Claim 8:
9. An apparatus configured to approximate left ventricular end diastolic pressure (LVEDP) using data from non-invasive ECG and pressure sensors, comprising: at least one processor coupled to a memory, to a non-invasive hemodynamic waveform pressure sensor, and to a non-invasive electrocardiogram (ECG) sensor, wherein the memory holds program instructions that when executed by the at least one processor cause the apparatus to: receive hemodynamic waveform data from the non-invasive hemodynamic waveform pressure sensor and ECG data from the non-invasive ECG sensor; synchronize, the hemodynamic waveform data and the ECG data; and calculate an LVEDP based on time features and waveform features of the hemodynamic waveform data and the ECG data.
