The patient is a 70-year-old man with a history of smoking
and COPD who presented with cough, sputum production,
and shortness of breath. Physical exam was notable for
low grade fever, oxygen saturation of 94% on 2 liters
via nasal cannula, and diffuse expiratory wheezes on lung
exam. He was admitted for COPD exacerbation secondary
to acute bronchitis. Admission EKG was initially interpreted
by the computer as Mobitz type I 2nd degree AV block.
Prior EKG’s showed normal sinus rhythm with right
bundle branch block.
On further examination of the EKG,
what is the correct interpretation?
