I am a female 34yrs. I have a pacemaker for SND. I seem to be having a number of arrythmia problems, despite meds. including amiodarone, and cartia for rhythm. I have asthma so cannot take beta blockers, and developed long QT with tykison. Have done, rhythmol, tambocor, sotalol and the one that worked the best thus far has been amiodarone. Now however, I am not responding so well to it.
I am getting alot of arrythmias, and I am wondering if a person can develop a tolerance? I am at the highest dose they will allow 400mg.of amiodarone with elevated liver enzymes.
My last 24 hr. holter showed 2000 wide complex beats with couplets, triplets and runs of sustained wide complex tach. I have a-fib. Is it possible to know for sure if this wide complex rhythm is v-tach, or a-fib with aberancy without an EP study? My ventricular rate gets up to almost 300, and I don't feel well. When this occured at one point while I was being monitored I had a relative drop in systolic pressure (20-mm).
What is the signifance of this report?
Is a relative drop in blood pressure acceptable when I get this problem at home? Can I just wait it out?
Are there any further steps that can be taken at this point?
Thank you so much.
