Septic shock is a critical condition associated with high mortality. Transthoracic echocardiography is widely used to evaluate cardiac function and guide treatment. Left and right atrial strain (LAS and RAS) measured via speckle tracking echocardiography have shown prognostic value in cardiovascular diseases. However, differences exist between echocardiographic software, leading to challenges in result comparability. This study aims to compare LAS and RAS measurements between ECHOPAC and UWS software, evaluate AutoStrain technology, and assess reproducibility across observers. The study is non-interventional and will use retrospective echocardiographic data from patients treated for septic shock. The findings will contribute to improving measurement standardization in critically ill patients.
