ST Depression
ST depression is a finding on an electrocardiogram (ECG) that may suggest a heart problem, especially when the heart isn’t getting enough oxygen. It often shows up as a dip in the ST segment of the ECG line. While it can have different causes, the most common reason is reduced blood flow to the heart muscle, also known as myocardial ischemia.
What ST Depression Means
The ST segment on an ECG reflects the time between the heart’s contraction and relaxation. When this segment dips below the baseline, it’s called ST depression. This may mean part of the heart muscle isn’t getting enough oxygen. This can happen during stress, exercise, or in cases of narrowed arteries.
Types of ST Depression
There are three main types:

Symptoms and Causes
ST depression can occur with or without symptoms. When symptoms happen, they may include:
- Chest pain
- Shortness of breath
- Fatigue
- Dizziness
Common causes include:
- Coronary artery disease
- Myocardial ischemia
- Heart attack
- Electrolyte imbalances
- Medication side effects
Diagnosis
Doctors often find ST depression during a stress test or ECG. To understand the cause, other tests may include:
- Cardiac enzymes
- Echocardiogram
- Coronary angiography
The goal is to find if the heart is getting enough blood and to check for blockages.
Treatment
Treatment depends on the cause:
- If it’s due to ischemia, doctors may recommend medications, lifestyle changes, or procedures like stents.
- For heart attacks, emergency care is needed.
- If caused by other issues like medications or imbalances, fixing those may resolve the problem.
Lifestyle changes help prevent further problems:
- Quit smoking
- Exercise regularly
- Eat a heart-healthy diet
- Manage stress
- Control blood pressure and cholesterol
Prognosis
The outlook depends on the cause and how early treatment begins. ST depression caused by reversible ischemia often improves with care. Ignoring it, however, increases the risk of heart attacks or long-term heart damage.
BaleDoneen Method Approach
At BaleDoneen, we take ST depression seriously. Our method looks deeper than symptoms. We use advanced imaging and lab testing to understand what’s really going on inside the arteries. Whether it’s a warning sign of heart disease or a result of another problem, we find the cause and create a personal plan to treat it.
We focus on prevention. We help patients reduce risk by managing inflammation, improving artery health, and making sure the heart gets enough blood.
