Unresponsive and Bradycardic - EKG challenge #1

An elderly lady is brought in by EMS minimally responsive.  The only VS that  you have are a blood pressure of 80/60, HR of 36, and a oxygen saturation of 100% on NRB. She received atropine 0.5 mg x 3 in the  field with no effect. You obtain the EKG above. Interpret the EKG. What are your diagnostic considerations?  What other information do you want?  What are you doing to stabilize the patient?
