A method for modulating one or more functions of an implanted medical device is disclosed. The method includes measuring a cardiovascular pressure of a patient; evaluating the cardiovascular pressure based on one or more characteristics of a cardiac cycle of the patient at the time the pressure was measured; and modulating one or more functions of the device based on the pressure. Also disclosed is a method for assessing a cardiovascular pressure of a patient with an implanted medical device that includes detecting one or more characteristics of a cardiac cycle of the patient's heart; detecting the cardiovascular pressure of the patient; classifying the cardiovascular pressure based on one or more characteristics of the cardiac cycle of the patient's heart; and displaying the cardiovascular pressure along with the classification. Also disclosed is a system for collection and display of a cardiovascular pressure of a patient.

1. A system for collection and display of a cardiovascular pressure of a patient, wherein the patient has an implanted medical device capable of providing a stimulus to the patient's heart, the system comprising: (a) one or more cardiac cycle sensors capable of generating a first signal indicative of a characteristic of a cardiac cycle of the patient's heart;(b) one or more pressure sensors capable of generating a second signal indicative of a cardiovascular pressure of the patient;(c) one or more transmitters configured to transmit the first and second signal to a database capable of storing patient information in the form of cardiac cycle data and pressure data;(d) a processor configured to classify the cardiovascular pressure based on the cardiac cycle data, wherein the cardiac cycle data includes whether the cardiovascular pressure is determined during a cycle in which a stimulus was delivered to the patient's heart by the implantable medical device, whether the cardiac cycle is intrinsic at the time that the cardiovascular pressure is determined, what type of stimulus was applied that could affect the determined cardiovascular pressure or a combination thereof; and(e) a display showing the classification of the cardiovascular pressure. 2. The system of claim 1, wherein the cardiac cycle sensor is configured to be implanted within the patient. 3. The system of claim 1, wherein the cardiac cycle sensor is configured to be located external to the patient. 4. The system of claim 1, wherein cardiovascular pressure comprises pulmonary artery pressure. 5. The system of claim 1, wherein one or more cardiovascular pressure sensors are configured to be implanted within the patient. 6. The system of claim 1, wherein one or more cardiovascular pressure sensors are configured to be located external to the patient. 7. The system of claim 4, wherein cardiovascular pressure comprises intravascular pressure. 8. The system of claim 1, wherein cardiovascular pressure comprises an intracardiac pressure. 9. The system of claim 1, wherein the system further comprises a hemodynamic sensor. 10. The system of claim 1, wherein pressure comprises at least one of a diastolic pressure, a systolic pressure, a mean pressure, a pulse pressure, an end expiratory diastolic pressure, an end expiratory systolic pressure, a rate of change of a pressure, and a mean pressure. 11. The system of claim 1, wherein the characteristic of a cardiac cycle comprises at least one of systole, diastole, and an intervening phase. 12. The system of claim 1, wherein the pressure sensor is at least one of a direct pressure sensor and an indirect pressure sensor. 13. The system of claim 1, wherein the display comprises at least one of a time trend, a bar chart and a histogram. 14. The system of claim 1, wherein the system further comprises at least one of a subcutaneous electrogram sensor, an acceleration sensor, a temperature sensor, a chemical sensor, an acoustic sensor, and an impedance sensor. 15. The system of claim 1, wherein the system further comprises a physiological sensor wherein the sensor is configured to measure at least one of a heart rate, a respiratory rate, a cardiac cycle, a movement, a temperature, an impedance, a posture, a heart sound, a respiratory sound, a blood analyte. 16. The system of claim 1, wherein the implantable medical device is selected from pacemakers, implantable cardioverter defibrillators (ICDs), and cardiac resynchronization therapy (CRT) devices.
