Is nonspecific ST abnormality bad?

Conclusions Persistent, minor, nonspecific ST-T abnormalities are associated with increased long-term risk of mortality due to MI, CHD, CVD, and all causes; the higher the frequency of occurrence of minor ST-T abnormalities, the greater the risk.

What causes a nonspecific ST abnormality?

It has been suggested that nonspecific ST-T changes might represent subclinical coronary artery disease, early left ventricular hypertrophy, increased left ventricular mass, or autonomic imbalance.

How do you interpret ECG results?

When interpreting the heart rhythm, you should look for P waves, which is a sign of atrial excitation. When every P wave is followed by a QRS complex, the ECG shows sinus rhythm. If the P waves are irregular, sinus arrhythmia is likely present.

What does nonspecific ST abnormality on ECG mean?

Background: Nonspecific ST and T wave abnormalities (NSSTTA) on resting ECGs are associated with increased cardiovascular risk, and portend similar hazard ratios to traditional risk factors, such as dyslipidemia, hypertension, and diabetes mellitus (DM).

Is ST depression serious?

ST depression in ECG at entry indicates severe coronary lesions and large benefits of an early invasive treatment strategy in unstable coronary artery disease; the FRISC II ECG substudy.

What is nonspecific ST abnormality in ECG?

Maybe the T wave is flat, oddly-shaped or inverted. Maybe the ST segment is coved, very minimally-depressed or shows some J point elevation. These are referred to as “non-specific” T wave and ST segment changes on the ECG because they are simply not specifically signaling any medical condition.

What causes St abnormality?

The ST Segment represents the interval between ventricular depolarization and repolarization. The most important cause of ST segment abnormality (elevation or depression) is myocardial ischaemia or infarction.
