Interpretation:
Ectopic atrial rhythms can occur in the absence or presence of structural heart disease, and occur when the ectopic site rate is faster than the sinus rate. It may not reflect any underlying pathology and can occur with increased vagal tone, drug toxicity, and ischaemia.

- 78 bpm
- Regular QRS
- Preceded by abnormal P wave
- Right axis deviation
- PR - Normal (120ms)
- QRS - Normal (70ms)
- QT - 330ms (QTc Bazette 390 ms)
- Normal
Additional:
- P wave inverted leads II, III, aVF, V3-6
- Positive P wave lead aVR
- T inversion lead III
Interpretation:
- Ectopic atrial rhythm
- Low atrial focus - inverted P waves in inferior leads
- Normal pr interval favors atrial rather than junctional focus
- Right axis deviation
