Abstract:
Objective To investigate the cardiac affects of esophageal dilatation and stent implantation and its possible pathogenic mechanism. Methods One hundred patients who underwent esophageal dilation or stent implantation had investigeted with Hotter tape recorder, vectorcardiogram, oxygen saturation and cardiac enzymes checked at the time prior to. during and after the procedure respectively. Results During the procedure, incidence of frequent ventricular premature beats was 66%, paroxysmal ventricular tachycardia 9 cases; frequent atrial premature heats 73 cases, paroxysmal supraventricular tachycardia 21 eases, myocardial ischaemia 17 cases and hypoxia 69 eases with significant differences comparing with those prior to the procedure(9 cases; 0 case; 7 cases; 0 case; 0 case and 9 eases respectively) but all above changes as well as cardiac enzymes recorded 24 hours after the procedure had no statistical significance comparing with those prior to the procedure. Conclusion There is a high incidence of cardiac arrhythmia and myocardial ischaemia at the time of dilatation and stent implantation. However, most of these changes can subside without intervention 24 hours after the procedure. Pathogenic mechanisms involved may be related to hypoxia duo to the pain provoked by the procedure suggesting close observation is needed during the operation.
