Method for localizing a site of origin of an electrical heart activity

A method for localizing an origination site of electrical heart activity comprising the steps of:

• providing a heart model and providing a thorax model and embedding said heart model in said thorax model, and storing said comparison values in a data bank;
• using said heart model embedded in said thorax model, generating a plurality of comparison values representing modeled heart activities respectively originating at a plurality of known positions;
• measuring body surface potentials produced by heart activity of a subject at a plurality of measuring points using a multi-channel measuring system and obtaining measured values respectively representing the body surface potentials at said measuring points, generating a characteristic value from said measured values and storing said characteristic value;
• comparing said characteristic value to each of said comparison values in said data bank and identifying a comparison value having a highest similarity to said characteristic value;
• and
• identifying the known position of said comparison value having the highest similarity to said characteristic value and emitting said position as the site of origin of the heart activity which produced said body surface potentials.
