EKG Interpretation Practice Coach

The EKG coach breaks down interpretation into five analysis steps followed by classification of the ECG strip. Scoring based upon both analysis and interpretation are available..

ECG Rhythm Interpretation Coach

EKG Abnormality Examples

Our EKG Examples provides information on reading EKG strips with over forty different abnormal EKG examples. For each arrhythmia, there are EKG strip examples and descriptive text. We also provide an annotated tracing with a summary of the key features and values.

Explanation

Rate: The underlying rate
Rhythm: Irregular but with progressively longer PR interval lengthening
P Wave:Normal
PR Interval: Progressively longer until a QRS complex is missed, then cycle repeats
QRS: Normal (0.06-0.10 sec)
A prolonging P-R interval from one cardiac complex to the next, until it reaches a point where the QRS complex is non-conducted (blocked or more simply missing). Then the pattern starts over again.
Second degree Heart Block Type I Wenckebach is a condition where the atrioventricular node conducts each successive impulse earlier and earlier. The PQ interval prolongs from beat to beat up until a drop-out of one QRS complex. The following impulse will then be conducted normally and the cycle to begin again. Thus, the presence of second-degree AV block is diagnosed when one or more (but not all) of the atrial impulses fail to conduct to the ventricles.
