Left Bundle Branch Block Worksheets
These worksheets are for self-study only. Answers will not be evaluated. Instructions and examples Instructions for Chapter 12 Worksheets Complete basic measurements. If the QRS is ≥ 0.12 sec, diagnose BBB. Then visualize the extra piece at the end of the QRS in the frontal plane as right or left, and in the horizontal plane […]
Left Bundle Branch Block Case Studies
Case 1: Left bundle branch block Tap the arrow to view the case.This is an example of LBBB. It meets the two criteria for diagnosis. First, the QRS interval is 0.12 seconds or more. This means the ventricles were not depolarized simultaneously, but sequentially. Since the ventricles are out of sequence, inspection of the last […]
12. Left Bundle Branch Block
In this material Self-study learning goals Define and Identify the following: Normal QRS interval. Normal QRS direction. Define the two EKG criteria for LBBB. Define the pathophysiology of left bundle branch block. Describe how LBBB causes desynchronization. Describe how desynchronization hurts LV function. Describe resynchronization. Describe the differential diagnosis of etiologies LBBB. Normal physiology of […]
Right Bundle Branch Block Worksheets
These worksheets are for self-study only. Answers will not be evaluated. Instructions and examples Instructions for Chapter 11 Worksheets Complete basic measurements. If the QRS is ≥ 0.12 sec, diagnose BBB. Then visualize the extra piece at the end of the QRS in the frontal plane as right or left, and in the horizontal plane […]
Right Bundle Branch Block Case Studies
Case 1: Right bundle branch block Tap the arrow to view the case.This is an example of the simple case of RBBB. It meets the two criteria for diagnosis. First, the QRS interval is 0.12 seconds or more. This means the ventricles were not depolarized simultaneously, but in sequence. Since the ventricles are out of […]
11. Right Bundle Branch Block
In this material Self-study learning goals Electrocardiograms Define and identify the following: Normal QRS interval. Normal QRS direction. Define the two EKG criteria for RBBB. Recognize RBBB in the presence of: No other disease. Hemiblock. Myocardial infarction. Describe the expected ST changes in RBBB. Clinically-based critical interpretation Define the pathophysiology of RBBB. Describe the […]
Hemiblock Worksheets
These worksheets are for self-study only. Answers will not be evaluated. Instructions and examples Instructions for Chapter 10 Worksheets Complete basic measurements. Describe (or calculate!) the QRS direction in the frontal plane as inferior and left, superior, or rightward. Clinically diagnose LAHB if the QRS direction is superior. Diagnose LPHB if the QRS direction is […]
Hemiblock Case Studies
Case 1: Left anterior hemiblock, step-by-step example Tap the arrow to view the case. Lead I is positive, so the QRS direction is to the patient’s left side (somewhere between –90 and +90). Lead AVF is negative, so the QRS direction is upward (this narrows it down to between 0 and –90). Lead II is […]
