The Elliot wave principle commonly characterizes the impulsive and corrective wave trends for both financial market trends and electrocardiograms. The impulsive wave trends of electrocardiograms can annotate several wave components of heart-beats including pathological heartbeat waveforms. The stopping time inquires which ordinal element satisfies the assumed mathematical condition within a numerical set. The proposed work constitutes several algorithmic states in reinforcement learning from the stopping time decision, which determines the impulsive wave trends. Each proposed algorithmic state is applicable to any relevant algorithmic state in reinforcement learning with fully numerical explanations. Because commercial electrocardiographs still misinterpret myocardial infarctions from extraordinary electrocardiograms, a novel algorithm needs to be developed to evaluate myocardial infarctions. Moreover, differential diagnosis for right ventricle infarction is required to contraindicate a medication such as nitroglycerin.
The proposed work implements the stopping time theory to impulsive wave trend distribution. The searching process of the stopping time theory is equivalent to the actions toward algorithmic states in reinforcement learning. The state value from each algorithmic state represents the numerically deterministic annotated results from the impulsive wave trend distribution. The shape of the impulsive waveform is evaluated from the interoperable algorithmic states via least-first-power approximation and approximate entropy. The annotated electrocardiograms from the impulsive wave trend distribution utilize a structure of neural networks to approximate the isoelectric baseline amplitude value of the electrocardiograms, and detect the conditions of myocardial infarction. The annotated results from the impulsive wave trend distribution consist of another reinforcement learning environment for the evaluation of impulsive waveform direction.
The accuracy to discern myocardial infarction was found to be 99.2754% for the data from the comma-separated value format files, and 99.3579% for those containing representative beats. The clinical dataset included 276 electrocardiograms from the comma-separated value files and 623 representative beats.
Our study aims to support clinical interpretation on 12-channel electrocardiograms. The proposed work is suitable for a differential diagnosis under infarction in the right ventricle to avoid contraindicated medication during emergency. An impulsive waveform that is affected by myocardial infarction or the electrical direction of electrocardiography is represented as an inverse waveform.
艾略特波浪原理常用于描述金融市场趋势和心电图的脉冲和修正波趋势。心电图的脉冲波趋势可以注释心跳的几个波分量,包括病理性心跳波形。停止时间查询在数值集中的哪个序号元素满足假设的数学条件。拟议的工作从停止时间决策中构成强化学习的几个算法状态,该决策决定脉冲波趋势。每个提出的算法状态都适用于强化学习中的任何相关算法状态,并进行了全面的数值解释。由于商业心电图机仍然错误地解释了来自异常心电图的心肌梗死,因此需要开发一种新的算法来评估心肌梗死。此外,需要对右心室梗死进行鉴别诊断,以避免使用硝酸甘油等药物。
拟议的工作将停止时间理论应用于脉冲波趋势分布。停止时间理论的搜索过程相当于强化学习中的算法状态操作。每个算法状态的状态值表示从脉冲波趋势分布中数值确定的注释结果。通过最小一阶幂逼近和近似熵,从可互操作的算法状态评估脉冲波的形状。从脉冲波趋势分布中注释的心电图使用神经网络结构来近似心电图的等电基线幅度值,并检测心肌梗死的情况。脉冲波趋势分布的注释结果构成了另一个强化学习环境,用于评估脉冲波方向。
对于来自逗号分隔值格式文件的数据,区分心肌梗死的准确率为 99.2754%,对于包含代表性节拍的数据,准确率为 99.3579%。临床数据集包括 276 份来自逗号分隔值文件的心电图和 623 份代表性节拍。
我们的研究旨在支持 12 通道心电图的临床解释。拟议的工作适用于右心室梗死的鉴别诊断,以避免在紧急情况下使用禁忌药物。受心肌梗死或心电图电方向影响的脉冲波表示为反向波。
