上图是某试验筛选期收集的EG信息，ECG的检测指标主要有以下6个：PR Interval (PR)、QRS Interval (QRS)、QT Interval (QT)、QTc Interval (QTc)、RR Interval (RR)以及 Heart Rate (HR)。除了以上6个检测指标外，ECG Form还会包含 研究者对与检测结果的判定 ，具体是图中 Result Code 的...
因此,临床评价QT间期时,通常需要对其进行校正,最常采用Bazett’s法,即QTc=QT/RR。但在心率过快或过慢时,该校正法存在明显不足。有研究提出其他的校正方法,如Fridericia公式、Framingham公式以及Hodges公式等。 目前,尽管有少数研究比较不同的QT间期校...
QT interval 正常的QT时间间隔在0.33到0.44秒之间。这个时间间隔代表了心室去极化和复极化的总时间。QT间期的延长可导致危及生命的心律失常,称为尖点扭转。许多手术室常用药物和在PACU可导致QT延长。QT延长是在全身麻醉下接受非心脏手术的患者术后常见的表现,发生率为4%。
In14 features such as the R peak and RR interval were extracted using discrete-wavelet-transform (DWT), and multi-layer perceptron (MLP) was used in ECG classification. The obtained accuracy was \(99.9\%\) but a total number of 301 features were used for classification. Similarly, in15, ...
