The EKG Sequence
The EKG or electrocardiogram sequence is defined by a(1) = 1, a(2) = 2 and, for n ≥ 3, a(n) is the smallest natural number not already in the sequence with the property that gcd{a(n − 1), a(n)} > 1. In spite of its erratic local behavior, which when plotted resembles an electrocardiogram, its global behavior appears quite regular. We conjecture that almost all a(n) satisfy the asymptotic formul...
متن کاملSystem for EKG Monitoring
In this paper the system for the electrocardiogram (EKG) monitoring based on the of Arduino microcontroller is presented. Detailed description of the electrocardiogram itself serves as a ground for building the proposed hardware and software solution. The software implementation is in a form of both, Mat-lab environment, and own application. Final output enables retrieval of the actual data in ...
متن کاملChaos Analysis for Ekg Time Series Data
Our project aims at testing various measures of chaos in time series data from an electrocardiogram (EKG). We examine data from three types of patients who we assume to produce varying EKG dynamics. We use time-delay embedding and calculate correlation dimensions to determine if the data is chaotic or random. Our results indicate that there is some evidence of deterministic chaotic behavior in ...
متن کاملEKG changes after spinal subarachnoid hemorrhage.
EKG Changes After Spinal Subarachnoid Hemorrhage • Marked morphological electrocardiographical changes occurred in a patient whose subarachnoid hemorrhage originated in the lower spinal canal. Thus, the electrocardiogram can show the changes well known for intracranial subarachnoid hemorrhage even when the source of bleeding is in the lower spinal canal. Additional
متن کاملDesign Illustration of an Ekg Analog Interface Using Genetic Algorithms
Electrocardiography (EKG) systems provide a solution for the recording of the heart activity and are indispensable in patient monitoring. Interfacing the EKG system with the human body is done with analog signal processing and operates towards proper signal conditioning. The EKG analog interface consists of an instrumentation amplifier, a notch filter and a highpass filter. This paper proposes ...
