The ECG report shows three automated conclusions with a note that physician confirmation is required. Here is what each finding means:
ECG Report Interpretation
Findings Reported
1. Sinus Mode Tachycardia
The heart is beating in a normal sinus rhythm (the electrical signal is coming from the sinoatrial node, which is correct), but the rate is too fast - typically defined as a heart rate above 100 beats per minute. Sinus tachycardia is usually a response to something else, not a primary heart problem. Common causes include:
- Fever, pain, or anxiety
- Dehydration or blood loss
- Anemia
- Hyperthyroidism
- Physical exertion
- Certain medications or stimulants
2. Cardiac Electric Axis Normal
The overall direction of the heart's electrical activity is within the normal range (roughly -30° to +90°). This is a reassuring finding - it means the heart's conduction system and ventricular muscle mass are not significantly shifted.
3. ST Depression - Mild High Lateral Myocardial Ischemia
This is the most clinically significant finding. ST depression on ECG suggests that part of the heart muscle may not be receiving enough blood flow (ischemia). "High lateral" refers to the territory supplied by the left circumflex artery or diagonal branches of the left anterior descending artery, seen in leads I and aVL (and sometimes V5-V6).
- ST depression can indicate demand ischemia (heart working too hard, as in tachycardia) or supply ischemia (blocked/narrowed artery)
- "Mild" suggests it is not severe or extensive
- This is NOT the same as a heart attack (which usually shows ST elevation), but it does warrant further evaluation
What This Combination Means Together
The tachycardia itself can cause ST depression - a fast heart rate increases oxygen demand and can produce transient ischemic changes, especially if there is underlying coronary artery disease. This means the ST changes may be secondary to the fast heart rate, or they may represent true ischemia that is also driving the fast rate.
Important Notes
- The report itself says "Report need physician confirm" - this is an automated machine interpretation and must be reviewed by a doctor before acting on it.
- If the person has chest pain, breathlessness, sweating, or dizziness, this should be evaluated urgently (same day, emergency department).
- Even without acute symptoms, ST depression with tachycardia warrants prompt medical review - a cardiology workup including blood tests (troponin, CBC, thyroid function) and possibly a stress test or echocardiogram may be needed.
