I had a pneumothorax after a lung needle biopsy. I decided not to have the chest tube but go home from hospital to rest to heal on its own. The day after the pneumothorax I have heart palpitation, it is worse after eating. The only time I don t feel it is when I am sleeping or resting. The last check with my lung doctor after x-ray, I was told my lung is fully expanded, and the lung sounded ok. However, my heat palpitation is really bothering me. Was it caused by the pneumothorax, and will it ever get better?

Summarized question: What causes heart palpitations after pneumothorax?
