“…QT intervals and Tpeak-Tend intervals were prolonged in post-infarction HF patients with LVPs. LVPs and SAECG parameters can be predicted using 12-lead ECG: QT intervals, QRS duration, T wave variables (Mozos et al, 2011). The significant association between SA-QRS and Tpeak-Tend interval and T wave amplitude was attributed to the extension of LVP into the ST segment.…”

“…In testing for the heart disease, the doctor will check blood pressure (https:// www.nia.nih.gov/health/high-blood-pressure) and do a fasting blood test to check cholesterol, a type of fatty substance that can contribute to plaques in the arteries. Blood test may also be carried out to check patients [5]. The initial ECG and CK levels in patients with STEMI may contain valuable information for risk stratification, determination of prognosis and the subsequent management plan [6].…”

Human heart is a strong muscle that pumps blood to the body. A normal, healthy adult heart is about the size of human clenched fist and it is like an engine that makes a car works, moves and functions properly as such, the heart keeps the body running. A healthy heart supplies the body with just the right amount of blood at the right rate for whatever the body is doing at that time. The flow of blood to the heart could be reduced by plaque build-up or blockage by a plaque suddenly ruptures, these could cause angina (chest pain or discomfort) or a heart attack. When the heart muscle does not get enough oxygen and blood nutrients, the heart muscle cells will die (heart attack) and weaken the heart, diminishing its ability to pump blood to the rest of the body. Remark that, if one is observing some unusual feeling in the heart, chest or in some related areas, this could result to carrying out an Electrocardiogram (ECG) test or examination. In this study, six factors (Sex, Weight, Height, Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and Heart Rate (HR)) were considered and investigated using factorial experiments to see those main effect(s) and interaction effect(s) that are significant in determining the activities of PR-interval in Electrocardiogram examination. The effect of Sex is the most significant of all the treatment effects considered, followed by the effects of Height and HR, while other factors were shown to have very little effect. Hence, it could be concluded that Sex, Height and HR are the most important factors influencing PR Interval in the ECG examination in order to evaluate the metabolic disorders, effects and side effects of pharmacotherapy, and the evaluation of primary and secondary cardiomyopathic processes, among others.

“…VLPs appear as fractioned signals with irregularity in shape on the body surface. From the studies in clinical cardiology, it has been shows that the occurrence of VLP is prevalent in post Myocardial Infarction (MI) patients at risk of developing Ventricular Tachycardia which is one of the leading causes of sudden cardiac death (Mozus et al, 2011).…”

Problem statement: Ventricular Late Potentials (VLPs) are low-level high frequency signals that are usually found within the terminal part of the QRS complex from patients after myocardial infarction. Patients with VLPs are at risk of developing ventricular tachycardia, which is the major cause of death if patients suffering from heart disease. Approach: Discrete Wavelet Transform was used to detect VLPs and then ANT Colony Optimization (ACO) was applied to classify subjects with and without VLPs. Results: A set of Discrete Wavelet Transform (DWT) coefficients was selected from the wavelet decomposition. Three standard parameters of VLPs such as QRST, D₄₀ and V₄₀ were established. After that a novel clustering algorithm based on Ant Colony Optimization was developed for classifying arrhythmia types. Conclusion: The wavelet decomposition enabled us to perform the task efficiently and produced reliable results
