Systems and methods evaluate electrical contact between the myocardium and one or more electrodes inside the heart. The systems and methods electrically sense electrical contact between the myocardium and electrodes and generate unitary contact-indicating outputs indicating the presence or absence of electrical contact between the myocardium and each particular electrode. The systems and methods also correlate the electrode-specific unitary outputs to generate a compound contact-indicating output. The compound output represents the aggregate of the electrical contact between the myocardium and multiple electrodes on a multiple electrode array.

A system for evaluating electrical contact between the myocardium and a multiple electrode array inside the heart, the multiple electrode array comprising first and second circumferentially spaced splines for contacting circumferentially spaced endocardial regions, each spline supporting at least one electrode, the system comprising first means for electrically sensing electrical contact between at least one electrode on the first spline and the myocardium and for generating a first unitary contact-indicating output indicating the presence or absence of the electrical contact, and second means, operable independently of the first means, for electrically sensing electrical contact between at least one electrode on the second spline and the myocardium and for generating a second unitary contact-indicating output indicating the presence or absence of the electrical contact, at least one of the first and second means being operable to sense electrical contact by emitting from the respective electrode an electrical signal that activates the myocardium.
