Claim 10:
11. A computing device comprising:
communication circuitry configured to receive a cardiac signal from an insertable cardiac monitor having a cover, a plurality of electrodes, at least one of the plurality of electrodes being disposed on a proximal portion of the cover and at least another one of the plurality of electrodes being disposed on a distal portion of the cover, and sensing circuitry configured to sense the cardiac signal based on electrical activity of a heart of a patient via the plurality of electrodes; and
processing circuitry configured to:
determine an R-wave of the cardiac signal;
determine one or more RR intervals, wherein the one or more RR intervals comprise a previous RR interval associated with the determined R-wave and a current RR interval associated with the determined R-wave;
determine a search window for a T-wave of the cardiac signal based on the one or more RR intervals of the cardiac signal;
determine the T-wave in the search window;
determine at least one of a QT interval or a QTc interval based on the determined T-wave and the determined R-wave; and
at least one of predict or detect an abnormal cardiac rhythm based at least in part on the at least one of the QT interval or the corrected QT interval.
