About 20% of humerus fractures need a surgical treatment. Surgical options include closed reduction and percutaneous fixation, open reduction and internal fixation and prosthetic arthroplasty [1]. Recent studies have shown high failure rates after fixation of proximal humerus fractures with a range of 8.6% to 22%. Accordingly, loss of reduction and screw cut-out are the most common reasons for a revision...
Some factors that have increased cardiovascular incidents are sedentary lifestyle, poor eating habits, smoking, stress; hence the importance of continuously monitor cardiac activity in people. This research proposes the implementation of a wireless system to monitor the heart allowing visualization of the electrocardiogram (ECG) on a mobile device via Bluetooth (BT) technology and Arduino UNO board...
Every hour 8 to 10 Mexicans die because of cardiovascular diseases. The most common pathology is Myocardial Infarction, primarily responsible for deaths throughout of the country, and the leading cause of death in the Baja California state. Those who survive a myocardial infarction are highly likely to suffer Sudden Cardiac Death (SCD) due to the development of malignant ventricular tachycardia. This...
A digital image processing method for detecting tuberculosis (TB) is presented. First, a reference representing the specialists' determination of TB bacilli on a digital image is validated. And the noise in the signal intensities is evaluated to quantify the image capture system. A simple algorithm is proposed for identification of the bacillus, by means of only thresholding in the color channels...
Reduced heart rate variability (HRV) allows determining a decrease in the cardiac autonomic function. This has been associated with environmental pollution, especially with particulate matter smaller than 10 microns (PM10), carbon monoxide (CO) and ozone (O3) [1]. We examined the relationship between those pollutants and some parameters of the HRV in time and frequency domains. Intervals of 5 minutes...
This document presents a method for coupling and recording of signals from an electrocardiogram (ECG) and three electronic stethoscopes, as well as for the synchronized graphic display of the ECG and phonocardiogram (PCG) signals. This tool presents a visualization interface that assists teaching of the cardiac cycle and can be of support in non-invasive diagnosis of the heart. Low cost ECG and EE...
