Our objective in this study was to test the hypothesis that prolonged QTc dispersion predisposes to arrhythmias in electroconvulsive therapy (ECT).
We measured QTc dispersion on ECT patients' baseline ECG and also measured PVCs and PACs during and for two minutes after ECT seizures. Using Poisson regression analysis, we found that baseline QTc dispersion was positively associated with ictal and post ictal PVCs and with post ictal PACs.
We conclude that QTc dispersion appears to be a valid predictor of arrhythmias.
本研究的目的是检验以下假设，即长时间的QTc离散度易导致电休克治疗（ECT）中的心律失常。
我们在ECT患者的基线心电图上测量QTc离散度，并在ECT发作期间及发作后两分钟测量室性早搏（PVCs）和房性早搏（PACs）。使用泊松回归分析，我们发现基线QTc离散度与发作期及发作后室性早搏以及发作后房性早搏呈正相关。
我们得出结论，QTc离散度似乎是心律失常的有效预测指标。
