Are you physically fit, do you work out?
Do you know what your blood pressure is?
i work out every day, but i was recently told me bp is alittle high...
Again they said it was stress.
People that are very fit will have a low BP however you are correct in saying that (rarely) lexapro can cause slow heart rate. You mention that you are always tired and that may be related to your lexapro too. Or it may be related to the slow heart rate
First off, do not stop this drug by yourself as you will just end up with withdrawal symptoms however I do think that you need to discuss this with your doctor and either reduce the dose or plan a withdrawal strategy. After 7 years on this drug, it is to be hoped that the need for the drug is lessened and that phased withdrawal is appropriate.
It can cause changes on the ECG, but you mention that you hsve recently had an ECG so they would have seen if that was the cause.
Aside from the slow heart rate and the change in ECG pattern, this drug has actually got reduced heart side effects compared to some of the other drugs used. I would not get too stressed about being on it, however it is something that needs to be discussed.
It is the tricyclic antidepressant class of drugs that has predominantly been associated with this problem. The only relationship to lexapro was in the case of overdose, and the problem is linked to changes in ECG which would have been noted at your recent check up.
I would say that this particular drug in your case is unlikely to lead to sudden cardiac death.
