But there are also other things like certain medications and electrolyte disturbances that can cause a prolonged qt that can be corrected and is not in fact LQTS. I would stress to your cardiologist that your daughter be seen by an Electrophysiologist who is experienced in LQTS. Most doctors and even cardiologists are not qualified to properly diagnose LQTS. A prolonged QT for any reason needs to be treated, even a borderline one if she does have LQTS, with a Beta blocker at the very least.
Yesterday I had an EKG for an upcoming surgery. It came back stating Abnormal results, prolonged QT interval.... QTc >490ms. In my twenties I had 3 to 4 bouts of tachycardia, with a pulse of 190 or more. The hospital did an EKG and found nothing, and I have not had this expierence since ( I am a 47 year old female) My Dr has ordered another EKG for next week but I am wondering what this all means. The statements on the internet about sudden cardiac arrest scare me to death!
When a QT interval is prolonged due to the SSRI, the QT interval will speed up when the medication is withdrawn and removed from your body. For whatever reason, the med is slowing down conduction at the cellular level for certain people. It only happens when the drug is in your blood. This doesn't mean the person has LTQs.
I haven't read any studies that suggest consumption of SSRIs will result in LTQs.
A prolonged QT interval can cause symptoms similar to POTS but is far more dangerous and can cause a cardiac arrest if not treated properly. T wave abnormalities can also be related to a prolonged QT interval. But remember that what is written at the top of the ECG is not always true. It's only a computer interpretation but still needs to be read by a cardiologist and preferrably an Electrophysiologist (heart rhythm specialist).
Cardiologists are also famous for brushing aside a prolonged QT interval. It took me several months and different cardiologists before I found an Electrophysiologist and was diagnosed.
Funny T waves are also diagnostic for Long QT Syndrome and need to be examined further. There is a group online called SADS (sudden arrhythmia death syndrome) website is www.sads.org in the US and www.sads.ca in Canada. You can contact them if you need to find a specialist in your area.
Long QT Syndrome is normally a lifelong condition. That being said, a prolonged QT interval can be caused by medication or electrolyte abnormalities, even in healthy individuals without Long QT Syndrome. Additionally, some individuals with Long QT Syndrome don't have a consistently prolonged QT interval. It's possible to have a occasional normal EKG, and still have Long QT Syndrome.
I'm not sure if I am doing this correctly. I am trying to post this in the expert forum. I hope this works! Here is my question. I'm sorry it is sooo long!
My son was in the NICU the first few days of his life because he had a low heart rate (the lowest was 90). Although his heart rate stabilized in a few hours his EKG showed he had a prolonged qt interval. The cardiologist said it was caused by a medication I had been taking throughout my pregnancy.
I have had my Primary care physcian consult a cardiologist and preformed a holter and echo-both normal and they are not concerned about Long QT. My ER doctor was not concerned about Long QT as his assumption was that it was cause by low potassium.
I had even sent my EKGs to a arrythmia specialist at Mayo Clinic in Rochester to see if they thought I needed an appointment and they did not feel I needed an appointment given I have no family history of fainting or sudden death.
My son was in the NICU the first few days of his life because he had a low heart rate (the lowest was 90). Although his heart rate stabilized in a few hours his EKG showed he had a prolonged qt interval. The cardiologist said it was caused by a medication I had been taking throughout my pregnancy. At the hospital they did three EKGs. I just obtained his medical records today and im very confused.
t last long went to the emergency room to get checked out they did a EKG the doctor says that it looks good the result said inconclusive and also said borderline prolonged QT. Should i be worried or is possible that they are right o say it might just be that he can feel the extra beats. Would it be that painful for him. On a scale of 1 to 10 he says it's 11 when this occurs.
Yes, a prolonged QT-Interval could be an inherited condition and can lead to Arrhythmia. On the other hand, I had PVC's for many years and only now (I am 80 years old) do they occur at such short intervals that I personally (not a doctor) classified them as Arrhythmia and I have made an appointment with a cardiologist. But in your case he would have seen it on the ECG and told you.
The heart rhythm is perfect. 4 PACs is almost nothing, probably far less than average.
You should ask your doctor about the QT interval. Holter monitors are not reliable, the prolonged QT could be an error/artifact. I've never heard about QT changing that much in just a couple of hours.
I understand you to say "EKG" baseline... I do typos myself, just read some of my other posts if you can : ) Well, to your question: I also understand your doctor knows your health history, thus the EKG, and believes the medication is safe. It is my guess that the "prolonged QT" is just a possibility and passes when the medication is stopped.
Anyway I saw cardiologist along with my ECGS and he said two of them had prolonged qt the range was 472/551ms. The other ECGS were in normal limits as far as the QT is concerned. He is not too worried. I had a holter monitor which showed nothing but PVCs (around 100). He is going to send me off to a rhythm specialist. My cardiologist asked me if my family members have long QT syndrome or a history of sudden cardiac death.
If your QT was 448 msec and your QTc was 488 msec, your heart rate was 71 (and the anxiety was obviously not that bad).
I didn't know anxiety could prolong the QT interval (in my case it shortens it) at my EKG with high anxiety and fairly low heart rate (which is uploaded on my profile) my QT was 330 msec and QTc 358 msec, but I guess people are different. A slightly long QT doesn't mean you have LQTS, which is often seen on EKG as specific changes in addition to the prolonged QT.
