Abstract
An apparatus and method for detecting a pace pulse signal are described. The apparatus and the method include receiving a plurality of sample signals from one ECG lead, measuring a first-level noise of the plurality of sample signals during a first time interval, measuring a second-level noise of the plurality of sample during a second time interval, where the second time interval is different from the first time interval, generating one or more dynamic thresholds based on at least one of the measured first-level noise and the second-level noise, and detecting, based on the one or more dynamic thresholds, at least one of a start point, a peak point and an endpoint of the pace pulse signal from the plurality of sample signals.
Claims12
A method for detecting a pace pulse signal, comprising:
- receiving a plurality of sample signals from one electrocardiogram lead configured to be connected to a patient;
- measuring a first-level noise of the plurality of sample signals during a first time interval by calculating a first difference between a first minimum value and a first maximum value of the plurality of sample signals during the first time interval;
- measuring a second-level noise of the plurality of sample signals during a second time interval, the second time interval being different from the first time interval by calculating a second difference between a second minimum value and a second maximum value of the plurality of sample signals during the second time interval;
- generating at least one dynamic threshold based on the measured first-level noise and the second-level noise;
- and
- based on the at least one dynamic threshold, detecting from the plurality of sample signals at least one of a start point, a peak point and an endpoint of the pace pulse signal.
An apparatus for pace pulse detection comprising:
- one or more processors;
- and
- a computer-readable medium storing instructions that, when executed by the one or more processors, performs operations comprising:
- receiving a plurality of sample signals from each of at least one electrocardiogram, ECG, lead;
- measuring a first-level noise of the plurality of sample signals during a first time interval, by calculating a difference between a first minimum value and a first maximum value of the plurality of sample signals during the first time interval;
- measuring a second-level noise of the plurality of sample signals during a second time interval, the second time interval being different from the first time interval, by calculating a second difference between an second minimum value and a second maximum value of the plurality of sample signals during the second time interval;
- generating at least one dynamic threshold based on the measured first-level noise and the second-level noise;
- and
- based on the at least one dynamic threshold, detecting from the plurality of sample signals at least one selected from the group of a start point, a peak point and an endpoint of the pace pulse signal.
