Avatar f tn At this stage, at the current level of QT, I would suggest it is wise just stop zoloft for few days, let’s say a week, and recheck QT. If it normalizes, and especially if it gets prolonged on reintroduction, then it proves the causal hypothesis. You will need to stop and avoid zoloft and preferably all SSRIs if possible. As of now you have very low risk of torsades de pointes and need not worry much unless you develop some symptoms.
Avatar n tn Both Celexa and Effexor are drugs known to cause QT prolongation. QT prolongation can lead to ventricular arrhythmias causing fainting, seizure-like activity and sudden cardiac death. Hypothyroidism is also known to cause QT prolongation. I would probably seek a second opinion on this and get an ECG done to make sure that you don't have a prolonged QT interval.
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 n tn Erythromycin and Cipro are both on the QT drug list that can cause prolongation of the QT interval on an ECG and can cause the arrhythmia Torsades de pointe. This is usually worse for patients with Long QT Syndrome or for people taking anti arrhythmic drugs or other drugs also on the QT Drug list. Check it out at www.****.org.
1561081 tn?1351038313 ) You need to stay in close touch with your doctors, and report any abnormal findings. There are degrees of prolonged QT, and different types of LQTS, with different arrhythmia triggers. Take care.
Avatar f tn Spicy foods and foods that cause acid reflux. Becoming dehydrated and over extending self working out. and stress and anxiety. Many people have PVCs daily some a lot more than you are experiencing so they can be lived with. PVCs can be very scary but they are generally benign in an otherwise healthy heart. I would suspect if you stay heart healthy you need not worry even with long qt but in life there are no guarantees.
1124887 tn?1313754891 However, others have suggested the upper limit of normal be set at 450 or even 460. Zoloft is known to prolong the QT interval. However, I would not consider prolongation of the QT interval to 388 ms to be of any clinical significance and would tell one of my patients to not have any anxiety about that change. In regards to QT dispersion. the QT interval varies from lead to lead. The QT interval can vary by up to 65 msec in normal people between leads.
Avatar f tn Treatment with Methadone can cause arrhythmias, bigeminal rhythms, extrasystoles, QT interval prolongation, T-wave inversion and ventricular tachycardias. So, please follow up with your doctor and have an EKG done, so that he can check to see if there are any new rhythm abnormalities as compared to your previous recordings. Hope this helped and do keep us posted.
Avatar f tn Some individuals with MVP are often predisposed to electrocardiographic abnormalities of ventricular repolarization, which requires annual cardiologic evaluation. Its not uncommon for healthy subjects to have a QT interval above the limit. MVP is associated with PVC's and mild QT prolongation and is not uncommon (about 5% of the population). Don't stop taking your medication, and consult with your doctor regarding MVP and the concomitant long QT interval...
789911 tn?1368636783 This is the drug I was prescribed for nausea during treatment. Thank goodness I am not having continuing problems with nausea. Something to look into to be aware! WASHINGTON -- A drug used to treat nausea and vomiting caused by chemotherapy may trigger dangerous and possibly lethal changes in heart rhythms, the FDA warned Thursday.
250701 tn?1320974765 Caution is warranted and clinical monitoring is recommended when co-administered with telaprevir. QT interval prolongation and Torsade de Pointes have been reported with clarithromycin and erythromycin. QT interval prolongation has been reported with telithromycin. http://pi.vrtx.com/files/uspi_telaprevir.
Avatar f tn It has been known that anti-phsycotic drugs especially risperidone have been known to lengthen the q t interval and cause sudden death also with people with a family history of sudden death( which our sister died of unexplained death(cot death) age 4 months) can heighten the risks of qt prolongation. If this is the wrong forum could someone please tell me where go to next or who can help me with my query.... i'm not looking for an answer but to a possibility.
Avatar m tn Diagnosing LQTS in a patient with a borderline QTc (440 ms to 460 ms) is difficult and further testing is usually needed to determine whether the patient has QT prolongation and congenital LQTS. Factors that can increase the probability of having LQTS include resting ECG findings (specially QTc ≥480 ms), treadmill exercise test findings, history of recovered sudden death, syncope (passing out) with or without exercise, family history of LQTS or sudden death.
Avatar n tn I can not explain why the doctors changed the report with a QTc of 449 msec and then when the next day was 459 msec as I have not seen the EKGs, but it may be related to the value given by the automatic report of the EKG machine (that should not be used to diagnose QT prolongation) and the measurement done by the doctor.
Avatar n tn Xopenex is beta-2 adrenergic agonist and Pulmicort is corticosteroid, although they are often combined in clinical practice, the concomitant use of beta-2 adrenergic agonists and corticosteroids may result in additive hypokalemic effects. Since beta-2 agonists can sometimes cause QT interval prolongation, the development of hypokalemia may potentiate the risk of ventricular arrhythmias including torsade de pointes. However, clinical data are limited, and the potential significance is unknown.
4451049 tn?1387153437 Cardiovascular side effects have rarely included arrhythmias (including ventricular tachycardia), prolongation of the QT interval, torsades de pointes, palpitations, hypotension, and chest pain in postmarketing experience. A causal relationship has not been established.
Avatar f tn Should I avoid such medicines that cause prolongation of QT? I should take a one time pill of Diflucan for tongue trush. Is it dangerous?
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".
996946 tn?1503249112 I do have prolonged QT and Diastolic Dysfunction. I did cancel the stress echo but called and got the appt back for tomorrow at her office. I have weaned down to 200 mg a day on the flecainide. I'm scared of it bringing on a-fib...which I have not had in 2 months...but I guess the Dr knows what she's doing. If I don't show back up on MH by Wed. we'll all know why.....
Avatar n tn It was the EP dr who read the ekg while I was in his office. He requested that I wear a holter monitor for 24 hours but haven't gotten results back yet. I am assuming no news is good news. Today, I went to my cardio's office for my weekly ekg and QT / QTc intervals was within normal limits. Can QT / QTc intervals be prolonged one time and normal the next time? I have had three prolonged intervals in the past 6 months but also several normal ones.
Avatar f tn Hello, I went to a new pcp for a checkup and he heard a heart murmur, which he said was probably normal but told me to see a cardiologist to be safe. He also told me the nurse was going to give me an ecg before I left. I had the ecg and left the office. About 20 minutes later the receptionist called me and said the doctor wanted me to come back to get the ecg results to take to the cardiologist. He had writted "prolonged QTc" on the ecg.
1900997 tn?1321659956 If you note in the article, concerns of the elderly are expressed concerning QTc prolongation in relation to dose and age. Though by no means am I suggesting your 45 years is equated to being elderly, it does suggest that change can occur with age, as the concerns about the phenomenon in those 60 and older is addressed. If I were in your place, I'd see about a reduction in the dosage of Citalopram and retesting at the doctor's recommended interval. http://cpnp.
Avatar m tn Only sleeping 3 to 4 hours a night for the last 3 weeks and then Im up and down all night. So very dehydrated. Drinking 70 to 80 ounces of water a day. weight is 136. Have lost 8 lbs so far.
Avatar f tn Several of the changes that can happen in the conduction system include bradycardia (slow heart rate), abnormal abnormal ECG waves, prolongation of the corrected QT interval QTc), and arrhythmias (some of them lethal). A U wave can actually be a normal finding. It is a wave found after the T wave (the waves routinely seen on the ECG include the P wave, the QRS complex, and the T wave).
