摘要： A method and apparatus for detecting heartbeats obtains ECG data from a plurality of ECG waveforms, which are in turn obtained from signals received from a plurality of ECG electrodes. QRS detection logic detects heartbeats in the ECG data. This logic calculates an activity function from a subset of the plurality of ECG waveforms determined to be least noisy, and uses this activity function to search for heartbeats. The QRS detection logic allows for true heartbeats to be detected while discarding false "noise" beats.

摘要： A method and apparatus for obtaining heartbeat measurements obtains ECG data from a plurality of ECG waveforms, which are in turn obtained from signals received from a plurality of ECG electrodes. QRS detection logic detects heartbeats in the ECG data. Classification logic classifies heartbeats into categories based on shape and/or timing. Alignment logic aligns the heartbeats. Representative heartbeat creation logic creates a representative heartbeat from the aligned heartbeats. Measurement logic measures various aspects of the representative heartbeat. This logic analyzes the ECG waveforms to determine an earliest QRS onset and latest QRS offset, and uses these values to perform a variety of measurements. This results in robust measurements even in very noisy environments. The representative heartbeat is displayed, either alone or with heart rate and/or other measurement information, to the cardiologist or medical professional for diagnosis of the condition of the patient's heart, such as a diagnosis of coronary artery disease, based on finding a depressed ST segment in the representative heartbeat of a patient undergoing a stress or exercise test.

摘要： A method and apparatus for calculating a heart rate obtains ECG data from a plurality of ECG waveforms, which are in turn obtained from signals received from a plurality of ECG electrodes. Heart rate calculation logic calculates the patient's heart rate. This logic determines the intervals between the heartbeats detected in the ECG data, discards a percentage of the shortest and longest intervals, and averages the remaining intervals to arrive at the patient's heart rate. This results in a robust calculation of the heart rate even in the presence of noise falsely detected as heartbeats and missed beats, both of which are common in noisy environments. The heart rate is displayed to the cardiologist or medical professional for diagnosis of the condition of the patient's heart.

摘要： A method and apparatus for classifying heartbeats obtains ECG data from a plurality of ECG waveforms, which are in turn obtained from signals received from a plurality of ECG electrodes. QRS detection logic detects heartbeats in the ECG data. Classification logic classifies the detected heartbeats into categories based on shape and/or timing. This classification is done by comparing each heartbeat against a group of templates corresponding to one or more heartbeat classifications. The templates are updated to track changes in the morphology of the heartbeats. The heartbeat classification is displayed to the cardiologist or medical professional for diagnosis of the condition of the patient's heart.

摘要： A method and apparatus for creating a representative heartbeat obtains ECG data from a plurality of ECG waveforms, which are in turn obtained from signals received from a plurality of ECG electrodes. QRS detection logic detects heartbeats in the ECG data. Classification logic classifies heartbeats into categories based on shape and/or timing. Alignment logic aligns the heartbeats. This logic slides the heartbeats occurring at various times across a stationary alignment template to calculate when the heartbeats are best aligned, and performs adjustments to reduce the effects of noise or jitter on the different ECG waveforms. Representative heartbeat creation logic creates a representative heartbeat from the aligned heartbeats. This logic time slices through the aligned heartbeats, discarding a percentage of the smallest and largest magnitudes of the aligned heartbeats at each instance of time, and averaging the remaining magnitudes to produce a representative heartbeat. This trimmed averaging technique results in a high quality representative beat, since samples from noise and misclassified beats are discarded. The representative heartbeat is displayed, either alone or with head rate and/or other measurement information, to the cardiologist or medical professional for diagnosis of the condition of the patient's head, such as a diagnosis of coronary artery disease, based on finding a depressed ST segment in the representative heartbeat of a patient undergoing a stress or exercise test.

摘要： A computer-based detection method employable with a sleeping subject for aiding in the differential-character diagnosis and treatments of apneic events includes gathering heart-sound data, including S1 data and S2 data. A combined time-frequency-intensity (TFI) analysis, of the gathered data is performed, in a continuous manner, over a selected time period. Based on the performing and the performed TFI analysis, an output is produced which is indicative of the presence and character of any detected apneic event.
