Why the study?
Can a statistical approach using specific electrogram variables accurately determine local myocardial electrical activation during mapping?
Can a statistical approach using specific electrogram variables accurately determine local myocardial electrical activation during mapping?
A statistical approach using specific derivatives of extracellular potentials can objectively discriminate local myocardial electrical activation from distant activity during mapping.
