Abstract
An implantable medical device and associated method assesses T-wave alternans. The method includes sensing a cardiac signal from implanted electrodes subsequent to a premature contraction; measuring a T-wave parameter from the sensed cardiac signal for a plurality of cardiac cycles; and determining a T-wave alternans metric corresponding to the measured T-wave parameter.
