An electrocardiogram is a picture of the electrical conduction of the heart. By examining changes from normal on the ECG, clinicians can identify a multitude of cardiac disease processes.

The Learn the Heart ECG Basics module contains detailed articles ... Don’t forget to learn what a non-specific interventricular conduction delay looks like, as well. This is the fun part of ...

left axis deviation and conduction delays and findings suggestive or diagnostic of primary electrical diseases such as long QT syndrome and Wolff-Parkinson-White syndrome. The evaluation of abnormal ...

The resting electrocardiogram (ECG) furnishes essential information for the diagnosis, management, and prognostic evaluation of patients with congestive heart failure (CHF). Almost any ECG ...

Multiple other ECG traits have also emerged as potential predictors of stroke, namely cardiac electrical/structural remodeling – Q wave, QRS/QT duration, bundle blocks, P wave duration/amplitude ...

This represents a greater disturbance of AV nodal conduction than first-degree AV block ... particular care should be devoted to the auscultation of a fixed splitting of the second heart sound because ...

The CCS generates and propagates electrical impulses critical for the heart's rhythmic contractions ... as confirmed by ECG recordings showing no conduction delays. Non-regenerative P7 hearts ...

However, this short-term regulation did not explain why the heart conduction system generally slowed down at night ... Mice exhibit a well-documented circadian rhythm and ECG parameters comparable to ...
