Occupational lung disease electrocardiogram
Introduction
Overview
Overview
There are no ECG findings associated with occupational lung disease. However, chronic lung disease may be complicated by cor pulmonale. Findings on an ECG suggestive of cor pulmonale include, right axis deviation, R/S amplitude ratio in V1 greater than 1, R/S amplitude ratio in V6 less than 1, peaked P waves (P pulmonale in leads 2, 3, and aVF), S 1 Q 3 T 3 pattern and incomplete (or complete) right bundle branch block, and possibly, a low voltage QRS complex.
Electrocardiogram
Electrocardiogram
- There are no ECG findings associated with occupational lung disease.[1]
- However, an ECG may be helpful in the diagnosis of cor pulmonale, a possible complication of chronic lung disease. Findings on an ECG suggestive of cor pulmonale include:
- Right axis deviation
- R/S amplitude ratio in V1 greater than 1
- R/S amplitude ratio in V6 less than 1
- P pulmonale in leads 2, 3, and aVF
- S 1 Q 3 T 3 pattern and incomplete (or complete) right bundle branch block
- Low voltage QRS complex
- Found with hyperinflated lungs in COPD
