My 18 yr old son developed SVT with a heart rate of about 180 in the Army 2 weeks after the Jab- Absolutely no family history from either side. He called me and was scared to death. I tried to have him use vagal maneuvers to no avail so then I told him to go to the ER. He got 1 dose of Andenosine IV which converted him To SR.. No problems since. Any irritation around the heart muscle can cause an arrhythmia. SA node (atrial) less serious than an AV node (Ventricle) interruption. Best of Luck Brother
Sorry to hear your son had Sx.....but, thankfully easily fixed in his case.
Here is a study of
48 Million people....
"The study used data collected anonymously from 48 million people – nearly every adult in England and Wales – in Great Britain's National Health System from January 2020 until the day before COVID-19 vaccines were made available that December.
The findings reinforce the message that for people who have cardiovascular conditions, "taking established preventative medications and managing your risk factors is even more important now than it was before the pandemic," said Jonathan Sterne, the study's senior author and a professor of medical statistics and epidemiology at England's University of Bristol.
The study looked at results from 1.4 million diagnoses of COVID-19, which researchers said led to an estimated 10,500 additional cases of clot-related problems.
Extensive data collection and linkage in effect across Great Britain enabled researchers to crunch the numbers, Sterne said.
Researchers found that the first week after a COVID-19 diagnosis, the risk of an arterial blood clot – the kind that could cause a heart attack or ischemic stroke by blocking blood flow to the heart or brain – was nearly 22 times higher than in someone without COVID-19. That risk dropped sharply, to less than four times higher, in the second week.
"Between 27 and 49 weeks, there is an approximately 30% increased risk for arterial clots, Sterne said. "But the elevation is greater for longer" for clots in veins, which include deep vein thrombosis and pulmonary embolism, when a clot travels to the lungs.
In the first week after a COVID-19 diagnosis, the risk of such venous problems was 33 times higher. By the third and fourth weeks after diagnosis, the risk was still about eight times higher. And between 27 and 49 weeks later, the risk was still 1.8 times higher than in somebody who had never had COVID-19.
"I do think that that is a new element to the story – that the risk is not only around the time of the acute COVID infection," said Dr. Karen Furie, chief of neurology at Rhode Island Hospital and chair of neurology at Brown University's Warren Alpert Medical School in Providence. The higher risk of clots in veins than in arteries also got her attention. Furie was not involved in the study.
Elevated risks persisted no matter whether someone was hospitalized for COVID-19, although risks were greater in people who were hospitalized. The study also showed that clot risks were higher in Black and Asian people.
Overall, however, clots were rare. The overall increase in risk of developing an arterial clot in the 49 weeks after a COVID-19 diagnosis was 0.5%. For a venous clot, the risk was 0.25%. After 1.4 million COVID-19 diagnoses, that corresponds to about 7,200 additional heart attacks or strokes, and 3,500 additional cases of pulmonary embolism, deep vein thrombosis or other venous problems.
Furie said the size of the study made it "extremely powerful." But the authors acknowledged they might have missed some cases of COVID-19 before testing became widely available, or vascular events if people avoided hospitals early in the pandemic"
