What does flattening of T wave mean?

What does flattening of T wave mean?

Flattened T waves Flattened T waves are a non-specific finding, but may represent. Ischaemia (if dynamic or in contiguous leads) or. Electrolyte abnormality, e.g. hypokalaemia (if generalised)

Can anxiety cause T wave flattening?

Anxiety-related ECG changes The ECG changes in anxiety are: ST flattening, the commonest finding. Frank ST depression; not rare, especially in hyperventilation. T wave inversion.

What does abnormal T wave on ECG mean?

Problem/Condition. The electrocardiographic T wave represents ventricular repolarization. Abnormalities of the T wave are associated with a broad differential diagnosis and can be associated with life-threatening disease or provide clues to an otherwise obscure illness.

Are flattened T waves normal?

Flattened T waves are often seen in patients with myocardial ischaemia, but they are very non-specific.

Does being nervous affect EKG?

Premature ventricular contractions is one of the manifestations of sympathetic over activity due to anxiety. However, anxiety might induce electrocardiographic (ECG) changes in normal person with normal heart, as in this documented case.

Is Flat T wave normal?

T wave is considered flat when the wave varies from -1.0 mm to + 1.0 mm in height. Hypokalemia or digitalis therapy can cause flattened T wave with a prominent U wave. As hypokalemia progressively worsens, T wave becomes more flatten while U wave becomes more prominent, with progressively deeper ST segment depression.

What do flat T waves mean on an EKG?

Flat T waves can indicate a coronary ischemia (part of your heart muscle is not getting perfused and dies as in an infarct) or hypokalemia. Since you had a normal EKG then a “flat” T wave one, I’d say eat more foods with potassium and check again.

What causes a flat T wave?

Two main causes of both biphasic and flattened T waves include myocardial ischemia and hypokalemia, or a low blood potassium level. “Camel hump” T waves may also indicate hypokalemia, and they are sometimes seen in patients with heart block.

What causes elevated T waves?

A common cause of abnormally large T-waves is hyperkalemia, which results in high, pointed and asymmetric T-waves. These must be differentiated from hyperacute T-waves seen in the very early phase of myocardial ischemia. Hyperacute T-waves are broad based, high and symmetric.

What are normal T waves?

Normal T wave. Normally, T waves are upright in all leads, except aVR, aVL, III and V1 leads. Highest amplitude of T wave is found at V2 and V3 leads. The shape of the T wave is usually asymmetrical with a rounded peak.
