I'm on methadone, I have prolonged qt interval, so have to come off. I've heard the tapering off is so difficult, true?

not impossible : You certainly don't want to remain on Methadone if you have prolonged qt. Risk of sudden cardiac death is real, especially at higher doses. If tapering becomes intolerable, work with an addiction specialist to help you through the process and possibly transition you to another safer agonist based replacement therapy. ...Read more

I suffer from chronic hyperventilation at times. I read that this can cuase hypocalcemia and prolonged qt interval. Is this true? Is it dangerous?

Mildly: Hyperventilate, and you'll drop your ionized calcium (it's your body adjusting to keep you healthy) and change your ekg. The only danger to life is if you already have something badly wrong such as coronary artery atherosclerosis, or if you get worked up with invasive testing by an overzealous physician. Hope you're able to get the hyperventilation under control -- be brave & good luck. ...Read more

An EKG showed a prolonged QT interval and it typed that I may be low in calcium. Blood work came back fine. He didn't seemed concerned, should I be?

An EKG showed a prolonged QT interval and it typed that I may be low in calcium. Blood work came back fine. He didn't seemed concerned, should I be?

Ask some questions.: A lot of EKG machines do automatic interpretations. I think they over read and report issues that aren't there or aren't significant. Prolonged QT can be a clinically significant finding but there are some ifs. It can be seen if you are on certain medications. It is a normal finding in certain percentage of the population. Clearly, you are concerned. Call your doctor and ask for clarification ...Read more

My friend had an EKG done and his qt/qtc was 475/400. Does this mean he has prolonged qt interval? He's on seroquel (quetiapine)

My friend had an EKG done and his qt/qtc was 475/400. Does this mean he has prolonged qt interval? He's on seroquel (quetiapine)

Lots of drugs do : The qtc interval is prolonged by multiple commonly used drugs, and seroquel (quetiapine) is but one. The duration is not severe, and likely appropriate at this point, but certainly on the high normal side. Maybe need to monitor, but typically these items do not cause symptoms unless too many drugs affect the a/v nodal conduction. ...Read more
