Practice EKG Strips





Answers

Sinus rhythm with competing junctional rhythm.  The rhythm is slightly irregular with a rate of about 50 bpm.  The P wave of the first complex looks biphasic but the P waves of complexes 2 – 4 are entirely negative.  Complexes 5 and 6 have upright P waves and are thus sinus in origin.  The rhythm flips back to a junctional rhythm.  There is some ST depression with some T wave inversion in lead II. The QRS is a little wide, perhaps an incomplete RBBB.
