The rhythm is regular. The rate is 88. There are not any P waves. The QRS complex is narrow, 0.08 sec, QT: .42 sec. Because the rate is between 80-100 and there are no P wave, this rhythm is identified as an accelerated junctional rhythm.
2.
The rhythm is regular. The rate is 50. There are inverted P waves before each QRS complex. QRS: 0.08 sec. QT: 0.40sec. Inverted P waves are a signature of a junctional focus. Because the rate is between 40-60, this makes it a junctional rhythm
3.
The rhythm is regular. The rate is 107. There are no P waves before each QRS complex. QRS: 0.10 sec QT: .40 sec. Based upon the rate and the absence of P waves, this makes this a junctional tachycardia.
4.
The rhythm is regular. The rate is 71. There are no P waves before each QRS complex. QRS: .08, QT .40. Interpretation: accelerated junctional rhythm
5.
The rhythm is regular. The rate is 40. There are inverted P waves preceding the QRS complex. QRS: .08 sec, QT: .40 sec. The rate and inverted P waves are characteristic of a junctional rhythm.
