[Value of metabolic studies in diagnosis of ischemic cardiopathy].
10 patients with documented heart disease were undergone to atrial pacing (AP) combined to metabolic study. A negative lactate utilization (-%L) noticed in SC (coronary synus) represents a sure proof of a subordinate pacing ischaemia. As the negative lactate utilization is absent a significative reduction of %L during AP or its persistence in recovery and a rise of L/P are further parameters of a subordinate pacing ischaemia. The Authors consider the usefulness of combining a metabolic study to AP in assessing the RC (coronary reserve).
