An apparatus for securing a sensor at the heart is formed based on a modified, branched, pacemaker lead to provide a heart anchor lead where two anchors are coupled to a single main lead rather than there being just a single anchor. Thus, the proposed heart anchor lead comprises a single main lead, a sensor included within the main lead, in which the sensor has a distal end and a proximal end, a first anchor coupled to the distal end of the sensor and extending outward from the distal end of the sensor, and a second anchor coupled to the proximal end of the sensor and extending outward from the proximal end of the sensor in a direction that forms an angle with the first anchor. The heart anchor lead can optionally also have a pacemaking function.
