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: Characterized by Atrial rate usually faster than ventricular rate (usually slow)
Rhythm: Regular (atrial) and irregular (ventricular)
P Wave:Normal form, but more P waves than QRS complexes
PR Interval: Normal or prolonged
QRS: Normal or wide
A constant P-R interval with missing QRS complexes. Occurring in a specific pattern in a ratio with the P waves.
Second degree Heart Block Mobitz II is characterized by intermittently non-conducted P waves which are not preceded by PR prolongation and are not followed by PR shortening. Mobitz II is usually caused by conduction failure/delay of the His-Purkinje system. In three out of four cases, this conduction block is located distal to the Bundle of His, creating wide QRS complexes. In the other 25% of cases, the block is located within the Bundle of His, producing narrower QRS complexes.
