Comparison of ECG and speckle tracking echocardiography of a normal subject and another with advanced interatrial block. ECG (a) and left atrial (LA) strain rate (SR) echocardiography (c) in normal subjects, with normal SR of LA contraction (blue arrow) and reservoir (red arrow) phases. ECG with advanced interatrial block (b); red arrows show biphasic or +/− P wave morphology and with decreased SR of LA contraction (white arrow) and reservoir (yellow arrow) phases (d)
