INTRODUCTION Correct identification of the J-Point and ST-segment on an electrocardiograph (ECG) is an important clinical skill for paramedics working in acute healthcare settings. The skill of ECG analysis and interpretation is known to be challenging to learn and often is a difficult concept to teach. OBJECTIVES The objective of the study was to determine if undergraduate paramedic students...
Characteristic intraeavitary electrocardiographic conmplexes at various sites within the heart in normal individuals have been described previously. The intracardiac tracings in 150 eatheterizations, 129 of which were abnormal hearts, predominantly congenital defects, were studied in relationship to the position within the heart as determined fluoroscopically. In our experience, the tracings re...
A number of methods for temporal alignment, feature extraction and clustering of electrocardiographic signals are proposed. The ultimate aim of the paper is to find a method to automatically reduce the quantity of beats to examine in a long-term electrocardiographic signal, known as Holter signal, without loss of valuable information for the diagnosis. These signals include thousands of beats a...
This report describes an electrocardiograph (ECG) processor for use with a wearable healthcare system. It comprises an analog front end, a 12-bit ADC, a robust Instantaneous Heart Rate (IHR) monitor, a 32-bit Cortex-M0 core, and 64 Kbyte Ferroelectric Random Access Memory (FeRAM). The IHR monitor uses a short-term autocorrelation (STAC) algorithm to improve the heart-rate detection accuracy des...
