I'm just wondering, if you have a cardiac pacemaker, can you have a heart attack or go into cardiac arrest?

I'm just wondering, if you have a cardiac pacemaker, can you have a heart attack or go into cardiac arrest?

Yes: The pacemaker will keep functioning with electrical stimuli when the detected pulse is below set rate.
Heart attack- muscle death can happen. If it happens at site of pacer contact to heart, the pacer can fail to stimulate. ...Read more

Myocardial Infarction (Definition)

Myocardial Infarction means some of the heart muscle dies because of insufficient oxygen supply. Most often this occurs because the coronary artery is blocked by plaque & clot. Other causes include tears in the artery wall, extremely high oxygen demand (eg, rapid arrhythmia, heart valve disorder, or severe systemic illness.) Prompt treatment can minimize heart damage & ...Read more

If you have a pacemaker, can you still have a heart attack / cardiac arrest?

If you have a pacemaker, can you still have a heart attack / cardiac arrest?

Yes: Pacemaker helps to control or regulate the rhythm (electricity) of the heart. Heart attack is related to blockages of the arteries of the heart (plumbing, if you want the analogy). Pacemaker will prevent the heart beating too slow but will NOT prevent blockages from developing or producing heart attacks ...Read more

Can you still have a heart attack or go into cardiac arrest if you have a pacemaker?

Can you still have a heart attack or go into cardiac arrest if you have a pacemaker?

Yes: Both of these problems are due to issues not addressed by the pacemaker. A heart attack is generally due to a blockage and a heart artery, and cardiac arrest is usually due to an exceedingly fast heart rate where the pacemaker only fixes slow heart rates. A defibrillator is the device of choice to treat cardiac arrest. ...Read more

Help please? How is a pacemaker affected during a heart attack?

Help please? How is a pacemaker affected during a heart attack?

Pacer: A heart attack usually doesn't affect an electronic pacemaker. The device will help prevent the heart from slowing excessively and usually won't be affected by rapid heart action. If a cardiac arrest occurs and defibrillation is necessary, the electric shock could possibly affect the pacer circuitry. ...Read more

Can you tell me how is a pacemaker affected during a heart attack?

Can you tell me how is a pacemaker affected during a heart attack?

Pacer/MI: The pacemaker electronics will not be affected by a heart attack. The muscle damage in the heart could change threshholds for sensing and pacing and cause problems with those. Abnormal rhythms associated with the heart attack might also affect what the pacemaker does. ...Read more

My husband, 47 years old, suffered a heart attack 2 years ago. He has 2 stents & now a pacemaker. What are the cons of a pacemaker?

My husband, 47 years old, suffered a heart attack 2 years ago. He has 2 stents & now a pacemaker. What are the cons of a pacemaker?

Very few: The indications are for slow heart rate which can be dangerous- even lethal.
There are risks of implantation, but those are past.
Some wire or battery failures over time.
Rare perforation, infection, clots.

Overall very necessary and very safe. ...Read more

Dad had a massive heart attack 6 months ago. His heart working at 29% they said he needs a pacemaker. An he won't have it done he thinks he's fine??

Dad had a massive heart attack 6 months ago. His heart working at 29% they said he needs a pacemaker. An he won't have it done he thinks he's fine??

He probably was told: That he needs a defibrillator not a pacemaker. A weakened heart muscle places him at significant risk for sudden cardiac death. He could feel just fine...until he dies! A defibrillator would prevent this sudden unexpected terminal event. He should be encouraged to discuss this more openly with his health care professionals. ...Read more

Hi, I had a heart attack on March 6, 2016. My cardiologue quickly jumped to the conclusion that I needed a pacemaker. I do not have low heartbeat.?

Hi, I had a heart attack on March 6, 2016. My cardiologue quickly jumped to the conclusion that I needed a pacemaker. I do not have low heartbeat.?

No: Most patients with heart attacks do not need pacemakers.
Pacemakers are only needed for patients whose heart rate is too slow or for whose electrical system does not conduct signals reliably from the top chambers to the bottom chambers of the heart. ...Read more

Pacemaker problem regarding heart attack/cardiac arrest, can you tell me about this?

Pacemaker problem regarding heart attack/cardiac arrest, can you tell me about this?

Unrelated: There is far less than a 1% risk of heart attack during pacemaker implantation. Once it is implanted, there is almost no way it could cause a significant heart attack. It will not prevent most cardiac arrests. An ICD can treat cardiac arrest from ventricular tachycardia or fibrillation ...Read more

My grandma has been on enalapril for 25 years since a heart attack went into hospital for pacemaker and they told her to stop she has now passed away?

My grandma has been on enalapril for 25 years since a heart attack went into hospital for pacemaker and they told her to stop she has now passed away?

Many possibilities: It is very hard to say why your grandmother passed away from the short question. But regarding enalapril, abrupt withdrawal can be associated with hypertension that is difficult to manage and possibly with increased risk of new cardiac events or heart failure. However, with holding the medication before surgery is commonly done, but remains controversial. Other causes should be considered too. ...Read more

What to do if I had a major heart attack and I am 44 years old I have to have a pace maker and a defibrillator put in?

What to do if I had a major heart attack and I am 44 years old I have to have a pace maker and a defibrillator put in?

MI, ICD: With your combination of problems, you should have received instruction about your status and diet, exercise, not smoking, lots of medications and how to maximize your chances of length and quality of life. Look at this site and read as much as possible:

Resting heart rate as a young man was 50-55. Doctors are considering a pace maker 2 years post heart attack?

Resting heart rate as a young man was 50-55. Doctors are considering a pace maker 2 years post heart attack?

Ok: Your youth and cardiovascular conditioning are of historic interest.
If you now have symptomatic slow pulse= bradycardia, syncope, heart failure etc. One may benefit from pacing.
After a heart attack the electrical system of the heart can be damaged and one benefits from proper atrioventricular pacing or even dual pacing for chf. ...Read more

Could you have a heart attack in your sleep?

Yes: You need to block the artery to have a heart attack. This can occur at any time of the day or night, awake or asleep. ...Read more

Could you have a heart attack from too much stress?

Yes: Stress can increase the demand for blood flow to the heart. If the coronary arteries have blockages, then they may not be able to supply enough blood to the heart muscle and a heart attack can occur. Takotsubo cardiomyopathy or "broken heart syndrome" can also be caused by stress. This condition causes the heart to enlarge and pump poorly. ...Read more

Can you have a heart attack and your arteries and heart okay?

Can you have a heart attack and your arteries and heart okay?

It's possible: In most cases, the arteries are damaged if a patient has a heart attack, but that does not always mean a patient needs a stent or there is heart damage. However, these patients still need aggressive medical treatment w aspirin, statin, blood pressure meds, and maybe plavix (clopidogrel). ...Read more

What life expectancey if you have a heart attack 3 months after a 4 x CABG and then another the next week. Can this be terminal?

Hard to say: But obviously there is a high risk for more heart damage, not to mention the worsening quality of life. Consider a strict plant based diet (I.e. The book "prevent and reverse heart disease") as at this stage the patient is typically on max medical therapy. ...Read more

Pacemaker (Definition)

A pacemaker is a device which sends electrical signals to the heart triggering heartbeats when needed. There are many ways to implant and configure a pacemaker; it may beat the top chambers (atria), lower chambers (ventricles) or both. Some systems stimulate both the left and right ventricles together. Pacemakers generally treat abnormally slow heart rhythms and certain ...Read more

Heart Attack (Definition)

A life-threatening condition in which the blood vessels that supply the heart becomes occluded and thus the heart itself is not longer receiving any blood flow. Without this blood flow, the heart muscle dies and cannot pump blood to the ...Read more
