Interpretation Of Ecg Strips

How ecg leads work. The standard ecg is in 12 leads includes three limb leads i ii and iii three augmented limb leads avr avl and avf and six chest leads v 1 v 2 v 3 v 4 v 5 and v 6.

When you visit for ecg test there are a lot of leads applied to your body surface.

Interpretation of ecg strips. As a result you need to apply a different method. To better distinguish specific waves and dips in the ecg strip we assign each wave and dip a letter. Failure to perform a systematic interpretation of the ecg may be detrimental.

Count the number of complexes on the rhythm strip each rhythm strip is typically 10 seconds long. To briefly summarize the components of a normal ekg strip it consist of components which indicate electrical events during one heart beat. The ecg must always be interpreted systematically.

These leads help to record your electrical activity in 12 different views of the heart. It indicates that the atria are contracting pumping blood into the ventricles. If a patient s heart rhythm is irregular the first method of heart rate calculation doesn t work as the r r interval differs significantly throughout the ecg.

We decipher basic observations by reading the following components of the ecg strip. You aren t the only one that s a bit terrified of ekgs. For many nursing students and new nurses ekg interpretation can be intimidating to say the least.

Ekgs can be used to diagnose heart attacks heart problems including electrical malfunctioning and other heart problems. First the standard 12 lead ecg is a 10 second strip. Let s just clear that up right away.

P wave is the first short upward movement of the ecg tracing. The reader will gradually notice that ecg interpretation is markedly facilitated by using an algorithm as it minimizes the risk of missing important abnormalities and also speeds up the interpretation. The bottom one or two lines will be a full rhythm strip of a specific.

These waveforms are labeled p q r s t and u. The ekg is a printed capture of a brief moment in time. Interpret ekgs strips like a boss.

An ekg is a representation of the electrical activity of the heart muscle as it changes with time usually printed on paper for easier analysis. Now if we go back to the ecg tracing each wave and dip represents a piece of the heart. This is referred to as depolarization or the squeezing effect.

The interpretation algorithm presented below is easy to follow and it can be carried out by anyone. When looking at a 12 lead ecg a few logistics must be understood. This represents a contraction of the atria.
