My husband had a heart attack in 2012 followed by bypass surgery. He went into afib and has had two cardiac ablation surgeries and has been out of afib for over a year. He has a difibulator and just learned he was in afib for the first time yesterday and a slight flutter at his check up today. He also suffers with sinus infections. Can blowing your nose extremely hard effect your heart. I just want to rule out this would do anything to his heart rhythm. Thanks
