Routine and exercise electrocardiography in aircrew; technique, interpretation, and recommendations

Area of Science:

• Aviation Medicine
• Cardiology
• Aerospace Physiology

Background:

• Current Civil Aviation Authority (CAA) guidelines mandate electrocardiographic surveillance for aviators.
• Ensuring accurate electrocardiogram (ECG) recordings is crucial for effective cardiac assessment in flight personnel.

Purpose of the Study:

• To outline current CAA requirements for aviator electrocardiographic surveillance.
• To provide guidance on the appropriate use and interpretation of exercise electrocardiograms in aviation.
• To emphasize the importance of standardized techniques and quality control in cardiac evaluations for pilots.

Main Methods:

• Review of current Civil Aviation Authority (CAA) regulations regarding electrocardiographic surveillance for flyers.
• Analysis of the utility and limitations of routine versus selective exercise electrocardiography.
• Discussion of probability analysis for interpreting exercise test results.

Main Results:

• Routine exercise electrocardiograms are not advised for all flyers, with potential exceptions for older commercial pilots.
• Exercise tests are valuable for equivocal cardiac symptoms or repolarization changes.
• Interpretation of exercise tests requires a probabilistic approach, avoiding simplistic 'positive' or 'negative' classifications.

Conclusions:

• Standardized, detailed, and approved methods are essential for exercise testing in pilots.
• Careful attention to recording techniques and equipment standards is paramount for electrocardiographic surveillance.
• The application of exercise electrocardiograms should be judicious and based on rigorous interpretation methods.
