A system for heart performance characterization and abnormality detection comprises an input processor and at least one signal processor. The input processor receives, sampled data representing a patient blood pressure signal and a concurrently acquired electrocardiogram (ECG) signal representing heart electrical activity of the patient. The at least one signal processor, synchronizes the patient blood pressure signal and the heart electrical activity signal, identifies at least two points of a heart electrical activity signal cycle, integrates signal data values representing the amplitude of the patient blood pressure signal of a segment between the identified two points to derive an integral value over time duration of the segment representing an area under the blood pressure signal waveform between the identified two points and in response to the derived integral value, initiates generation of a message associated with a medical condition of the patient.
