ECG Interpretation

Patient: Male, Age 38 | ID: 20260731230810 | Name: Thirupathi Settings: Speed 25 mm/s | Filter 0.5-35 Hz, AC 50 Hz | Gain 10 mm/mV Organization: Health Haven

Technical Quality

There is significant baseline wander and muscle tremor artifact visible across several leads (I, II, III, aVR, V1), which slightly limits interpretation. The overall tracing is still interpretable.

Systematic Interpretation

ParameterFinding
Heart Rate~74 bpm (within normal range)
RhythmRegular sinus rhythm
P wavesPresent and upright in inferior leads; appear normal in morphology
PR intervalAppears within normal limits (~160-180 ms)
QRS durationAppears narrow (~80-100 ms)
QRS axisNormal axis

Lead-by-Lead Analysis

Limb Leads (Image 2 - I, II, III, aVR, aVL, aVF):
  • Lead I: Low amplitude with significant artifact; QRS appears normally oriented
  • Lead II: Sinus P waves visible; normal QRS morphology
  • Lead III: Some baseline artifact
  • aVR: Expected negative deflection
  • aVL: Small QRS complexes
  • aVF: Upright QRS - consistent with normal inferior axis
Precordial Leads (Image 1 - V1 to V6):
  • V1: rS pattern - normal for right precordial lead; no dominant R
  • V2: Small r wave, relatively deep S - suggesting poor R wave progression or normal variant
  • V3: Transitional zone; r wave beginning to increase
  • V4: R wave becoming dominant - transition zone appears around V3-V4
  • V5: Taller R waves; no significant ST changes visible
  • V6: Upright QRS with normal morphology

Key Observations

  1. ST segments: No definitive ST elevation or depression is seen across the precordial leads. Baseline artifact makes assessment in some limb leads difficult.
  2. T waves: Appear upright in lateral precordial leads (V4-V6), which is normal. T wave morphology in V1-V2 appears to have some flattening (partly due to artifact).
  3. Q waves: No pathological Q waves identified.
  4. QTc: Machine-recorded values are partially obscured but appear within normal range.
  5. R wave progression: Normal R wave progression from V1 to V6.

Impression

Normal sinus rhythm at ~74 bpm with no acute ischemic changes identified. No significant ST-T abnormalities. Normal R wave progression. Significant baseline artifact in limb leads reduces certainty for limb lead assessment.
Differential considerations given the artifact:
  • The tremor artifact, especially in leads I and III, should prompt ensuring good electrode contact if the ECG needs to be repeated
  • At age 38 with a normal-looking tracing, no acute pathology is evident on this recording
