Abstract
An implantable medical device, such as a pacemaker, for electrically stimulating the heart to beat includes two or more node logic units connected by communication paths over which signals between nodes are conducted. Each node can provide pacing energy to an electrode and amplify electrical signals from the electrode. In response to detecting an electrical event from the electrode or pacing an electrode, each node generates a sense signal or a pace signal. The sense and pace signals form each node can be transmitted to all other nodes with or without a time delay. The time delays between nodes are provided by delay modules controlled by a processor. As such, the implantable medical device can be configured to provide a variety of pacemaker therapies.
