Why when i get a pvc i feel a quick instant loss in breath and sometimes cough? this is so scary and starts my worry and anxiety

Lung disease and PVC: Actually, the underlying lung issue (copd, asthma, bronchitis or emphysema) can be one of the causes of premature ventricular contraction, which is the result of the left ventricle of the heart contracting too early before receiving the expected signal from the sino-atrial node. Hypoxia, or a lack of oxygen in the blood, can lead to this issue.
