The electrocardiogram and the severity of COPD

From the Annals of Noninvasive Electrocardiography:

Methods: ECGs were interpreted blindly in 63 patients with severe COPD (group 1) versus 83 patients with mild or moderate COPD (group 2).

Conclusions: RAE, RVH, RBBB, marked clockwise rotation of heart, a QS pattern in leads III and aVF, LAD, PACs, and SVTs were significantly more prevalent in patients with severe COPD than in patients with mild or moderate COPD.
