Figure 2From: Influence of the atrio-ventricular delay optimization on the intra left ventricular delay in cardiac resynchronization therapyAssessment of the left-atrial electromechanical action = LA-EAClong. LA = left atrial deflection (see oesophagus- ECG). EAClong = the end of the A-wave in an unphysiologically long AV-intervall. In this particular patient the LA-EAClang is 160 msBack to article page
