The rhythm is regular. The rate is 78/min. There are upright P waves before each QRS complex. No ectopic beats are noted. The PR interval is prolonged at .32 sec, QRS: .08 sec, QT: .40 sec.
2.
There is electrical interference present. The patient had his lap top sitting on his chest.
3.
The rhythm is irregular. The rate is 110/min. The are no readily identifiable P waves present. Fibrillatory waves are noted, especially towards the end of the strip as the rate slows down. No ectopic beats are seen. PR: --, QRS: .08 sec, QT: .34 sec
4.
The rhythm is irregular due to the ectopic beats. The underlying sinus rhythm is regular. The calculated rate is 75. There are upright P waves present on the regular beats but no P waves on the ectopic beats. The ectopic beats are wide and bizarre indicating a ventricular origin. The PVCs occur every 4th beat. PR: .20 sec, QRS: .10 sec, QT: .40 sec.
5.
The rhythm is regular. The rate is 150/min. No P waves or ectopic beats are noted. PR. ---
QRS: .08 sec, QT: .26 sec. The V! lead clearly does not show any P waves. However, the rhythm could be classified as either an atrial fibrillation with RVR or a junctional tachycardia. Because it is not clear where the rhythm originates from it is generally called a supraventricular rhythm.
