ECG Analysis — Renu Aagarwal | 22.04.2026 | 00:09:45

Machine-Reported Parameters (from the printout)

Machine Interpretation (printed on ECG)

1. Sinus tachycardia
2. Leftward electrical axis
3. Nonspecific T abnormality
4. Borderline ECG
5. Unconfirmed report

Clinical Interpretation

1. Sinus Tachycardia (HR 109 bpm)

• Upright P waves in lead II, regular rhythm, rate >100 bpm
• The causes are broad and require clinical correlation:
  • Physiological: pain, anxiety, fever, exercise, dehydration
  • Cardiac: heart failure, pericarditis, myocarditis
  • Non-cardiac: anemia, thyrotoxicosis, pulmonary embolism, sepsis, hypovolemia

2. Leftward Electrical Axis (QRS axis ~12°)

• Still within normal range technically (−30° to +90°), though the machine flags it as "leftward"
• If axis were more negative (<−30°), it would suggest Left Anterior Fascicular Block (LAFB)
• Causes of leftward shift: LV hypertrophy, inferior MI, LAFB, obesity, pregnancy

3. Nonspecific T-Wave Abnormality

• T-wave flattening or subtle inversions, not meeting criteria for ischemia
• Seen with: electrolyte imbalances (hypokalemia, hypomagnesemia), digoxin effect, myocardial strain, pericarditis, cardiomyopathy, or simply hyperventilation/anxiety

4. QTcB = 432 ms

• Borderline prolonged (normal <440 ms in females — this patient is female)
• Warrants monitoring, especially if on QT-prolonging medications

Differential Diagnoses to Consider

Recommended Next Steps

1. Clinical history — symptoms (chest pain, dyspnea, palpitations, fever, weight loss)
2. Vitals — BP, SpO₂, temperature
3. Blood tests — CBC, electrolytes (K⁺, Mg²⁺), TFTs, troponin, D-dimer if PE suspected
4. Repeat ECG at rest — if initially taken during distress
5. Echocardiography — if structural cause suspected
