1. A system comprising:
- a first implantable medical device (IMD) comprising;
an implantable cardiovascular pressure sensor interface unit, the cardiovascular pressure interface unit configured to receive a sensor signal representative of a pulmonary arterial (PA) pressure of a subject;
an implantable cardiac signal sensing circuit configured to receive at least one intrinsic heart signal from at least one implantable electrode;
a memory; and
a trigger detector coupled to the implantable cardiovascular pressure sensor interface unit, the implantable cardiac signal sensing circuit, and the memory, wherein the trigger detector is configured to;
detect a triggering event from a sensed cardiac signal;
detect one or more PA pressure-associated events in response to the detected triggering event;
store PA pressure sensor signal data and one or more annotations of the one or more detected PA pressure-associated events in response to the detected triggering event, the PA pressure data and the one or more detected PA pressure-associated event annotations stored in temporal association with sensed cardiac signal data, wherein the trigger detector is configured to detect an episode of cardiac arrhythmia using the PA pressure data, the one or more PA pressure-associated event annotations, and the sensed cardiac signal data; and
initiate delivery of device based therapy in response to detecting the episode of cardiac arrhythmia.

Abstract
A system comprises an external medical device configured to communicate with a first implantable medical device (IMD). The external medical device includes a communication circuit and a display. The communication circuit is configured to receive information associated with cardiovascular pressure from the IMD. The external medical device is configured to annotate a waveform on the display to indicate one or more events associated with cardiovascular pressure.
