ECG Training Modules 2022

Our new ECG modules provide in-depth training in ECG interpretation basics, rhythm analysis and abnormality recognition. Modules include lessons, interactive exercises and a course quiz.

ECG Training Modules

ECG Interpretation Practice Coach

The ECG 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

ECG Abnormality Examples

Our ECG Examples provides information on reading ECG 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: Normal to slow
Rhythm: Irregular due to pause
P Wave:Normal
PR Interval: Normal (0.12-0.20 sec)
QRS: Normal (0.06-0.10 sec)
Sudden absence of electrical activity initiated by the SA node. This results in a pause in the electrical activity seen on the tracing. The sinus pause rhythm typically will demonstrate constant R to R intervals prior to and following the pause.
Sinus arrest is a pause in the generation of electrical impulses by the SA node. The sinus arrest pause is usually followed by a new sinus node beat or by an AV node escape beat. If no pacemaker begins activity, then the condition becomes cardiac arrest. If an ectopic site (e.g. AV junction or ventricles) takes over, the beat will likely be slower. Refer to sinoatrial block for information on a similar EKG.
