pacer
Smitty's post is right on. Radiation deteriorates semiconductor components in electronic circuits and it is dose dependent.
BillMFl
My brand new Medtronic pm came with a very informative booklet. It said that radiation treatments that could be carefully focused so as not to radiate the pm were ok. Cyber knife is just one example and there are other types of focused beam radiation.. Suggest that you get a second opinion.
How do pacemakers work?
What is a pacemaker? 1 The generator is a small battery-powered unit. 2 It produces the electrical impulses that stimulate your heart to beat. 3 The generator may be implanted under your skin through a small incision. 4 The generator is connected to your heart through tiny wires that are implanted at the same time. 5 The impulses flow through these leads to your heart and are timed to flow at regular intervals just as impulses from your heart's natural pacemaker would. 6 Some pacemakers are external and temporary, not surgically implanted.
Is a pacemaker surgically implanted?
The impulses flow through these leads to your heart and are timed to flow at regular intervals just as impulses from your heart's natural pacemaker would. Some pacemakers are external and temporary, not surgically implanted. View an animation of a pacemaker.
What is an implantable pacemaker?
An implantable pacemaker relieves symptoms of a slow, irregular heart rhythm. It does this by restoring normal heart rates. A normal heart rate provides your body with the proper amount of blood circulation.
What are the risks of a pacemaker implant?
Risks associated with pacemaker system implant include, but are not limited to, infection at the surgical site and/or sensitivity to the device material, failure to deliver therapy when it is needed, or receiving extra therapy when it is not needed.
Does a pacemaker help with bradycardia?
By regulating the heart’s rhythm, a pacemaker can often eliminate the symptoms of bradycardia. This means individuals often have more energy and less shortness of breath. However, a pacemaker is not a cure. It will not prevent or stop heart disease, nor will it prevent heart attacks.
How many people have cardiac pacemakers?
Background Worldwide more than 3 million people have cardiac pacemakers. Over 600,000 new pacemakers are implanted each year, with most of these devices in patients over the age of 60. Although pacemakers were once primarily used to treat bradyarrhythmias (e.g. heart block), more recently, patients with subvalvular stenosis, and atrial fibrillation may qualify for pacemakers. Additionally, patients with congestive heart failure may receive biventricular pacemakers or cardiac resynchronization therapy devices (CRT) to improve symptoms. This Fast Fact discusses management of cardiac pacemakers at life’s end. Fast Fact #112 discusses implantable cardioverter-defibrillators.
Does downgrading affect pacing?
Downgrading does not affect the symptomatic benefits of pacing. ·While a trained radiologist or cardiologist may be able to discern the thicker RV lead and the visible coil of a CRT-D device on a chest x-ray, clinical distinction between CRT-D and CRT-P is best achieved by interrogating the device.
Can a pacemaker cause death?
In contrast to popular belief, it is rare that disabling the pacemaker will result in a swift and painless death as few patients are 100% pacemaker dependant, particularly during the period of imminent death (Fast Fact # 3), where tachycardia is the most common rhythm.
Can a pacemaker keep you alive?
However, a pacemaker is not a resuscitative device. In general, pacemakers do not keep dying patients alive, as terminal events are often due to sepsis, hemorrhage, pulmonary emboli, or arrhythmias from metabolic abnormalities associated with end-stage cancer, liver, or renal failure. At the time of death, the myocardium is usually too sick ...
