In the filtered signal the peak corresponding to the one evaluated on the integrated signal is searched and compared with a threshold, calculated in a similar way to the previous step: T h r e s h o l d F = N o i s e L e v e l F + 0.25 ( S i g n a l L e v e l F − N o i s e L e v e l F ) {\displaystyle Threshold_{F}=NoiseLevel_{F}+0.25 ...

Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [ 5 ] using electrodes placed on the skin.

If at least three different shaped P waves can be seen in a given ECG lead tracing, this implies that even if one of them arises from the SA node, at least two others are arising elsewhere. This is taken as evidence of multiple (i.e. at least two) ectopic foci , and is called multifocal (or more correctly, multiform) atrial rhythm if the rate ...
