Opinion has oscillated in the cardiology community regarding the significance of ventricular premature beats and non-sustained ventricular tachycardia as predictors of sudden cardiac death. Automaticity can be a marker of underlying structural heart disease. It is unclear whether the apparent association with sudden death is simply a reflection of this fact. Older data are unreliable as the populations studied probably had a high prevalence of unrecognized structural heart disease. Current risk stratification is imperfect. The balance of evidence suggests that automaticity does predict risk and it may have a role in risk-assessment algorithms, but at present the dataset is insufficient.
在心脏病学界，对于室性早搏和非持续性室性心动过速作为心源性猝死预测因子的意义，意见存在分歧。自动节律性可能是潜在结构性心脏病的一个标志物。目前尚不清楚与心源性猝死的明显关联是否仅仅反映了这一事实。早期的数据不可靠，因为研究人群可能存在大量未被识别的结构性心脏病。目前的风险分层并不完善。现有证据表明，自动节律性确实可以预测风险，它可能在风险评估算法中发挥作用，但目前数据集还不足够。
