Postural arrhythmias

My electrophysiologist does not believe that people have worse PACs, etc. when they lie down. He believes people just don’t notice them during their busy day. I’m someone who feels my heart whenever I’m quiet and I have always had increased PACs when lying down. Right now, two months post ablation, my heart is not happy when I’m trying to go to sleep. It pounds or races or I have relentless PACs. I have Atenolol prescribed to take as needed and that helps. But it’s also causing hair loss. Help! I’m very frustrated and discouraged that all this is happening after my double ablation. And I really don’t want to lose my hair. It doesn’t help when my doctor doesn’t believe in postural ectopic beats. Or hair loss.
