2022年8月24日 · One of the biggest questions asked when considering a heart rate monitor is "what’s the difference between ECG and PPG?", quickly followed by "Which is the most accurate?" Read on to find out the answer to both of these questions.

️ According to the ESC guidelines, ECG is the golden standard for heart rate and rhythm assessment. PPG is increasingly gaining more evidence and popularity to be used in heart rhythm use cases. ️ ECG can be diagnostic, while PPG still requires a confirmatory ECG in patients without a prior AF diagnosis. In any case, clinical oversight is ...

2015年1月28日 · There are two primary technologies for measuring heart-rate metrics: ECG (electrocardiography) and PPG (photoplethysmography). When you download this side-by-side comparison, you’ll learn how the solutions stack up against one another.

心电描记术 (Electrocardiography, ECG或者EKG) 是一种经胸腔以时间为单位记录心脏的电生理活动，利用在人体皮肤表面贴上的电极，可以侦测到心脏的电位传动，而心电图所记录的并不是单一心室或心房细胞的电位变化，而是心脏整体的电位变化。 心电图的结果通常以波型显示，基本包括有P波、QRS波组、T波。 P波代表的是心房收缩，QRS波组则是心室收缩，T波是心室舒张。 …

2017年3月21日 · In order to measure the cardiac cycle and obtain heart rate measures, multiple sensor-based techniques exist. The two most widely used methods are electrocardiography (ECG, also known as EKG), and photoplethysmography (PPG).

PPG signals are an emerging non-invasive measurement technique used to study blood volume pulsations through the detection and analysis of the back-scattered optical radiation coming from the skin. ECG is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin.

2024年11月5日 · In order to enhance the quality of the reconstructed ECG signal, we propose an innovative hybrid attention-based bidirectional recurrent neural network (Bi-RNN) that incorporates a dilated convolutional neural network technique for the purpose of reconstructing ECG signals from PPG signals.
