The patients with LVR have longer repolarization time, especially the late phase-TpeakTend, which represents transmural dispersion of repolarization. Its prolongation seems to be related to local attributes of myocardium and global function of the left ventricle but unrelated to the autonomic nervous influences. Remodeling with moderate LV systolic dysfunction is associated with insignificant decrease in HRV indices and preserved circadian variability.

Left ventricular (LV) diverticulum represents a rare and frequently asymptomatic congenital anomaly, which is incidentally discovered during routine transthoracic echocardiography. We present a case of a 66-year-old female patient who was admitted to the cardiology department due to incidental finding of a tumor-like mass associated with the posterior mitral leaflet. Preliminary echocardiographic evaluation revealed a solid structure, suspected of mitral annulus calcification or LV malignancy. However, cardiac contrast-enhanced computed tomography confirmed the presence of LV diverticulum, partially filled with calcified thrombus. Conservative management was recommended. This case underscores the importance of multimodality imaging for differentiation of LV tumor-like structures.
