ECG Interpretation

Practise interpreting long-term ECGs – and spotting when the automatic algorithm gets it wrong. Choose a case, give your interpretation, and get a reasoned review from JARLE.

Automatic arrhythmia detection

ECG247 detects all common heart rhythm disturbances

Rhythm disturbances are detected and colour-coded automatically, so the most urgent findings are always shown first.

Always verify. All automatically detected rhythm disturbances must be verified by a doctor before starting treatment.

Priority order: Red› Orange› Yellow› Green
Red Highest priority
  • Ventricular tachycardia ≥30 s
  • Pause ≥4 s
  • Heart rate <30/min (≥30 s)
  • Supraventricular tachycardia ≥30 s
Orange High priority
  • Atrial fibrillation ≥30 s
  • Atrial flutter ≥30 s
Yellow Moderate priority
  • Ventricular tachycardia ≥4 beats and <30 s
  • Supraventricular tachycardia 15–30 s
  • Heart rate >180/min (≥5 min)
Green Low priority
  • Ventricular ectopic beats
  • Supraventricular ectopic beats
  • Sinus arrhythmia / irregular beats
  • Heart rate >180/min (<5 min)
  • Periodic recordings

Recording length

ECG files are recorded in standard one-minute intervals. During ongoing arrhythmias the recording is extended to four minutes, and continuous arrhythmias are stored in successive four-minute files.

Manual recordings – coded black

Recordings started manually are coded black. If an arrhythmia is detected, the recording is shown in the relevant arrhythmia category. Manual recordings should always be interpreted.
