Zusammenfassung:A catheter having an ablation electrode with at least one microelectrode configured to sense monophasic action potential signals and a force sensor configured to sense contact force of the microelectrode against tissue surface, may be used to acquire pre-ablation MAP signals with monophasic characteristics and post-ablation MAP signals to determine presence or absence of monophasic characteristics in the latter in assessing quality or success of ablation procedure and lesion formation.
