    摘要: A drug delivery system detects a cardiac condition indicative of a need for increasing a cardiac metabolic level and, in response, releases a drug into tissue or blood to shift a source of metabolically synthesized energy fueling cardiac contraction from fatty acid to glucose. One example of such a system includes an implantable device detecting an ischemia and a transdermal drug delivery device delivering a drug when an ischemic condition is detected. Another example of such a system includes one or more implantable devices detecting a predefined change in cardiac metabolic level and delivering a drug when the change is detected. Such systems are applied to treat, for example, patients suffering ischemia and/or heart failure and patients having suffered myocardial infarction.

    摘要: An implantable pacing device for delivering ventricular pacing may be configured to intermittently reduce the AVD interval for beneficial effect in patients with compromised ventricular function (e.g., HF patients and post-MI patients). The AVD interval may be reduced in an AVD reduction mode, by shortening the AVD in an atrial triggered ventricular pacing mode or by switching to a non-atrial triggered ventricular pacing mode (e.g., VVI) and delivering paces at a rate above the intrinsic rate. The physiological effects of AVD reduction may be either positive or negative on cardiac output, depending upon the individual patient.
