This protocol describes a method for calculating Heart Rate Variability (HRV) from electrocardiogram (ECG) waveforms. Waveforms from continuous heart rate (HR) recordings during active video game (AVG) sessions were used to measure the aerobic performance of youth with cerebral palsy (CP).Abstract...
will determine how long it takes for the electromagnetic pulse to travel through the heart by calculating time intervals on the ECG. Whether the electrical activity is natural or sluggish, fast or erratic, figuring out how long a pulse takes to travel from one part of the heart to the next...
in the digital ECG signals; the R-wave detection module is used for obtaining the RR interval according to the preprocessed lead II signals; the calculation module is used for calculating the heart rate according to the RR interval; the output module is used for outputting the heart rate. The...
ECG+ integrates with Apple Health to unleash the greatest power of your Apple Watch ECG, by analyzing and calculating intervals like QT/QTc, PR or QRS, and heart rate variability (HRV) out of your ECG data. QT/QTc are critical measurements linked to life-threatening arrhythmias. HRV is wide...
ECG sensors don’t require long settling times, so meaningful readings can be obtained very shortly after start-up. PPG sensors require a relatively long settling time due to the need for measuring the amount of ambient light and calculating the compensation needed for cancelling its effect. PPG...
Electrocardiogram (ECG) signals represent the electrical activity of the human hearts and consist of several waveforms (P, QRS, and T). The duration and shape of each waveform and the distances between different peaks are used to diagnose heart diseases.

A higher learning rate value produces a worse loss value and may cause skipping of the global minimum point. However, a smaller learning rate value increases the training time and may cause the model to fall into a local minimum. Optimizer: after calculating the loss value by the loss ...
(ECG or EKG) refers to a recording of the heart's electrical activity, and it can be used to help detect or diagnose some cardiac problems. During an electrocardiogram, electrodes are places on specific sites on the chest, and these electrodes detect the...
