ECG Measurements

Machine Interpretation

1. SINUS RHYTHM WITH SINUS ARRHYTHMIA
2. NONSPECIFIC ST & T-WAVE ABNORMALITY
3. BORDERLINE ECG

Technical Settings

• Speed: 25 mm/s
• Gain: 10 mm/mV
• Filter: 0.05 - 40 Hz

Brief Clinical Notes

• Sinus arrhythmia in a 22-year-old male is a normal, common finding - it simply means the heart rate varies slightly with breathing (faster on inspiration, slower on expiration).
• PR interval (167 ms) is within normal limits (120-200 ms).
• QRS duration (89 ms) is normal (< 100 ms).
• QTc values are borderline - QTcB of 412 ms is within acceptable range for males (normal < 440 ms), and QTcF of 392 ms is reassuringly normal.
• The nonspecific ST & T-wave abnormality flag is a machine-generated finding that requires a physician to review visually. It can be benign (positional, early repolarization, electrolyte variation) or occasionally clinically significant.
• "Borderline ECG" is a machine classification meaning the tracing is not clearly normal nor clearly abnormal - a cardiologist or physician should review it in clinical context.
