Everything related to resuscitation, and resuscitation based activities.
At this stage things are progressing nicely. In the previous two articles we learned about The Anatomy & Electrical System and then The Electrocardiograph. In the last blog we used the analagy of the mugshot to describe how it is important to view the heart from different perspectives to give us a better understanding as to whats actually happening. We also mentioned that the mugshot pictures were always taken against a height chart. This helps put things in perspective for us.
You may well be wondering what an mugshot has to do with an ECG! Well don't worry the answer is contained within...
In this ECG tutorial we will cover the fundamentals of the Electrocardiograph. In the last tutorial: ECG Tutorial 1: Anatomy & Electrical System we discussed the gross anatomy and electrical conductivity of the heart. If you are not familiar with content of that tutorial I would suggest that you go back and read over it again as this tutorial will build on that information.
We have omitted some information that while useful, is of more use to people studying and interpreting 12 Lead ECG's. This tutorial is primarily aimed at people learning 3 Lead ECG's.
This ECG Tutorial blog is the first in a series, designed for people who wish to learn something new or simply to refresh material already learned. It may be particularly useful to first responders, emergency medical technicians or student paramedics. During the course of this series we will be focusing on the basics of ECG along with discussing rhythm strips and 3 and 4 lead ECG's.
It's not going to turn you into a mega super ECG guru! But it will provide you with a good understanding of what exactly you are looking at on a rhythm strip and how that corrosponds to different actions within the heart. It is hoped that in the future we will also incorporate a 12 lead ECG section into this blog series. But thats a bit down the road yet.
OK, enough talk let's kick off.
