Long Qt Syndrome (Overview)

A heart-rhythm condition that can potentially cause fast, chaotic heartbeats. These rapid heartbeats might trigger a sudden fainting spell or seizure. In some cases, the heart can beat erratically for so long that it causes sudden death.

What is long qt syndrome?

Heart rhythm problem: Long qt syndrome (lqts) is a congenital disorder of the heart's electrical activity that is characterized by prolongation of the qt interval (delayed repolarization) on an electrocardiogram. Delayed repolarization of the heart following a heartbeat increases the risk for sudden, uncontrollable, dangerous heart rhythm disturbances in response to exercise or stress. ...Read more

How do the symptoms differ in anxiety vs long qt syndrome?

How do the symptoms differ in anxiety vs long qt syndrome?

See MD: Prolonged qt is a rare, but very serious medical disorder. Symptoms can be dizziness, lightheadedness and passing out. Anxiety symptoms can be similar, but increased heart rate, sweating, shortness of breath, etc. Anyone having symptoms like these should see their doctor for a full evaluation. ...Read more

I have long qt syndrome & an etopic beat, I get a lot of chest pain & pressure in my chest. Is this a bad sign? My gp won't refer me to cardiologist.

I have long qt syndrome & an etopic beat, I get a lot of chest pain & pressure in my chest. Is this a bad sign? My gp won't refer me to cardiologist.

Cardiologist: Long qt syndrome is a risk factor for arrhythmias, and if you are also experiencing chest pain/pressure you do need to see a cardiologist. You need an ecg, echocardiogram, blood tests for electrolytes and thyroid function, and a holter monitor to start the work-up. Further testing such as electrophysiologic study (eps) would be at the discretion of the cardiologist. ...Read more

If I get an ECG test for long qt syndrome will I know the result the same day?

If I get an ECG test for long qt syndrome will I know the result the same day?

Possibly: The ECG machine will automatically interpret the QT interval, but can be mislead. If there's any doubt, you may have to wait a day or two for the official interpretation by a cardiologist or heart rhythm (EP) doctor. Finally, the test must be taken in context with history & other tests, so reassurance may not occur until further discussion with your doctor. Call 911 if passing out spells. ...Read more

When you have long qt syndrome diagnosed, do you always have to start medican for it?

Talk to cardiologist: This is an area that is constantly evolving. The answer to this is complex, an requires an informed discussion with your cardiologist and possibly even an electrophysiologist. A short answer would do a disservice to the complexity that is involved here. Most patients with long qt syndrome receive medication and some require an internal defibrillator. ...Read more

Do antibiotics and heart meds cause long qt syndrome?

Do antibiotics and heart meds cause long qt syndrome?

Secondary Long QT: Both can. Several antibiotics and antiarrhythmic medications, and other medications, can prolong the qt interval on the ECG increasing the risk for certain, potetially life threatening, heart rhythms. Secondary long qt (from meds) can be made worse when taking certain heart medications (antiarrhythmics) and then adding antibiotics to the mix. Ask md if new medications are ok to add. ...Read more

How is treatment of long qt syndrome different from treatment of arrhythmias?

May be same: Long qt syndrome is a spectrum of genetic conditions that result from gene mutations affecting how electrolytes are handled in heart muscle cells (there are >8 types of these). Most of these mutations predispose to potentially life threating arhrythmias occuring with mild provocation. Some of these may be preventable with arrhythmia medications and some require electrical cardioversion (icd). ...Read more

Going to see ep dr for possible long qt syndrome I am taking celexa (citalopram) (10 years) which is a drug to avoid for lqts what can I do until appt to avoid sca?

Going to see ep dr for possible long qt syndrome I am taking celexa (citalopram) (10 years) which is a drug to avoid for lqts what can I do until appt to avoid sca?

More information: Much more information is necessary to be able to answer your question. 1) do you need the celexa (citalopram)? 2) is there a history of any ventricular arrhythmia or possible ventricular arrhythmia? For instance, have you ever had syncope (fainting)? 3) is there a family history of sudden cardiac death? 4) do they think you have long qt syndrome, or just a long qt interval on an ecg? Good luck. ...Read more

My brother has long qt syndrome. How great is my (and my kid's) risk of having it also?

50%: Lqts is due to a genetic abnormality of one of the channels that moves electrolytes across the cell membrane of heart muscle cells. These defects typically are inherited in an autosomal dominant fashion. It is possible that your brother has a de novo mutation. If your brother inherited lqts from one of your parents, though, you have a 50% risk. Your son's risks are dependent on your status. ...Read more
