Time Voltage Index

Stress index over time

The time-stress index (TI) is an indicator that allows you to assess the change in mechanical stress of the myocardium over time. This index is used to measure the contractility of the heart and determine its functional state.

The method for measuring INT is based on measuring intragastric pressure (IGP) using a catheter that is inserted into the cavity of the left ventricle. Then the area enclosed under the curve, which reflects the dynamics of the airborne railway, is measured. This area is called the “area under the curve.”

INT is calculated as the ratio of the area under the curve to the area that can be obtained if the heart is working in an optimal state. If the INT is higher than normal, it may indicate the presence of heart problems such as coronary heart disease, arrhythmias and other diseases.

In addition, INT can be used to evaluate the effectiveness of treatment for cardiovascular diseases. For example, when carrying out drug therapy or surgical operations on the heart, INT allows you to assess how effectively the treatment was carried out and what changes occurred in the functioning of the heart.

Overall, the time stress index is an important tool for diagnosing and monitoring cardiac health, as well as for assessing the effectiveness of various treatments for cardiovascular diseases.
