Abstract:
1. A method for operating an electrocardiography (ECG) machine having a CPU, a memory, a display, and a software program in said memory for operating said ECG machine to identify and display low hysteresis optimum electrocardiography (ECG) heart rates by said electrocardiograph machine comprising the steps of: providing said electrocardiograph (ECG) machine to receive and record electrocardiograph signals from a patient who is continuously monitored by said ECG machine for one or more transient conditions of the electrical activity of the heart for an extended period of time; operating the ECG machine to record ECG signals generated by the patient's heart, said ECG signals occurring over an extended period of time and including at least one window of time, said window of time including a expected extraction time for an instantaneous and stable heart rate processing the ECG signals to calculate the heart rate for heart beats that occur during the window and to determine the average heart rate for an observation period preceding each heart beat during the window; and displaying a stable heart rate occurring during said window wherein said displayed stable heart rate is one of the heart rates in the windows that is closest in magnitude to its corresponding average heart rate; and wherein said displayed stable heart rate indicates a low hysteresis optimum electrocardiography (ECG) heart rate.
