Manini, MD, from Harvard Medical School in Boston, Massachusetts, and colleagues."Cardiovascular adverse effects can occur, including hypertension, arrhythmias, prolongation of the QT interval, and angina pectoris. Dangers of over-the-counter sympathomimetic use are illustrated by the recent ban on dietary supplements containing ephedrine alkaloids by the US Food and Drug Administration because of increased risk of sudden death, acute myocardial infarction, and stroke."

Manini医师表示，Pseudoephedrine是ephedrine的镜面异构物，会产生肾上腺素的综合促效作用，一般被用来作为解充血剂；此药的副作用包含高血压、心律不整、心电图QT波间距延长及心绞痛等；最近，美国食品药物检验局规定添加剂不得含ephedrine生物碱，由此可看出仿交感神经作用的药物所潜藏的危险；这些危险包含猝死、急性心肌梗塞及中风等。

According to the theory of wavelet transformation, the singularities of the ECG signal are corresponding to the series of maximum-minimum pairs. The algorithm detects the onsets of Q wave at the scale 3 detail and offsets of T wave at the scale 4 detail. So the duration of QT is calculated by onset of Q wave and offset of T wave.

根据小波变换的原理，心电中的奇异点在变换后将产生一个模极大值和模极小值对，在小波变换3尺度上检测出QRS波群的起点，在小波变换4尺度上检测出T波终点，从而确定QT间期。

Background Long QT syndrome is a cardiovascular disease that causes syncope, seizure, and sudden death from cardiac arrhythmias, such as torsade de pointes, and ventricular fibrillation.
