Your ECG Report — Detailed Explanation

1. Supraventricular Tachycardia (SVT)
2. LVH (2) — Left Ventricular Hypertrophy
3. Incomplete Left Bundle Branch Block (ILBBB)
4. Long QTc
5. Unspecified ST-T Abnormality

What Each Finding Means

1. Supraventricular Tachycardia (SVT) — Heart Rate 140 bpm ⚠️

• This means the heart is beating too fast — 140 beats per minute (normal is 60–100).
• SVT means the fast rhythm is coming from above the ventricles (the upper heart chambers), not from the ventricles themselves — this is generally less dangerous than ventricular tachycardia.
• This is the most important finding here. A resting heart rate of 140 bpm is NOT normal.
• Causes include: anxiety, dehydration, fever, thyroid problems, anemia, stimulants, or a primary heart rhythm problem.

2. Long QTc — 479 ms ⚠️

• The QTc (corrected QT interval) is 479 ms, which is prolonged (normal is <440 ms in men, <460 ms in women).
• A long QT can increase the risk of a dangerous arrhythmia called Torsades de Pointes.
• However, when the heart rate is very fast (like 140 bpm here), QTc measurements are less reliable and may appear falsely prolonged.
• This needs to be rechecked after the heart rate returns to normal.

3. Incomplete Left Bundle Branch Block (ILBBB) — Mild Finding

• The heart's electrical signal has a slight delay going down the left side.
• "Incomplete" means it is a partial block — the QRS is 109 ms, just below the 120 ms threshold for a complete block.
• This can be a normal variant or seen with slightly enlarged heart muscle (LVH).

4. LVH (Left Ventricular Hypertrophy) — Possible Finding

• The machine flagged possible thickening of the left heart muscle.
• This is a machine interpretation and needs echocardiogram (heart ultrasound) to confirm.
• It can be caused by high blood pressure, but your doctor says your BP is LOW, so this may be a false positive from the ECG machine.

5. Unspecified ST-T Abnormality — Non-Specific

• Minor changes in the ST and T waves.
• These can be caused by the fast heart rate itself (rate-related changes) and may resolve completely once the heart rate comes down.

The Critical Point Your Doctor May Have Missed

The ECG is NOT normal. The heart rate of 140 bpm at rest is the main concern.

What You Should Do

1. Go back to the doctor and specifically ask about the heart rate of 140 bpm — this cannot be dismissed as "normal."
2. Ask if your thyroid hormones (TSH, T3, T4) have been checked — hyperthyroidism is a common cause of SVT + fast heart rate.
3. Ask for a repeat ECG when you are not having symptoms, and when the heart rate is normal.
4. Ask your doctor if an echocardiogram (Echo) is needed to check heart structure (LVH, function).
5. If you experience palpitations, dizziness, fainting, or chest pain — go to emergency immediately.
