I am struggling with PACs myself. The answer to your question may be what is you total burden? That burden would be listed as a % of total beats in a 24 hour period that are PACs. My burden was listed at 22% PACs and 2% PVCs. That means nearly 1/4-25% of my heart beats in a 24 period are aberrant. That is consider high. My resting HR is 50 beats a minute. So you have to take you resting HR and find the total beats for a 24 hour period. The amount of PACs you report for a 24 hour period is then divided by that number of total beats 24 hour period. You really need a monitor to get it correctly. So for example if your resting HR is 75 BPM and you experienced 20,000 PACs in a 24 hour period that would equal a burden of 18-19 % if my math is correct. My EP recently said it is nearly impossible to do ablations on PACs. He claimed that you have to literally be looking at the heart at the right place at the precise time it is creating a PAC in order to ablate it. Yet I read plenty of articles discussing ablation of PACs. So if mine continue I will push the discussion with him about an ablation. It negatively affects my quality of life especially resulting in poor perfusion resulting in making me tired and on edge.
