Description: In this paper, a new approach in human identification
is investigated. For this purpose, a standard 12-lead electrocardiogram
(ECG) recorded during rest is used. Selected features
extracted from the ECG are used to identify a person in a predetermined
group. Multivariate analysis is used for the identification
task.

Description: The early detection of arrhythmia is very important
for the cardiac patients. This done by analyzing the
electrocardiogram (ECG) signals and extracting some features
from them. These features can be used in the classification of
different types of arrhythmias. In this paper, we present three
different algorithms of features extraction: Fourier transform
(FFT), Autoregressive modeling (AR), and Principal Component
Analysis (PCA). The used classifier will be Artificial Neural
Networks (ANN). We observed that the system that depends on
the PCA features give the highest accuracy. The proposed
techniques deal with the whole 3 second intervals of the training
and testing data. We reached the accuracy of 92.7083
compared to 84.4 for the reference that work on a similar
data.-The early detection of arrhythmia is very important

Description: This paper describe the features extraction algorithm for electrocardiogram (ECG) signal using Huang Hilbert Transform and Wavelet Transform. ECG signal for an individual human being is different due to unique heart structure. The purpose of feature extraction of ECG signal would allow successful abnormality detection and efficient prognosis due to heart disorder. Some major important features will be extracted ECG signals such as amplitude, duration, pre-gradient, post-gradient and so on. Therefore, we need a strong mathematical model to extract such useful parameter. Here an adaptive mathematical analysis model is Hilbert-Huang transform (HHT). This new approach, the Hilbert-Huang transform, is implemented to analyze the non-linear and nonstationary data. It is unique and different the existing methods of data analysis and does not require an a priori functional basis. The effectiveness of the proposed scheme is verified through the simulation.-This paper describe the features extraction algorithm for electrocardiogram (ECG) signal using Huang Hilbert Transform and Wavelet Transform.

Description: heart rate produced by algorithms embedded in the commercially
available optical heart rate sensor. An analysis of the raw PPG signal is
necessary to fully assess the usability of PPG for heart rate detection in
epilepsy, for instance, by also including measures for heart rate variability.
Mean heart rate is a suitable measure to detect tachycardia,
bradycardia, and asystole, which are importantmarkers of clinical relevance
of seizures. However, in other medical settings, such as the uation
of arrhythmias [10], more features of heart rate and ECG
characteristics such as QT interval,which PPG currently cannot provide,
are necessary for proper monitoring. Measurements in other patient
groups are necessary-heart rate produced by algorithms embedded in the commercially
