Abstract

The aim of our study was to evaluate the agreement between tissue Doppler imaging (TDI) methods and electrophysiology study (EPS) concerning the measurement of total atrial conduction time (TACT) and left atrial conduction delay (LACD). Sixty-nine candidates for EPS were included. TACT and LACD were measured in the EPS. The TDI time intervals for each patient were measured using both pulsed-wave (PW) and 2-D color-coded (CC) methods, once from the beginning of the P wave to the beginning of the a′ wave (Tb) and once again to the peak of the a′ wave (Tp) at the mitral annulus. TACT and LACD measured by TDI were not in good agreement with those measured by EPS. There was moderate agreement between PW-Tb and CC-Tb and good agreement between PW-Tp and CC-Tp for the measurement of TACT; nevertheless, agreement was not good in the case of LACD. © 2019 World Federation for Ultrasound in Medicine & Biology
