目的：调查睡眠磨牙 (SB) 事件可以通过心率增加来预测的假设。材料和方法：招募了 14 名睡眠磨牙者。每个参与者使用便携式遥测系统连续 2 个晚上在家记录自己的肌电图 (EMG) 和心电图 (ECG)。分析SB事件发生前的10次心跳（B10至B1）和SB事件发生后的3次心跳（A1至A3），并确定预测SB事件的阈值。通过额外一晚以相同方式记录的肌电图和心电图来测试阈值的有效性。评估 SB 事件的预测准确性的敏感性和特异性。结果：在 SB 事件发生之前观察到心率逐渐增加，并且 B1、A1、A2 和 A3 显着高于 B10 (P < .01)。当记录的第二晚所有心率的平均值设置为100%时，阈值设置为110%。总共观察到 324 起 SB 事件，其中 299 起之前心率增加超过阈值（灵敏度，92.3%）。心率增加事件总数为1,239，阈值应用总数估计为120,000。特异性为99.2%。结论：超过 90% 的 SB 事件可以通过心率增加 110% 来预测。由于敏感性和特异性极高，因此可以通过心率增加来预测 SB 事件的假设得到了肯定的验证。
Purpose: To investigate the hypothesis that sleep bruxism (SB) events could be predicted by an increase in heart rate. Materials and Methods: Fourteen sleep bruxers were recruited. Each participant recorded his or her own electromyography (EMG) and electrocardiography (ECG) at home for 2 consecutive nights using a portable telemetry system. Ten heartbeats before (B10 to B1) and three heartbeats after (A1 to A3) the onset of SB events were analyzed, and the threshold for the prediction of an SB event was determined. The validity of the threshold was tested by EMG and ECG recorded in the same manner for an additional night. The prediction accuracy of SB events was evaluated for sensitivity and specificity. Results: A gradual increase in heart rate was observed before an SB event, and B1, A1, A2, and A3 were significantly higher than B10 (P < .01). The threshold value was set at 110% when the mean of all heart rates of the second night of recording was set at 100%. A total of 324 SB events were observed and 299 were preceded by increased heart rate that exceeded the threshold (sensitivity, 92.3%). The total number of increased heart rate events was 1,239, and the total number of threshold applications was estimated to be 120,000. The specificity was 99.2%. Conclusion: Over 90% of SB events could be predicted by an increasing heart rate of 110%. Since the sensitivity and specificity were extremely high, the hypothesis that SB events could be predicted by increased heart rate was positively verified.
