ECG Interpretation

• Date: 22-04-2026, Time: 10:23:22
• Paper speed: 25 mm/s
• Gain: 10 mm/mV
• Heart rate: 79 bpm (shown as ♥79)
• Patient: Шугунова Х.Т.Т., Age 26

Rhythm & Rate

• Heart rate: 79 bpm — normal
• Rhythm: Regular sinus rhythm (P waves are visible and upright in I, II, and aVF)
• P wave axis: Normal (upright in II, inverted in aVR) — confirms sinus origin

Intervals

• PR interval: Appears normal (~160–180 ms) — no first-degree AV block
• QRS duration: Appears narrow (<120 ms) — no bundle branch block
• QT/QTc: Appears within normal limits for rate of 79 bpm

Axis

• Lead I: positive QRS
• Lead aVF: appears positive or isoelectric
• Electrical axis: Normal (approximately 0° to +60°)

P Waves

• Upright and normal morphology in leads I, II, aVF
• Inverted in aVR — as expected
• No signs of left or right atrial enlargement

QRS Complex

• No pathological Q waves identified in inferior (II, III, aVF) or lateral (I, aVL, V4–V6) leads
• R wave progression in precordial leads appears appropriate (R waves increasing V1→V5/V6)
• No left ventricular hypertrophy (LVH) criteria evident

ST Segment & T Waves

• No significant ST elevation or depression in any lead
• T waves appear upright in lateral and inferior leads
• T wave in V1–V2 may be slightly flat/biphasic — a common normal variant
• No acute ischemic changes identified

Overall Interpretation

Normal sinus rhythm at 79 bpm. No acute ST-T changes. No conduction abnormality. Normal ECG for a 26-year-old patient.

Clinical Notes

• This appears to be a routine ECG in a young (26-year-old) patient
• No evidence of:
  • Acute myocardial ischemia or infarction
  • Bundle branch block
  • Pre-excitation (no delta waves)
  • Long QT syndrome
  • Arrhythmia
• Clinical correlation is always recommended — if the patient has symptoms (chest pain, palpitations, syncope), targeted repeat evaluation may be warranted

ECG Interpretation

• ID: 40001066
• Date: 21-04-2026, Time: 04:20:38
• Paper speed: 25 mm/s
• Gain: 10 mm/mV
• Heart rate: 84 bpm
• Algorithm: SEMIP V1.7

Rhythm & Rate

• Heart rate: 84 bpm — normal
• Rhythm: Regular sinus rhythm — P waves visible, consistent morphology, regular R-R intervals
• P waves upright in II, aVF → sinus origin confirmed

Intervals

• PR interval: Appears normal (~160–200 ms)
• QRS duration: Appears narrow — no bundle branch block pattern
• QT interval: Appears within normal limits for HR 84 bpm

Electrical Axis

• QRS positive in I and aVF → Normal axis (~+60°)

Key Findings by Region

⚠️ Precordial Leads (V1–V4) — Most Notable Finding

• V1–V3: Deep, wide QS or rS pattern — poor R wave progression or absent R waves in early precordial leads
• V1: Predominantly negative (QS pattern)
• V2–V3: Very deep S waves / QS morphology
• V4: QS or very small r with deep S
• This pattern of absent R wave progression V1–V4 raises concern for:
  • Anterior wall myocardial infarction (AMI) — either acute or old/established
  • The deep negative deflections in V1–V3 are significant

ST Segments

• V1–V3: Possible ST elevation — the baseline appears elevated above the isoelectric line in V1–V3, which combined with QS morphology is consistent with acute anterior STEMI pattern
• V4–V6: ST segments appear to return toward baseline; T waves may be upright
• Inferior leads (II, III, aVF): No clear ST elevation; morphology appears relatively preserved

Lateral Leads (I, aVL)

• QRS appears small; possible reciprocal changes or low voltage
• aVL: small complex, no obvious ST elevation

🔴 Summary / Impression

⚠️ ABNORMAL ECG — Findings consistent with Anterior Myocardial Infarction

1. Acute anterior STEMI (LAD territory) — ST elevation + QS in V1–V3 → urgent concern
2. Old anterior MI with persistent ST elevation (LV aneurysm pattern)
3. LBBB — less likely given narrow QRS
4. Normal variant — less likely given the degree of changes

🚨 Clinical Recommendation

• Serial ECGs and continuous monitoring
• Troponin I/T (stat and repeat at 3h)
• Clinical correlation: chest pain, dyspnea, diaphoresis?
• If acute STEMI confirmed → activate catheterization lab immediately
• Cardiology consultation urgent
