COVID-19 vaccine may have added side effects in subjects with known heart disease.

I was 67 years old when I received my 2nd Moderna vaccination. Prior to the vaccination I had a history of abnormal ECGs in the last 30 or more years. They showed at different times, athletic heart, low level RBB. abnormal changes, possible enlarged left atrium. The eckocardiograms where always normal. I got the 2nd vaccine on 03/12/21. On 03/29/21 my ECG showed a LBBB type 1. The echocardiogram was normal again. I started to experience symptoms during April and May. Early june I fainted. went to ER the next day. ECG showed AV block level 1 and a few minutes later complete AV Heart block. I had a pacemaker implanted on 06/03/21.

Is it possible that the vaccine contributed to my needing a pacemaker?

Take a look at the articles bellow:

Conclusion: COVID-19 vaccine may have added side effects in subjects with known heart disease. Humoral response towards the vaccine might interfere with the conduction system of the heart and more so in patients with diseased and scarred myocardium.

The vaccine I was given was Moderna. And I recently reported this to the CDC.



Possible effects of the covid vaccine

by AgentX86 - 2022-02-28 15:50:56

Absolutely they could be connected but you're unlikely to get anyone to admit it. There are many reports of heart problems caused by the covid vaccine but few statistics, at least publicly available.  Like many issues today, information that doesn't fit a specific narrative is surpressed. "Follow the science", you know. 

No, I'm certainly not an anti-vaxer, just anti-gaslighter.

As AgentX86 said, definintely COULD be related, but no real way to find out until enough time and research has passed.

I noticed that when I got COVID this past December, my vision/motion spells (that I have had since the PM implant) were mostly the same, only now they would be accompanied by a ringing in my ears. Sometimes (not always), I will hear a ringing in my ear and then a vision/motion spell would follow shortly or begin immediately. The ringing would also happen like clockwork if I laid on my right side while sleeping.

I brought this up to my general doctor, my neurologist and my cardiologist and they all basically said "unsure about it being related to COVID, interesting that it is happening though..."

Hope you continue to focus on getting better and recovering! If COVID did play a key role in this, then there's not really much you or any of us can do aside from accept it and do our best not to get it again.

Take care


"The echocardiograms were always normal"

Good to meet you, Biker, and I hope you're feeling well.  My only Q is - were these stress echos?  My RBBB was latent until it wasn't.  I was about a decade younger than you when it decided to go full bore. It took a stress echo to identify it - the stationary echo showed all ok.  This was just my experience and I'm not medically trained, but my timeline of progression of symptoms was very similar to yours, though it transpired years before COVID and associated vaccines were around.  I spent a lot of time and energy wondering why and finally got to the point of realizing the most productive way for me to go forward was to accept that it is what it is.  If you're interested in providing info for medical research, no doubt there are research organizations which will take your data.  Best wishes to you.

You didn't say, but I'll assume you got one of the mRNA vaccines. If you understand how the mRNA vaccines work (i.e., simply uses the robosomes in your cells to make antibody proteins), it is hard to imagine that the vaccine has anything to do with your heart situation. It's the old adage: "The rooster crowed, and then the sun came up; so I guess the roster is the one who makes the sun come up." It's called a coincidence <grin>. 

Allow me to ask you this.....I got a vaciine yesterday; today I slipped on ice and broke my leg. Did the vaccine have anything to do with me slipping? I've never slipped before.

P.S. Allegic reactions to anything injected into you blood stream are an entirely different matter. Some folks are allergic to various ingredients found in vaccines (that's why they make you wait for 15 minutes). An allergic reaction could certainly set off someting.


by AgentX86 - 2022-02-28 22:22:28

It seems there are a lot of things we didn't know about mRNA and a lot more that we still don't. We are finding out a lot more than we knew when it was approved.

Something we do know:

Question nothing at your peril

You only prove my point. We have been told so many lies, nothing is surprising.



Nothing is surprising, including the number of people who no longer trust what they're told and no discussion or questioning (scientific or otherwise) is allowed, so will not take the vaccine.  This is exactly what you're doing. Instead of challenging the facts, you shoot the messenger.  Good going Mark Z.


How many noughts in a billion ?

by IAN MC - 2022-03-01 06:27:21

Biker asks the question  " Is it possible that the vaccine contributed to my needing a pacemaker? ".

Although I'm a great believer in " Never say Never"  I think a cause-and-effect between Covid vaccination and needing a pacemaker is incredibly unlikely .

Over 10.7 BILLION Covid vaccinations have now been given worldwide .The number with pre-existing heart conditions would be huge . If this mind-blowing number of jabs had resulted in  an increase in pacemaker sales, we would have  known about it.

An increasing clinical need for pacemakers would have led to a hike in PM implants  . This would have been evident to manufacturers  (as well as to  bulk-buyers ). These usage trends would have been made public  IMHO.


mRNA Vaccines

May I just remind everyone to try to keep this thread respectful.  That is the only way we can ever hope to move this important discussion forward “positively” so that we may all benefit, whatever our views.

Biker97, looking at your post, it would appear that some cardiac abnormalities were clearly seen over many years, well before your total block appeared, although I appreciate your valid concerns immediately following your Covid vaccine.  Unfortunately once electrical disturbances start, they usually progress.  Being an athlete can also be a risk factor for changes in heart function/ECG abnormalities although clearly the benefits of exercise are well known and encouraged.

You ask, is it possible that the vaccine contributed to your needing a pacemaker? Yes, it is possible but it is also possible that you would have developed AV block in any case because of your past history and lifestyle. You have the treatment now for your condition and I hope you will benefit from your pacemaker and go on to live a quality life, free from the fear of worsening symptoms in the future.

Thank you for bringing these links to our attention.  I hope you get some helpful answers.

Living with "Don't know"

Here's a fact about rhythm disorders. Over time they tend to get worse, and they don't tend to go away or get better.

Since we know your heart's electrical problems were most likely going to get worse anyway, the unknown is when they were going to get worse. Since we can't know when it was going to happen, we cannot say if anything that happened made it get worse sooner.

Read some of the posts here. You'll see that the exact moment when you need a pacemaker is not always a black and white. I had no heart disease. I was functioning and my EKG was NORMAL. I know now I'd probably had a slow heartrate and pauses intermittantly for a couple of years. The need for a pacemaker only became clear when the bradycardia and pauses became bad enough.

Who knows how long you could have used a pacemaker before it became clear that you could no longer get along without one?

By the way, 10 years post-pacemaker, my EKG is no longer normal, and I have lots of arrythmias I didn't used to have. Like you, by tiny degrees, a little here a little there, my condition was getting worse before the shot.

Then I took the shot, had hernia repair surgery, took a trip to Florida, and watched more TV than I ever have before. All had risks, known and unknown associated with them. All of them also had some benefits. Which one shall we say caused my condition to get worse? Or shall we admit that my condition would have gotten worse no matter what I did, or didn't do.

I don't know. I don't see how knowing would change my situation in the slightest.

Everybody likes knowing better than not-knowing. Everybody wants the solid feeling of being really sure. But sometimes the answers just aren't there. That's reality.

Sometimes, I don't know is the best, truest answer there is.

Covid vaccination and the heart

by Selwyn - 2022-03-02 14:19:57

Hi Biker97

I posted on this subject 30th July 2021 (please see).

The chicken and the egg discussion continue (which I also hope for is a discussion and not an argument).

For a balanced review see:

Having had an arrhythmia for a month after Covid infection, I am more than happy to receive my 4th Covid vaccination tomorrow morning. 



Covid vaccine

by AgentX86 - 2022-03-02 16:22:03

Note that I never said that vaccines were bad, only that it's not without risk, as we've been told. We now know that it's not perfect, as we were told, either. I encourage everyone to think for themselves and don't believe what you're told, specifically on social media or the mainstream media. Everything we've been told has been filtered with a single mind.

Listen to those who have been filtered, and think for yourself. Thats what science is about. There is nothing to be learned from parrots. This isn't just applicable to covid.

You know you're wired when...

The meaning of personal computer is taken a step further.
