ECG Interpretation and Cardiac Rhythm Recognition

ECG Interpretation or ECG Analysis Can be Tricky

ECG interpretation or ECG analysis and rhythm recognition is something that many people find extremely hard if not challenging. This need not be the case and I can provide you with a resource that will make it a breeze!

My aim is to make ECG interpretation also known as EKG interpretation a lot easier for everyone. I ensure that all the necessary steps that need to be taken for ECG analysis or rhythm recognition are set out in clear and concise manner. Anyone who follows these steps can be fluent in ECG analysis, ECG interpretation and rhythm recognition.

ECG Interpretation

Do you find ECG Interpretation puzzling? It need not be!

ECG Interpretation and rhythm recognition: How I can help you!

I have a mass of cardiology and cardiothoracic surgery and critical care experience totaling over 14 years. I have worked as an educator in all of my places of work and as such have the experience and knowledge to help anyone grasp this sometimes tricky subject.

I have recently written an e-book of ECG Interpretation & Rhythm Recognition. In addition to the e-book, there is also a paperback version of the ECG Interpretation and Rhythm Recognition resource.

These books cover all of the major cardiac rhythms and ECG’s that you are likely to come across. See below for a sample of the resource. This book will help you in your EKG interpretation and ECG analysis.

ECG Interpretation and Rhythm Recognition

This e-book of ECG Interpretation & Rhythm Recognition, and the paperback version of ECG Interpretation and Rhythm Recognition is extensive and is perfect pocket or study guide for any health care professional or allied health worker wanting to increase their ECG analysis skills.

Any patient that presents to an acute care facility will undoubtedly have an ECG in their case file. Knowing how to take one and how to perform ECG analysis is imperative to gain a better understanding of the patients’ current or past condition. ECG interpretation and rhythm recognition is an essential skill!

This ECG analysis, ECG interpretation and rhythm recognition e-book is a simple, concise and affordable option for you. Get your copy of ECG Interpretation & Rhythm Recognition or the paperback version of ECG Interpretation and Rhythm Recognition here!

ECG analysis and ECG interpretation information needs to be available at the point of care and as such this resource needs to be portable. I have created an EKG interpretation and EKG analysis e-book that can be used on any portable device including a Kindle, or an iPad – it can be viewed on an iPhone, Android device, PC, Mac, e-book reader device and many other devices with the use of the free Kindle reading apps. Alternatively just order the EKG analysis and EKG interpretation paperback version, which is also the cheapest on the market and just as concise as the others available today! If you do own a Kindle, you can just download and view the book, however if you want to view the resource on any other device then you will need the free Kindle reading apps.

As you have come this far down the page and due to popular demand I am going to let you have a sneak peak inside the book:

Please note that the formatting of the resource is a lot better in the book, this is just for display purposes!

Foreword
I am a clinical nurse specialist working in a major tertiary referral centre within Australia. I qualified in 1998 and since then I have been working in critical care, more specifically in a coronary care unit, cardiac high dependency units, cardiothoracic intensive care units, a paediatric and a general intensive care unit. In addition to this I have worked as an educator in all of my places of work.

I believe that ECG analysis and ECG interpretation is a relatively simple task which can be taught to anyone given the right instruction and information. Whether you are studying for an assignment, working in critical care, or just wanting to further your ECG analysis knowledge then this simple book will teach you exactly what you need to know in an easy to understand step by step process. The examples of specific rhythm strips and ECG’s will be given with reference to actual ECG’s so there will not need to be any guesswork on your behalf to perform the ECG analysis and ECG interpretation.
This book is not necessarily designed to provide extensive explanation for the specific rhythms and ECG’s, it was made for identification purposes only.

Basic Rhythm strip analysis

Normal Sinus Rhythm

Before we start to perform any ECG analysis or ECG interpretation we need to establish what a basic rhythm looks like. The basic rhythm is normal sinus rhythm, which consists of a P-wave, QRS complex and a T wave.

PQRST

PQRST as part of the EKG analysis resource

The P wave represents atrial depolarisation, or electrical firing.
The QRS complex represents ventricular depolarisation, or electrical firing. The normal width of this complex is less than 3 small squares, which is 0.12 seconds.
The T wave represents ventricular re-polarisation, or getting the cells ready for another depolarisation.
The PR interval is the time interval between the P wave and the onset of the QRS, which reflects the time between sino-atrial (SA) node and ventricular depolarisation. Normal duration is between 3 and 5 small squares (0.12 – 0.2 seconds).
The SA node is responsible for (in normal sinus rhythm) atrial depolarisation. The AV node (in normal sinus rhythm) initiates ventricular depolarisation.
To read the rhythm strip you need to, as with most things, follow a systematic approach. The method of analysis that I advocate is the following:
1: Is there a P wave?
2: Is there a QRS complex?
3: Is there a T wave?
4: Is the rhythm regular?
5: Is the rhythm regularly regular (is there a regular pattern that the potentially irregular rhythm follows)?
With normal sinus rhythm there is a P wave, a QRS complex, and a T wave. The rhythm is regular, and it is regularly regular.

Normal sinus rhythm generally is at a rate of between 60 and 100 beats per minute. To establish the rate of the rhythm, count the number of large squares between the point, for example R to R, and divide this into 300. To demonstrate this with the prior example, there are almost 4 large squares between R points, therefore 300 ÷ 4 = 75 beats per minute.
An important note when analysing a rhythm strip is that whenever you are unsure if there is a T wave, if you see another QRS complex then there must have been a T wave. This is because without a T wave there would be no further ventricular depolarisation or electrical firing. The reason for this is that the myocardial cells need to reach the correct electrical charge to fire again.

Sinus bradycardia

This rhythm is the same as normal sinus rhythm, however the rate is less than 60 beats per minute.

Sinus tachycardia

This rhythm is the same as normal sinus rhythm, but the rate is greater than 100 beats per minute.

Atrial flutter

Atrial flutter is a rhythm that has definite P waves (which in atrial flutter are actually referred to as F waves) which are saw–tooth in appearance. There are QRS complexes and T waves. The ventricular rhythm may be regular or irregular.

You may want to look at some relevant references on the importance of the subject:

  • AHA + CFD + NATO = STEMI « SCIENCE LIFE – “Time is muscle”, cardiologists say. When someone has a heart attack, they don’t have much time. The longer blood flow through a coronary artery is blocked, the more heart muscle dies, and delays can mean permanent heart damage…This is exactly why people need a sound knowledge on ECG interpretation and why services need to be provided in the community to facilitate them at a primary care facility.
