I have chest pain, pac's, pvc's and non-sustained A-fib along with sinus tachycardia that was finally caught on an event monitor, so I was prescribed 18O mg. once daily, but I still get the sinus tachycardias, etc. I even had one episode where my heart raced over 170 bpm. That was never caught though on a monitor.
Would increasing the dosage to maybe 180 or 240mg make a difference. The 120mg used to work when first prescribed. But, now I have all these arrhythmias back again... along with more chest pain. Should I just switch to another calcium channel blocker or have doctor increase dosage. I would appreciate any advice :)
