Image 15: Standard Limb Leads ECG Augmented Leads Using the same placement of three-electrode pads and a little fancy math, we can get different views of the electrical activity in the heart. Known as augmented limb leads, unipolar limb leads, or just unipolar leads, an electrocardiogram can ...
The EKG rhythm will appear not present with heart rate that is absent. The P wave features: absent. Observe that the PR interval is absent. The QRS complex will typically be absent. confirm with multiple leads. Atrial Fibrillation The EKG rhythm will appear irregular with heart rate that is...
Ischemia to the heart can cause angina and if present long enough, infarction Precordial leads are chest leads The right leg electrode shows no cardiac information, and serves as a ground electrode A muscle tremor would look like a fuzzy irregular baseline on an EKG A broken cable wire would...

An EKG is a graph (thusly named an electrocardiograph) tracing the strength and direction of this electrical signal. Leads equipped with conductive goo are placed on different parts of the body allowing a view of the heart from different angles. If the electrical activity of the heart at any ...
