ECG interpretation artefact clinical guidance 12 lead ECG

ECG impression:
  • Rhythm: Regular sinus rhythm with a P wave before each QRS.
  • Rate: About 89 bpm.
  • Axis: Normal QRS axis, approximately +57°.
  • Intervals: PR 140 ms, QRS 70 ms, QTc about 426 ms. All are within usual normal limits.
  • QRS/ST-T: Narrow QRS complexes. No clear bundle-branch block, acute ST-segment elevation, significant ST depression, or convincing acute ischemic T-wave changes visible.
  • Other: There is mild baseline/muscle artifact. R-wave progression is relatively late, with predominantly negative complexes through V1-V3 and transition around V4. In isolation this can reflect normal variation or precordial lead positioning, rather than infarction.
Overall: This appears to be a normal sinus rhythm ECG without obvious acute ischemic changes on this photograph.
A photo cannot replace review of the original tracing in clinical context. If this was obtained for chest pain, breathlessness, fainting, sweating, or ongoing palpitations, seek urgent in-person assessment even if the ECG appears non-acute.
