I get PAC's and PVC's. Without watching which hiccup is which on a monitor, I'm not sure what they feel like. I get the ka-bam with the long pause and I get the little heart flutter. Much depends on where the premature signal occurs in the cycle. Some of my PVC's are not bad, some hit me hard.
If you only get PAC's, then what you're feeling is probably a good indication of what you can expect.
