Ekg Analysis
EKG Rhythm Interpretation
How to Analyze a Rhythm
All MIHS hospital nursing staff must complete an EKG test with a score of at least 80% upon hire. All hospital RNs are tested annually. This includes recognizing the rhythms, measuring the intervals, and knowing the appropriate treatment/algorithm according to American Heart Association. This is basic ACLS/PALS information, nothing new. In addition to this study packet, there are multiple websites that can be accessed on the internet from which to study. These can be found with a google search for EKG strips.

Lead Placement
Each lead is made up of a negative (-) and a positive (+) electrode. The electrodes sense both the magnitude and direction …show more content…
The QT interval is measured from the beginning of the QRS complex to the end of the T wave. A prolonged QT is associated with a high incidence of sudden death.
R wave is the first positive deflection of the QRS complex.
S wave is the first wave after the R wave that dips below the baseline (isoelectric line).
ST segment is located between the QRS complex and the T wave. The ST segment shows early repolarization of the ventricles. The STsegment usually lies along the EKG baseline. The heart does not have any electrical activity during this time. The ST segment begins at the J point and stops at the beginning of the T wave. ST deviation is a sign of myocardial ischemia, myocardial infarction and /or cardiac disease. ST changes (elevations or depressions) are suggestive of current events as in now.
J point is the end of the S wave where the S wave begins to flatten out.
T wave represents the repolarization of the ventricle. The T wave is normally asymmetrical and is usually larger than the P wave. The T wave is upright in lead II. As heart rates increase the P wave and the T wave can share the same space on an EKG. Abnormally shaped T waves can show acute episodes of cardiac ischemia, electrolyte imbalances, and the use of cardiac …show more content…
The U wave most often is in the same direction of the T wave with less amplitude. Abnormal U waves are associated with conditions such as hypokalemia, diabetes, ventricular hypertrophy, and cardiomyopathy.
Heart Rate and Pulse Rate
Heart rate is the number of QRS complexes present in a minute.
Pulse rate is the rate of perfusion of blood to the tissue
Heart rate is not always the same as pulse rate
Calculating Heart Rate
Six Second Count, multiplying the number of QRS complexes found over six seconds by a factor of 10 to get the QRS complexes found in a minute.
