1. A multi-sensor patch and signal analyzer that enable safe cardiac ablation, comprising:
a patch configured to be placed on a patient's body, wherein said patch comprises
a plurality of sensors that comprise
one or more electrocardiogram electrodes;
one or more photoplethysmogram sensors; and
one or more accelerometers; and
one or more pulsed field ablation return electrodes configured to be coupled electrically to a pulse generator that is configured to create electrical pulses to induce cardiac ablation within the patient's body; and
a signal analyzer coupled to said plurality of sensors and to said pulse generator, wherein said
signal analyzer is configured to repeatedly
obtain data from each sensor of said plurality of sensors;
analyze said data to identify a heartbeat and a phase of a heartbeat cycle;
apply a sequence of tests to the data from said each sensor,
confirm that data from said each sensor of all of said plurality of sensors is consistent with said heartbeat and said phase of said heartbeat cycle, from said sequence of tests applied to the data; and,
when said sequence of tests applied to said data succeed, wherein said data from said each sensor of said plurality of sensors is consistent, and said phase of said heartbeat cycle is a safe time period for cardiac ablation, enable said pulse generator to generate said electrical pulses.
