Complex Qrst

The Qrst complex is a set of waves on an electrocardiogram that reflects the process of depolarization of the ventricles of the heart. It consists of three teeth: Q, R, S and T.

The Q wave is negative and is located in front of the R wave. It reflects the process of ventricular repolarization when potassium ions return to the cell after excitation. The Q wave can be enlarged in various heart diseases such as myocardial infarction, myocarditis or cardiomyopathy.

The R and S waves are positive and are located after the Q wave. They reflect the process of depolarization of the ventricular muscle. The R wave is the largest and characterizes the process of excitation of the ventricles, and the S wave is a small negative wave that follows the R wave and characterizes the process of repolarization.

The T wave is a small positive wave located after the QRS complex. It reflects the process of restoring the resting potential in the ventricles.

The Qrst complex is an important indicator of heart function and can be used to diagnose various diseases. However, to interpret an electrocardiogram, it is necessary to have experience and knowledge in the medical field. Therefore, if you have any questions or concerns about your health, it is recommended that you consult your doctor.

The Qrs complex is a term used in medicine to describe a collection of waves on an electrocardiogram (ECG) that reflect the process of depolarization of the wall of the ventricle of the heart. This term is best characterized by its shape and location on the ECG graph. The value of the Qr complex can reach 0.12 seconds. In addition, the size of the S wave is about 0.06 seconds, the R wave usually reaches 0.0
