Question

اممممممله Rate:110 bpm PR Interval: QRS: Arrhythmia/Interpretation:

What type of arrythma does this ecg display?

Answer 1

The PR interval is the start of P way to the start of QRS complex.

One small box=0.04 second

Here the no of box is 5 ,so multiply with 0.04

=0.2 second (normal range is 0.12 to 0.02 seconds)

The QRS normal range is 0.06 to 0.12 seconds .It is considered to be 1.5 to 3 boxes

As 1 box =0.04 second

Here there is 1box and a half box ,so it measures 0.04 +0.02= 0.06 seconds

Interpretation

In ventricular depolarization some of the waves are upside and some waves may be down side.This is also called as biphasic.As 2P wave is found for 1 QRS complex, it is a second degree heart block or AV block.This is an ventricular arrhythmia.
