Blood glucose qt interval

Common Questions and Answers about Blood glucose qt interval


Avatar n tn I am 33 am TRYNA SEE IF my ventricular rate is 86 atria rate 86 qrs interval is 74 qt interval is 374 qtc is 447 p axis is 30 R axis is 21 t axis is 21 now is all this normal are should I be alarm
Avatar f tn m not a physician) is that Zoloft may prolong QT interval. I think uncorrected QT of 448 msec is slightly long at heart rate 71. I would recommend that you ask a cardiologist and preferrably bring the EKG. Do not stop taking Zoloft without talking to your doctor.
Avatar m tn Everyone have their unique relationship between heart rate and QT interval. People with SQTS (Short QT syndrome) have a fixed QT interval, say, 260 msec regardless of heart rate. If such a person had a heart rate of 200, the formula would show a long QT interval. Which clearly is wrong. My QT interval is somewhat less rate-dependent than what is normal. It really doesn't matter.
Avatar n tn Yes, a well known side effect of the majority of SSRI''s is that they can prolong the QT interval. This does not mean that they will and "prolonging" the QT interval is not the same thing as having a "prolonged QT interval".
Avatar f tn 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!
Avatar f tn I would also check your EKG to see what the QRS duration is -- often when people have mobitz type I, the QRS is also widened, which would “stretch out” the QT interval -- a prolonged QT in this setting would not be considered a true QT prolongation.
Avatar f tn Every person have their unique relationship between QT interval and heart rate. In some people, QT interval narrows much with increased heart rate and in some people it doesn't.
Avatar m tn Actually, I think your qt interval might be in the normal range. According to wikipedia, the normal range is between 350 and 440 milliseconds. Keep in mind that long qt syndrome, which is the actual worry, can occur in people with relatively normal QT intervals. Wikipedia describes a point system that is used to diagnose people, but in some cases genetic information may be the deciding factor. To your heart rate statement, 0.
Avatar n tn My Vent rate was 89 bpm RR interval was 670 ms PR Interval was 178 ms QRS Duration was 84 ms QT Interval was 346 ms QTC Interval was 396 ms QT Dispersion 18 ms P axis was 29 deg QRS Axis was 17 deg and T axis was 0 What does it all mean??
Avatar m tn What do you mean by "EKG showed problems with QT intervals"? The reason I ask is that the QT interval has to be corrected using something like the RR interval to have real meaning. RR is just the time interval from beat to beat, and if you have bradycardia there might need to be more correction going on. On the other hand, some drugs affect the QT interval. If you do have a prolonged QT caused by drugs, I should think it should be reversible when you stop taking the drug.
Avatar f tn The ECG showed repolarization disturbances, negative, flat or low negative T in V3, V2, V4, V5, and V6 and long QT interval. They were talking about admitting me, but couldn't get a bed, so I was told to go home and if I had another severe attack to go to the ER by ambulance. Since then, I have continued with the palpitations, lightheadedness, and some blurring of my vision, but nothing as severe as the near fainting incident. The slightest bit of excertion brings on an episode.
Avatar n tn There are a number of things that could cause the QTc interval to be too long. (QTc just means QT interval corrected for HR, with the point of reference being 60BPM). In your case 404ms at 78BPM corresponds to 460ms if your heart was beating 60BPM. It is the QTc, not the QT that is important. Certain genetic mutations that affect the potassium or sodium ion channels could cause this problem. That is what happens in Long QT Syndrome. However, this does not seem to be likely in your case.
Avatar f tn The doctors took an ECG which showed a prolonged QT interval. The QTC was 536 ms (supposed to be below 460) but the doctors said that its nothing to worry about an to continue with exercise. An echocardiogram showed trace mitral valve regurgitation but apparently thats also harmless. However, now I still get a racing heart with any exertion (174 bmp walking up 3 flights of stairs, 120 bpm walking around the house). My resting heart rate is 65-69 bmp.
1425157 tn?1311651679 Hi,I have a history of pvc and pac i take atenolol 50 mg a day for this,no high blood pressure ,,i have had many ecg and a few holters and an echo,,and an av node signal average test,,no one has ever mentioned a long qt interval before -i am haveing gall bladder surgery soon and as a precaution they sent me to internist who ordered this last holter,saw clinic doc today for results he said it showed a long qt interval and he did and ecg then and there- no long qt on that one -i was haveing an an
Avatar f tn Too low blood calcium can cause prolonged QT interval. Have you measured your calcium with blood tests? Could there be a reason for low calcium? It's very important that you get this investigated.
Avatar f tn Risperidone is on the list of drugs to be avoided if you already have a prolonged QT interval, however, it is not known to prolong QT interval if you do not have this condition. Some typical antipsychotics (for example chlorprothixene/Truxal) require an EKG before treatment, but risperidone does not. I should add; unfortunately there are other causes of sudden arrhythmic cardiac death which do not involve the QT interval (for example Brugada syndrome).
Avatar m tn In general, the newer antidepressants (SSRI and SNRI) do not prolong QT interval so much. A possible exception is citalopram (and escitalopram). As far as I know, paroxetine and vortioxetine are fairly safe. How long is your QT interval?
Avatar f tn Hello. Yes, you should contact your doctor, and possibly get a 24 hour heart rate monitoring, to see how your heart rate changes during 24 hours. An extra reason for concern is the QT interval (did you have a prolonged QT?) in which setting it's not desireable with a too slow heart rate, because the QT interval further prolongs with slower heart rate. That said, if you recently lost 100 pounds and is exercising almost every day, the results aren't necessarily abnormal.
