Abstract:
1. A method comprising: introducing current between a first pair of electrodes configured for placement internally in a patient, the first pair of electrodes being from a unitary subcutaneous cardiac defibrillation device, wherein the unitary subcutaneous cardiac defibrillation device is leadless and comprises a housing containing a power supply, capacitor, and operational cardiac defibrillation circuitry; triggering a potential measurement between a second pair of electrodes configured for placement internally in a patient, wherein the second pair of electrodes is from an implantable cardiac device, wherein wireless communication between the unitary subcutaneous cardiac defibrillation device and the implantable cardiac device allows for proper triggering, wherein the implantable cardiac device comprises a subcutaneous housing and a lead connected to the housing, wherein the lead is implanted within the heart, wherein at least one of the second pair of electrodes is disposed on the lead, and wherein the unitary subcutaneous cardiac defibrillation device is discrete from the implantable cardiac device; measuring potential between the second pair of electrodes; and based at least in part on the measuring and the introducing, determining a cardiac condition wherein the unitary subcutaneous cardiac defibrillation device performs the introducing and the implantable cardiac device performs the measuring.
