Claim 14:
15. A method for approximation of left ventricular end diastolic pressure (LVEDP) using data from non-invasive ECG and pressure sensors coupled to a computing apparatus, the method comprising:
receiving, by at least one processor of the computing apparatus, hemodynamic waveform data from a non-invasive pressure sensor coupled to a patient and electrocardiogram (ECG) data from a non-invasive ECG sensor coupled to the patient;
determining, by the at least one processor, a time difference indicative of a delay between the hemodynamic waveform data and the ECG data; and
calculating, by the at least one processor, an LVEDP based on time features and waveform features of the hemodynamic waveform data and the ECG data and the time difference, the time difference being used to determine synchronized portions in time of the hemodynamic waveform data and the ECG data.
