Ventricular Arrhythmias Worksheets
These worksheets are for self-study only. Answers will not be evaluated. Instructions and examples Instructions for Chapter 8 Worksheets For each arrhythmia, examine the whole strip and determine an atrial and ventricular rate. The P wave samples are not long enough to confirm the underlying rhythm is sinus or to be sure of the underlying […]

Axis: The Science of Direction Worksheet
These worksheets are for self-study only. Answers will not be evaluated. Instructions and examples Instructions for Chapter 6 Worksheets Complete basic measurements. Describe or calculate the P direction in the frontal plane as inferior or superior, leftward, or rightward. Diagnose the P direction as normal if it is inferior and leftward.

Axis: The Science of Direction Case Studies
Case 1: How leads determine direction Tap the arrow to view the case.How lead I separates left from right For this example, let’s visualize ventricular electrical systole, which is represented by the QRS. To determine and visualize whether the QRS is pointing, right or left, as well as up or down, first examine lead I. […]
