LEADLESS PACEMAKER AND METHODS FOR ELECTRICALLY STIMULATING CARDIAC TISSUE, SENSING ELECTRICAL SIGNALS AND COMMUNICATING BETWEEN A LEADLESS PACEMAKER AND AN EXTERNAL DEVICE

摘要

The disclosure relates to a leadless pacemaker (1) comprising at least one fixation element (2) for fixating the leadless pacemaker to cardiac tissue, a communication unit (3) which is electrically connected to said fixation element (2), so that said fixation element (2) is configured to act as a communication antenna for transmitting signals generated by said communication unit (3) to an external device and/or receiving signals from an external device, and a therapy unit (4) for generating electrical signals to electrically stimulate cardiac tissue, wherein said fixation element (2) is configured to act as an electrode for electrically stimulating cardiac tissue and/or sensing electrical signals of the cardiac tissue. Furthermore, the disclosure relates to a method for electrically stimulating cardiac tissue, a method for sensing electrical signals of cardiac tissue by means of the leadless pacemaker (1), and a method for communicating between a leadless pacemaker (1) and an external device.
