Abstract

Aim of the study was to compare the sensitivity and specificity of the ECG sign of myocardial necrosis – sequel Q, by using MPI SPECT study findings as a gold standard. All patients included in the study had fixed perfusion defect on the MPI SPECT study. We analyzed patients characteristics: gender, age, presence of significant Q wave on ECG (determined as >40 msec length and amplitude of >1/3 of accompanying R wave), present in at least two consecutive ECG leads, presence of fixed perfusion defect on MPI SPECT study, corresponding to the vascular territory. Data collection was made from patients medical records, ECG recording, and MPI SPECT study performed as one day rest/stress ECG gated study with Tc99m sestamibi, using Dipyridamole as vasodilating stressor. Significant Q-wave was recorded in 13 (41.9%) subjects, 5 in ECG leads corresponding to the inferior wall, 4 to the anterior wall, 3 both the inferior and the anterior wall, and 1 in the inferolateral wall. Only 41.9% of patients with myocardial infarction (detected with MPI SPECT study), had ECG sign of sequela, which indicates that ECG signs of myocardial scaring as a result of myocardial infarction are quite insensitive, as proven with concomitant performing of MPI SPECT study.
