T wave

The T wave is the electrical potential that arises in the ventricles of the heart after the end of the depolarization process. It reflects the onset of ventricular repolarization, which occurs within a few seconds after the end of depolarization, and is an important indicator of cardiac function.

The T wave has a waveform with a peak that reaches its maximum 1-2 seconds after the end of the S wave. It also has a negative part, called the U wave, which appears before the T wave and reflects the process of depolarization in the atria.

T wave analysis helps assess the condition of the heart muscle and identify possible heart rhythm disturbances. For example, a lengthening of the T wave may indicate a slowdown in ventricular repolarization and a decrease in cardiac contractility, and a shortening of the T wave may indicate an acceleration of repolarization and an increase in cardiac contractility.

In addition, T wave analysis can help identify cardiac conduction abnormalities, such as conduction blocks or arrhythmias, which can lead to serious health consequences.

Thus, the T wave is an important diagnostic tool in cardiology and can help the doctor assess the condition of the heart and identify possible problems.

Introduction

The T wave is an electrical signal in the electrocardiogram (ECG) that reflects the end of the process of ventricular repolarization. It is called “T” - from the word “Terminal” or “terminal potential”, which means “final potential”.

Target

The purpose of this article is to study the electrical nature of the T wave and its clinical significance for the diagnosis and monitoring of the cardiovascular system.

Main part

An electrocardiogram (ECG) contains information about the electrical potential of the heart during the cardiac cycle. The P wave is an excitatory potential that appears before the T wave on the ECG. Prong
