Precise pacing artefact detection
Original language description
Cardiac resynchronization therapy (CRT) provides major protection against heart failure events in patients with left bundle branch block (LBBB). While normal left ventricular (LV) contraction is rapid and synchronous, LBBB exhibits significant regional contraction delay: the septal region is activated first and contracts against a non-activated lateral LVnwall. Thus, the lateral wall region is being stretched and, when finally activated, contracts against a high preload. This mechanical dyssynchrony impairs the efficiency of ventricular contraction, reduces stroke volume, and increases workload and LV volumes. Optimising interventricular stimulation delay (VVD) in patients with CRT can be associated with additionally decreased dyssynchrony, improved cardiac output and finally in a reduction of heart failure symptoms. However, while atrioventricular delay change (AVD) has a strong influence on blood filling and can be detected by echocardiographic methods, VVD causes mostly small hemodynamic changes very often under the echocardiographic measurement error threshold. Consequently, the main criterion of VVD positive effect on ventricular dyssynchrony is inaccurate QRS duration (QRSd) shortening detection.
