What does flattening of T wave mean?

What does flattening of T wave mean?

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)

What does T wave inversion in inferior leads mean?

T-wave inversion in the anterior and lateral lead groups is independently associated with the risk of CHD, and lateral T-wave inversion is also associated with increased risk of mortality. Inverted T wave in the inferior lead group proved to be a benign phenomenon.

What causes T wave abnormality on EKG?

Primary T-wave abnormalities (ischemia or injury) are due to alterations in myocardial cellular electrophysiology and secondary T-wave abnormalities (bundle branch block or ventricular Hypertrophy) are subsequent to alterations of sequence of ventricular activation.

What ECG changes indicate myocardial ischemia?

Myocardial ischemic-like ECG changes include ST-segment deviations, T wave inversion, and Q-waves. The earliest manifestations of myocardial ischemia typically involve T waves and the ST segment. It is believed that ECG changes in CCS most often represent preexisting ischemic cardiac disease[32].

Is T wave inversion serious?

T-wave inversions in right precordial leads are relatively rare in the general population, and are not associated with adverse outcome. Increased mortality risk associated with inverted T waves in other leads may reflect the presence of an underlying structural heart disease.

Does anxiety cause abnormal T waves?

Abnormal ECG Findings Caused by Anxiety Whether it is due to short-term test nervousness or a chronic condition, anxiety may be associated with certain ECG abnormalities, including T-wave inversion.

What are inferior leads?

Lead II, aVF and III are called inferior limb leads, because they primarily observe the inferior wall of the left ventricle (Figure 18, coordinate system in upper panel). Lead aVL, I and –aVR are called lateral limb leads, because they primarily observe the lateral wall of the left ventricle.

What is inferior ischemia?

Inferior wall myocardial infarction (MI) occurs from a coronary artery occlusion with resultant decreased perfusion to that region of the myocardium. Unless there is timely treatment, this results in myocardial ischemia followed by infarction.
