Practice EKG Strips
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.
