What does it mean nonspecific changes in ventricular repolarization?

The anomalies of ventricular repolarization are generated by alterations of some proteins responsible for the transport of potassium and sodium ions across the membrane of heart cells, a fundamental function for maintaining the normal electrical activity of the heart.

What are the ECG waves?

The entire path should be read from left to right. The ECG consists of positive ("P, R, T") and negative ("Q, S") waves. Positivity or negativity refers to the "isoelectric line" which represents zero and is the baseline of the electrocardiogram.

What does it mean non-specific?

- Not specific; in medical language, inflammation a., any inflammation sustained by banal germs and which is therefore neither tuberculous nor luetic in nature, nor attributable to microorganisms responsible for particular and well-defined diseases.

What does the Q wave represent?

The "Q wave" is negative, small in size, and corresponds to the depolarization of the interventricular septum, the vector produced goes from left to right; the "R wave" is a very high positive peak, corresponding to the depolarization of the apical part of the ventricles; it is so evident since it is related to ...

What does it mean nonspecific symptoms?

-there). - Not specific; in medical language, inflammation a., any inflammation sustained by banal germs and which is therefore neither tuberculous nor luetic in nature, nor ascribable to microorganisms responsible for particular and well-defined diseases.

How is a heart attack diagnosed?

The diagnosis of myocardial infarction is based on the search in the patient's blood for specific markers of cardiac damage, together with the execution of an electrocardiogram to search for significant changes in the electrical activity of the heart (remember, in this regard, that the damaged muscle tissue is ...

Why is the Q wave negative?

The Q wave is the first negative wave; it is due to the depolarization of the middle third of the SIV from left to right; it has a duration of less than 0.04 sec, has an amplitude less than 1/4 of that of the R wave that follows it; it is present in the branches: DI, aVL, V5, V6.
