Could u explain to me what exactly non specific t wave abnormality means i don't understand what t wave is?

Not diagnostic : You have to think of an EKG as a map. It's a pattern of vectors. It visually documents the direction, timing, and strength of electrical activity in your heart. The T-wave represents the restoration of electrical baseline charge aka "repolarization" of both ventricular muscles, like recharging a battery. Wave changes need to be interpreted in context by a qualified clinician, not the machine.

T wave: Is the final hump you see in an EKG complex. It represents the "repolarization" of the atria (top chambers) of the heart. It serves to mark the point where atria are "recharging" to allow for the next cycle of heart pumping. Non specific changes refer to electrical abnormalities in the appearance of the "hump" that has no clear concerning pathologic cause.

T waves: See the added diagram. The large wave on the EKG is called the QRS complex. It appears when the ventricles contract and the T wave after it is a repolarization wave that occurs when the ventricles relax. Non specific T wave abnormalities may mean that the T waves are flattened or inverted. This is not specific for any abnormality. There are many causes for this.

Ecg: There are several reasons why t waves change, not always pathological , if no pathological reasons are found then we call it nonspecific t wave changes

Description: The ECG tracing is an electrical tracing of your heart. Non specific t wave abnormality may be written by a doctor or by the ECG machine using its algorithm code to interpret the ECG. It means that there is no clear diagnostic pattern in the ECG and is not useful for making a diagnosis. Nothing to worriy about
