| Description | The flexible electro-optical recording system, which allows simultaneous recording of electrograms from orthogonal leads and action potentials from an arbitrary site on heart surface, is presented. The recorded action potentials are disturbed with noise from multiple sources. A robust QRS-complex detector with the following modified averaging with filtered residue is proposed. Adding the filtered residue back to the averaged signal helps to keep information on trends in the signal. |
