A method and apparatus for predicting acute response to cardiac resynchronization therapy is disclosed. The method can comprise measuring a first interval during an intrinsic systolic cycle and measuring a second interval during a stimulated systolic cycle. The acute response can be predicted by comparing...http://www.google.ca/patents/US20020161307?utm_source=gb-gplus-sharePatent US20020161307 - Method and apparatus for predicting acute response to cardiac resynchronization therapy
