Here is a full interpretation of this ECG:
ECG Analysis — Patient: Fatema, Female, 46y | Recorded: 2026-04-19
Measured Parameters (from printout)
| Parameter | Value | Normal Range |
|---|---|---|
| Heart Rate | 102 bpm | 60–100 bpm |
| PR Interval | 199 ms | 120–200 ms |
| P Duration | 121 ms | <120 ms |
| QRS Duration | 94 ms | <120 ms |
| QT/QTc | 375/487 ms | QTc <440 ms (F) |
| P/QRS/T Axis | 65.6° / −33.8° / 42.1° | QRS: −30 to +90° |
Findings
1. Sinus Tachycardia (102 bpm)
- Regular rhythm with P waves preceding every QRS
- Rate just above the upper limit of normal (>100 bpm)
- Causes to consider: anxiety, pain, fever, anemia, thyrotoxicosis, heart failure, dehydration, medications
2. Left Axis Deviation (QRS axis −33.8°)
- Borderline/moderate left axis deviation (−30° to −90° range)
- The machine labels it "middling" (borderline)
- Differential: left anterior fascicular block (LAFB), LVH, inferior MI, COPD, hyperkalemia
3. Prolonged QTc (487 ms) ⚠️
- Significantly prolonged (normal <440 ms in females)
- This is clinically important — risk of Torsades de Pointes (TdP) and malignant arrhythmia
- Causes: electrolyte disturbances (↓K⁺, ↓Mg²⁺, ↓Ca²⁺), drugs (antiarrhythmics, antipsychotics, antibiotics), congenital long QT syndrome, cardiac disease
4. Abnormal T Waves in I, aVL, V6
- T wave abnormalities in lateral leads suggest lateral wall strain, ischemia, or LVH with repolarization changes
- Needs correlation with symptoms and prior ECGs
5. Borderline P Duration (121 ms)
- Slightly prolonged P wave may suggest left atrial enlargement or interatrial conduction delay
Machine Conclusions (confirmed)
Sinus mode Tachycardia | Middling Left axis deviation | I aVL V6 Abnormal T wave
Clinical Interpretation & Recommendations
Priority concern: QTc of 487 ms is prolonged and must be addressed.
- Check electrolytes — potassium, magnesium, calcium urgently
- Review medications — any QT-prolonging drugs? (antibiotics, antipsychotics, antiemetics, antifungals)
- Evaluate for cause of tachycardia — clinical history, vitals, thyroid function, CBC
- Echocardiogram — to assess for LVH, wall motion abnormalities (given lateral T wave changes and LAD)
- Correlate with symptoms — palpitations, chest pain, dyspnea, syncope?
- Avoid QT-prolonging medications until QTc normalizes
- Physician confirmation is required (as stated on the printout)
⚠️ This interpretation is for reference only and must be confirmed by the treating physician. The prolonged QTc (487 ms) in the setting of tachycardia warrants urgent clinical evaluation.
This pt has a complaint of shortness of breath and pain radiating in arm and back chest numbness tingling in left arm

⚠️ HIGH SUSPICION: Acute Coronary Syndrome (ACS) — Possible NSTEMI
This clinical picture is a medical emergency. Here is the full correlation:
Symptom-ECG Correlation
| Finding | Significance |
|---|---|
| Chest pain + back pain + left arm pain/numbness/tingling | Classic anginal radiation pattern — myocardial ischemia until proven otherwise |
| Shortness of breath | Common accompanying symptom of ACS, especially in women |
| Sinus tachycardia (102 bpm) | Sympathetic activation — body compensating for ischemia/pain |
| Abnormal T waves in I, aVL, V6 (lateral leads) | Strongly suggests lateral wall ischemia |
| Left axis deviation (−33.8°) | May indicate prior inferior MI or left anterior fascicular block from ischemic disease |
| Prolonged QTc (487 ms) | Can worsen with ischemia — risk of dangerous arrhythmia |
Why This Pattern Is Especially Concerning in Women
Women (as this patient is — 46F) frequently present with atypical ACS symptoms:
- Back pain, jaw pain, arm numbness, fatigue instead of classic crushing chest pain
- Higher rates of missed or delayed diagnosis
- NSTEMI is more common than STEMI in women
- Outcomes are worse when diagnosis is delayed — Tintinalli's Emergency Medicine; Rosen's Emergency Medicine
The combination of left arm tingling + chest pain + back pain + shortness of breath in a 46-year-old woman with lateral T wave abnormalities on ECG = ACS until proven otherwise.
Differential Diagnosis (to rule out)
- NSTEMI ← most likely given ECG + symptoms
- Unstable angina
- Aortic dissection (back pain — must consider, especially if BP differs between arms)
- Pulmonary embolism (dyspnea, tachycardia)
- Cervical radiculopathy (arm numbness/tingling — but less likely with chest/back pain together)
Immediate Management Protocol
🚨 Do RIGHT NOW:
- 12-lead ECG repeat — compare with this tracing, look for dynamic changes (evolving ST elevation/depression)
- Cardiac biomarkers — Troponin I or T (high-sensitivity), STAT; repeat in 3 hours
- IV access — two large-bore IVs
- Oxygen — if SpO₂ <94%
- Aspirin 325 mg — chew immediately (if no contraindication)
- Morphine or IV nitrates — for pain relief (caution: avoid nitrates if RV infarct suspected or BP low)
- Monitor continuously — given prolonged QTc and tachycardia, arrhythmia risk is real
🔬 Urgent Investigations:
- Troponin (serial), CK-MB
- CBC, BMP (electrolytes — check K⁺, Mg²⁺ given prolonged QTc)
- Chest X-ray (widened mediastinum → aortic dissection)
- If aortic dissection suspected: CT angiography chest STAT (back pain is a red flag)
- D-dimer if PE in differential
- Echocardiogram (wall motion abnormalities confirm ischemia)
💊 Anticoagulation & Antiplatelet (if ACS confirmed):
- Aspirin + P2Y12 inhibitor (clopidogrel or ticagrelor)
- Heparin (LMWH or UFH)
- Cardiology consult urgently for possible catheterization
⚠️ Critical Warning
Do NOT dismiss this as musculoskeletal or anxiety. The combination of:
- Left arm numbness + tingling
- Chest and back pain
- Shortness of breath
- Tachycardia
- Lateral T wave abnormalities on ECG
- Prolonged QTc
...in a middle-aged woman is an ACS presentation until cardiac biomarkers and imaging prove otherwise. This patient needs emergency cardiology evaluation immediately.
This analysis is for clinical reference only and must be confirmed by the treating physician.
What are the test and in rounded up
Tests Ordered (Handwritten Note)
The doctor has written the following tests, with a charge of ₹20/- circled:
| # | Abbreviation | Full Name |
|---|---|---|
| 1 | BP | Blood Pressure (measurement) |
| 2 | CBE | Complete Blood Examination (= CBC / Complete Blood Count) |
| 3 | TSH | Thyroid Stimulating Hormone |
| 4 | ECG | Electrocardiogram |
| 5 | RBS | Random Blood Sugar |
| 6 | HbA1c | Glycated Haemoglobin (3-month average blood sugar) |
| 7 | Urine Microalbumin | Urine Microalbuminuria test (early kidney damage marker) |
Why These Tests Make Sense for This Patient
Given the ECG findings + symptoms (chest pain, shortness of breath, left arm tingling):
| Test | Purpose |
|---|---|
| BP | Hypertension is a major cardiac risk factor; also rules out aortic dissection if bilateral BP difference |
| CBC | Check for anemia (can cause tachycardia + dyspnea), infection, or thrombocytopenia |
| TSH | Thyroid disease causes tachycardia, prolonged QTc, and can mimic cardiac symptoms |
| ECG | Already done — serial ECGs needed to detect dynamic ischemic changes |
| RBS | Diabetes is a major ACS risk factor; hyperglycemia common during cardiac events |
| HbA1c | Detects undiagnosed or poorly controlled diabetes |
| Urine Microalbumin | Screens for diabetic/hypertensive nephropathy — indicates end-organ damage |
⚠️ What's Missing (Given ACS Suspicion)
These critical tests are not on the list but are urgently needed:
- Troponin I/T (STAT + serial) — most important to rule in/out NSTEMI
- Serum Electrolytes (K⁺, Mg²⁺) — essential given prolonged QTc of 487 ms
- Chest X-ray — rule out dissection, pulmonary edema
- D-dimer / CT-PA — if pulmonary embolism is in differential
- Lipid profile — cardiac risk assessment
The treating physician should be alerted to add Troponin urgently given the clinical presentation.
