Is it normal

Reading File
No, this ECG is NOT normal. The machine itself flags it as "Moderately Abnormal ECG." Key concerns are low-voltage QRS complexes and a prolonged QT interval. These findings together warrant physician review and likely further workup.

Here is a detailed breakdown of this ECG:
ECG Analysis
Patient & Machine Data
- Date/Time: 2026-07-29, 09:16:42
- Hospital: V Care Mediscon
- Sex: Female | Age: 0 years (likely a data entry error - field left blank)
- Heart Rate: 73 bpm
- PR/RR Intervals: 118/822 ms
- QRS Duration: 90 ms
- QT/QTc: 422/470 ms
- P-R-T Axes: 47 / 59 / 57
- SV1/RV5/R+S: 0.38/0, 18/0.48 mV
Machine Interpretation (Auto-Analysis)
The machine has flagged this ECG as:
- Normal Sinus Rhythm
- Low Voltage QRS
- Normal Axis
- Prolonged QT - QTc is 470 ms (normal upper limit is ~440 ms in women, ~450-460 ms is borderline)
- "Axis and MI may be incorrect due to low voltage" - the machine itself acknowledges its analysis may be unreliable
- Moderately Abnormal ECG - to be finally confirmed by physician
Key Abnormalities Explained
1. Low Voltage QRS
- QRS complexes appear small across leads
- RV5 reads as 0 mV, which is abnormal (normally >0.5 mV)
- Causes of low voltage include:
- Pericardial effusion (fluid around heart dampens signal)
- Obesity or large body habitus
- Hypothyroidism
- COPD/emphysema (hyperinflated lungs)
- Cardiomyopathy
- Poor electrode contact (technical issue)
2. Prolonged QTc (470 ms)
- Normal QTc: up to ~440 ms (women), ~450 ms (men)
- QTc of 470 ms is prolonged
- This is significant because a long QT increases the risk of a dangerous arrhythmia called Torsades de Pointes
- Causes include:
- Electrolyte imbalances (low potassium, magnesium, calcium)
- Medications (antiarrhythmics, antibiotics, antidepressants)
- Congenital long QT syndrome
- Heart disease
Bottom Line
This is not a normal ECG. The two main findings - low voltage and prolonged QT - both require follow-up:
| Finding | Clinical Action Needed |
|---|---|
| Low voltage QRS | Echo to rule out pericardial effusion; thyroid function tests; chest X-ray |
| QTc 470 ms | Check electrolytes (K+, Mg2+, Ca2+); review all medications for QT-prolonging drugs; consider cardiology referral |
Important: The machine note says findings must be "finally confirmed by physician." This ECG should be reviewed by a doctor, who will correlate it with the patient's symptoms, medications, and other test results. Do not ignore this - please show it to your doctor.
