A method for analyzing arrhythmia in real time and an electrocardiogram monitoring device is disclosed. The method for analyzing arrhythmia in real time includes: acquiring a QRS template set currently used for arrhythmia analysis; determining whether each QRS template in the QRS template set is reliable; displaying information of a QRS template when the QRS template set contains an unreliable QRS template; determining the QRS template set according to an operation performed by a user on the information of the QRS template; and acquiring real-time electrocardiogram data, performing arrhythmia analysis on the real-time electrocardiogram data by using a determined QRS template set, and outputting an arrhythmia analysis result of the real-time electrocardiogram data in real time. The method for analyzing arrhythmia in real time may achieve the correction of a template of a special waveform by means of editing a currently created QRS template. When the same type of waveform is analyzed again, a correct arrhythmia analysis result may be provided, which may improve the accuracy of arrhythmia analysis and improve the quality of electrocardiogram monitoring.

A method and an apparatus for determining at least one smoothed data point (t.sub.k, s.sub.k) within a stream of data points {t.sub.i, s.sub.i} with 1≤i≤z, k<z is disclosed. Herein, the stream of data points {t.sub.i, s.sub.i} is consecutively acquired in a manner that a data point (t.sub.i, s.sub.i) is acquired after an acquisition of a preceding data point (t.sub.i−1, s.sub.i−1), wherein each data point (t.sub.i, s.sub.i) comprises a valid value or an invalid value or a missing value for the signal s.sub.i at a time t.sub.i. Herein, the signal s.sub.i at the time t.sub.i comprises physical, chemical, biological, environmental, and/or technical data acquired by means of a technical set-up. According to the method, a set of data points is provided, wherein for each smoothed data point (t.sub.k, s.sub.k) a smoothing set is created. For each smoothed data point (t.sub.k, s.sub.k), trailing data resulting from large gaps are removed until it is verified whether the smoothing set comprises a minimal number of data points. Thereafter, for each smoothed data point (t.sub.k, s.sub.k) an initial slope set is calculated, on which at least one exponential smoothing is applied, in which cause an at least once modified slope set is determined. By integrating the at least once modified slope set, a value for the smoothed data point (t.sub.k, s.sub.k) is determined and returned. The method provides a good degree of smoothing without introducing any lag time and with minimal distortions, and is capable of reporting derivatives for the set of smoothed data points at the same time. The method is particularly suited in real-time or nearly real-time measurements which may comprise large gaps within the stream of data points.
