I just met with my new doctor yesterday. He said he’s 100% sure that postural ectopic beats are real. After over 20 years of practice he said he has witnessed it in so many patients. He believes it has to do with the vagus nerve and how in different positions it can trigger the heart and how it beats. He says he’s heard the argument that people just don’t notice it during the day and only when resting in bed at night become aware and he doesn’t buy that explanation. For one thing, as I said above, sitting on the exam table my heart beats normally. Lie me down on the table and boom, PACs. He’s seen that over and over. I was glad to hear a doctor acknowledge what so many patients experience. Just because the mechanism is not understood doesn’t mean it’s not real but that is exactly what so many doctors do.
