PACs when I inhale

Hi, I have been having some heart concerns over the past few months, including PACs and tachycardia. After 7 EKGs, a stress test, an MRI (for pulmonary embolism), blood tests, chest x-rays, and a 24 hour event monitor, they decided it is a combination of an anxiety disorder and alcohol abuse. This morning, while driving, whenever i took a deep breath my heart skipped a beat like a PAC. I can see the occasional PAC and a rapid heart beat, but skipped beats when I inhale? That seems a bit extreme of a symptom for alcohol withdrawal and anxiety. Does anyone have any insight to this, or have they experienced something similar?

It is normal for the HR to increase slightly on the inhale part of breathing.... as the lungs have maximum oxygen during this period.  Most of us, myself included, are totally unaware of the breathing modulation on our heart rates. This effect may be what you interpret as a PVC.

I have been diagnosed with occasional PACs by my doctor, and you are right in saying I am aware of my heart rate. Along with that though comes an awareness of what the different beats feel like, and for about a 15 minute period whenever I inhaled deeply I had a PAC.
