I have a cardiac defibrillator for Long Q-T Syndrome.
Suboxone, even though has not been studied as extensively as Methadone, has not been shown to cause prolongation of the Q-T interval. Methadone is totally contraindicated for patients who have been diagnosed with Long Q-T Sydrome, as the drug itself CAN cause the QT interval to become longer. What this means is a very very small percentage of patients may have complications, in the form of a lethal arrhythmia, from Methadone. Every one on Methadone should have an EKG to measure the interval before/after starting Methadone. I discussed this with my cardiologist who is an electrophysiologist…..
This does not seem to be a problem with Suboxone. Many people experience minor palpitations and tachycardia during withdrawal due to the irritation of the sympathetic nervous system. Many people are placed on clonidine and beta blockers and monitered by their doctors for the withdrawal period. AFIB does not appear to be related to Suboxone use.
Any one with a symptomatic*, irregular heart beat should be seen by a doctor and evaluated with EKG or holter moniter to determine which type of arrhythmia it is, echocardiogram, to look for functional abnormalities (esp those with AFIB) and a thyroid and electrolyte profile, especially potassium, sodium and magnesium. I know, it all costs a ton of $.
Hope none of you are having these types of problems. I’m not a doctor, but have many years experience with this syndrome.
*dizziness, fainting, prolonged racing heart, tachycardia at rest, family history.
