  of the Q wave is used for the diagnosis of new or previous MI [5]. Q waves are considered pathological when wider than 40 ms. in duration and have an amplitude greater than -0.2 mV. Despite general reliance on these ECG findings, there have been no recent studies to assess the predictive value of the Q waves in inferior leads for the
