I have been diagnosed with sick sinus syndrome. I was on diltiazem xt 120mg. I stopped taking the medicine 12 days ago could it still be in my system and be causing slow heart rate 40-45 during th day.
I believe the half life is about 18 hours depending on which type you take. That means within a couple of days there's such a small amount left in the body, it probably isn't doing much any more. I know when I stopped my Diltiazem I started having chest pains again within 3 days. I was also on the 120 ER, extended release. How long were you taking the med? And sick sinus can also cause slow HR in itself. Are you symptomatic - light headed, fainting?
I had been taking it for 6 months. Not for chest pain but for Raynaud syndrome. I have been off for 12 days. I am a little light headed. The Dr says its sick sinus syndrome and I am scheduled for a pacemaker tomorrow. I am last minute looking for anything else this can be maybe causing a temporary slow heat rate. It was only detected 4 weeks ago.
Ok then. Diltiazem does work pretty well for the Raynauds (I have it also) but not so good for sick sinus. I have Raynauds and arrhythmias. I noticed my PSVT wasn't so bad, the chest pains went away and the Raynauds improved during the 3 months I took it. But my heart rate did slow way down at times while on the med. So with your sick sinus syndrome, the doc may want to hold off the Diltiazem till you get the pacemaker. Keeping your rate up and steady is pretty important.
Is your Raynauds primary or secondary? Has the doctor mentioned putting you back on the med after the pacemaker is installed? Honestly, you will feel better once you have it and your heart rate does what it's supposed to do. Stay in touch and let us know how it goes tomorrow. Remember - don't lift your arm. :-)
Thanks I will . They have not discussed putting me back on the medicine after the pacemaker. They are sure that the medicine did not cause the sick sinus and it did not seem to make a difference in my heart rate after I quit the medicine. I hope I will feel better but the problem is I dont really feel bad its just my low heart rate. 40-50 day and it goes as low as 29 at night after wearing the monitor.
