Figure 3From: Implementation of seven echocardiographic parameters of myocardial asynchrony to improve the long-term response rate of cardiac resynchronization therapy (CRT)Echocardiographic improvement after CRT: Individual LVEF at baseline and after CRT in the in the echo-guided CRT group (n = 16, solid lines). The mean LVEF (± SD) in the echo-guided CRT group is shown in black (dashes line) and for the controls in grey (dotted line).Back to article page
