Table 4 ECG changes in pilots and non-pilot aircrew over a longitudinal period of 13.4 years. HR = heart rate; bpm = beats per minute; n = number; * = This myocardial infarction was already known from the patient’s history; the proband would have been disqualified regardless of his ECG findings
From: Electrocardiographic abnormalities in medically screened German military aircrew
ECG abnormality | N | Disqualification because of ECG finding |
|---|---|---|
Intermittent ventricular pre-excitation, known from medical history | 1 | No |
Single episode of atrial fibrillation with tachyarrhythmia | 1 | Yes |
QRS voltage criteria for left ventricular hypertrophy | 2 | No |
Escape beats with left bundle branch block morphology (one single episode) | 1 | No |
Previous myocardial infarction | 1 | No* |
Complete right bundle branch block (no progression from incomplete block) | 1 | No |
Loss of R waves in precordial leads | 1 | Yes |
Sinus bradycardia (< 40 bpm) | 17 | No |
Negative T waves | 3 | No |
