Abstract:
Objective To analyze alterations in electrocardiogram (ECG) of adenosine test in 99Tcm-MIBI myocardial perfusion imaging(MPI)SPECT study. Methods A total of 641 patients were in cluded in the study. The patients each underwent 99Tcm-MIBI MPI with adenosine test. The ECGs were taken before, during, and after adenosine infusion. Results In all, abnormal ECGs were found in 205(32.0%) patients. During adenosine infusion, 20.6%(132/641) of patients suffered from arrhythmia,29.5%(39/132) had atrial premature beats, 34. 1% (45/132) had premature ventricular beats, and 6. 1% (8/132) had sinoatrial block. In addition, 5.3% (7/132) had first-, 24.2% (32/132) had second-, and 0.8%(1/132) had third-degree atrioventricular block (AVB). After adenosine infusion, 4.4%( 28/641) of patients suffered from arrhythmia, 57.1% (16/28) had atrial premature beats, 39.3%(11/28) had premature ventricular beats, and 3.6% (1/28) had sinoatrial block. The perfusion images showed ischemia in 36 patients and infarction in 8 patients. Adenosine infusion was terminated in 39 patients (6. 1%) because of poorly tolerated side effects. However, no death or acute myocardial infarction occurred in the study. Conclusions Adenosine pharmacologic test for 99TcmMIBI MPI may result in relatively high incidence of arrhythmia in ECG monitoring.
