Table 2.

Categories of screening results as reported to general practices in the safer trial

Diagnosis Definition
1. AF ≥30 s AF is observed for a continuous period of 30 s. Sufficient readable beats (ie, disregarding poor quality sections of an ECG) show AF
2. Cannot exclude AF ≥30 s Indeterminate result—usually due to poor quality ECG traces
3. Other significant arrhythmia This may include, but is not limited to:

  • Second/third degree heart block

  • Ventricular tachycardia

  • Supraventricular tachycardia

  • Any other significant arrhythmia
4. No AF ≥30 s detected This will include, but is not limited to:

  • Sinus rhythm

  • AF <30 s

  • Bradycardia

  • Ectopic beats
5. Screening failure Unable to record any ECGs of sufficient quality for review

AF, atrial fibrillation.
