Determining Electrical Axis
15:20 min ©1987 Advanced
Level CE 5 hours $199
Describes how to determine the electrical axis of the heart
using the 12-lead ECG. Illustrates six frontal plane lead positions and charges
using original graphics. Identifies vector direction, based on QRS deflection,
and presents a method to calculate its net deflection. Demonstrates the
step-by-step process to determine electrical axis using actual ECGs and
discusses causes of axis deviation. Emphasizes patient assessment, accurate
documentation and comparison of ECG findings in the evaluation of axis
deviation.

Intraventricular Conduction Disturbances
26:11 min ©1987 Advanced
Levels CE 8 hours $199
Identifies ECG changes associated with intraventricular
conduction disturbances. Discusses the normal process of synchronous ventricular
activation and anatomic differences of bundle branches, Emphasizes the clinical
significance of right and left bundle branch blocks. Demonstrates detection of
the onset of intraventricular conduction disturbances and determining the area
involved through the use of actual ECGs.

Ventricular Ectopy vs. Aberrancy
16:38 ©1987 Advanced
Level CE 8 hours $199
Assesses the cardiac waveform to distinguish clinically
insignificant changes from those warranting immediate intervention. Focuses on
differentiation between ventricular ectopy and aberrancy through authentic
examples of rhythm strips and 12-lead ECGs. Describes action potential phases of
the cardiac ventricular cells and explains the difference between normal cardiac
impulse conduction and ventricular ectopic impulse conduction.
Compares right bundle branch block aberration to left
ventricular ectopy and left bundle branch block aberration to right ventricular
ectopy.
