Abstract
Apparatus for applying a non-excitatory signal to a heart, comprising: at least one electrode, a power source, a wide-field ECG sensor that receives a wide-field ECG signal containing contributions from non-local sized portions of the heart, a controller for selectively electrifying said at least one electrode with a non-excitatory signal from said power source, and a safety filter that inhibits said electrifying responsive to said wide-field ECG signal.

Apparatus for applying a non-excitatory signal to a heart, comprising:
- at least one electrode;
- a power source;
- a wide-field ECG sensor that receives a wide-field ECG signal containing contributions from non-local sized portions of the heart;
- a controller for selectively electrifying said at least one electrode with a non-excitatory signal from said power source;
- and
- a safety filter that inhibits said electrifying responsive to said wide-field ECG signal.
A method of determining if to inhibit the application of a non-excitatory signal to the heart, comprising:
- detecting a non-local ECG trace;
- determining if said trace indicates a normal activation of the heart;
- and
- inhibiting the application of a non-excitatory signal responsive to a negative determination of said trace.
