Question

19. P-P Intervals R-R Intervals QT QRS PR ST Segment changes (if any) Rate Rhythm Interpretation:

Answer 1

p p interval - 840ms or 0.84 second

R - R interval - 840 ms or 0.84 sec

Q T interval - 240 ms or 0.24 sec

QRS - 60ms or 0.06 sec

PR interval - 160ms or 0.16sec

ST segments changes - There is no st segment change.

Heart rate - It is approximately 80 beats per minute because according to RR interval.

Rhythm interpretation - Rythm is regular but there is PVC(Premature ventricular contraction) in between. It means heart rate initiated from Purkinje fiber instead of SA node.
