Use of left ventricular flow mapping in echocardiographic optimization of atrioventricular delay
EUROPEAN HEART JOURNAL-CARDIOVASCULAR IMAGING(2015)
摘要
Optimal atrioventricular delay (AVD) in a patient with cardiac resynchronization therapy (CRT) showed discrepant values between the ‘iterative method’ (80 ms), left ventricular outflow tract (LVOT) velocity-time integral (VTI) (120–140 ms), and flow …
