ABSTRACT:
An apparatus and method for sensing cardiac function in a patient, particularly adaptable to being worn by an ambulatory patient. Including sensor to receive ECG signals in at least plane of the patient chest area, and an analyzer to derive a signal representation of the electrical axis of the patient heart. Changes in the signal representation can be evaluated to include heart condition. The axis analyzer and other ECG information can be used to generate rate information used in conjunction with the heart axis signal representation. Incidence of phase zero-crossing of the heart axis signal representation and the magnitude peaks can be used to indicate and distinguish various heart conditions.
