An ECG (electrocardiogram) report provides information about the electrical activity of the heart. The description "flattened T Wave (V5, V6), low T wave V4" refers to specific findings in the T waves of the ECG waveform recorded from leads V5, V6, and V4.
The T wave is a component of the ECG that represents the repolarization (recovery) phase of the ventricles of the heart. Normally, the T wave appears as a rounded or slightly asymmetrical waveform.
The presence of a "flattened T wave" in leads V5 and V6 indicates an abnormality in the repolarization phase of the ventricles in those specific regions of the heart. Instead of the expected rounded or asymmetrical shape, the T waves in those leads appear flattened or less pronounced.
Additionally, the description "low T wave V4" suggests that the T wave in lead V4 is smaller in amplitude compared to what is typically observed.
These findings may indicate various underlying conditions or abnormalities, including:
Myocardial ischemia: Reduced blood flow to the heart muscle due to narrowed coronary arteries.
Myocardial infarction (heart attack): Blockage of a coronary artery resulting in damage to the heart muscle.
Ventricular hypertrophy: Thickening of the ventricular walls due to increased workload on the heart.
Electrolyte imbalances: Abnormal levels of electrolytes (such as potassium or magnesium) in the blood, which can affect cardiac electrical activity.
Medication effects: Some medications can cause changes in the T wave morphology.
It's important to note that an ECG report provides an initial observation, but a complete diagnosis should be made by a qualified healthcare professional who takes into account the patient's clinical history, symptoms, and further diagnostic tests if necessary.
