Electrocardiogram Patterns Prevalence in Aging Male and Female Patients with Various Diseases Visiting the Electrocardiogram Unit of Federal Medical Center, Umuahia, Abia State
Abstract
Aging comes with its physiological changes and ECG abnormalities. The aim of this study is to examine the electrocardiography patterns prevalence amongst aging male and female individuals with various diseases visiting the electrocardiography unit of federal Medical center Umuahia, Abia state. 368 subjects were recruited for this study, The ECG of the subjects were recorded, and all the information of the patient and clinical presentations noted. The 12-lead ECG of was analyzed by subjecting it to Minnesota coding: Coronary probable (certainly diagnostic of myocardial infarction/coronary artery disease) included all those coded 1.1 and 1.2 (large Q and QS waves) and 7.1 (complete LBBB). Coronary possible (likely, but not certainly myocardial infarction eg angina pectoris) included those coded 1-3 (small Q- waves), 4-1, 4-2, 4-3 (S-T segment abnormalities), and 5-1, 5-2, and 5-3 (T-wave abnormalities). All other codings are regarded as normal. Another form of classification of “Ischaemic ECG” was defined as pathological Q waves (any Code 1); S-T segment and / or T wave inversion of any degree (any Code 7.1.1). Left ventricular hypertrophy (LVH) were defined as a combination of high voltage and either S-T segment depression or T-wave inversion, again on the basis of appropriate Minnesota Codes, but the former was used in this study. Statistical analysis was done using SPSS statistical windows version 16.0 (SPSS Inc, Chicago, IL, USA). The statistical association between males and females were considered significant whenever the p value was less than 0.05. From this present study, It was obvious that the subjects of this group 70 t0 100years of age have serious health condition, they at risk of cardiac sudden death, myocardial infarction and other related conditions. This is so because of the high prevalence of LVH 35%, conduction abnormalities 45%, T abnormalities 25% and leftward deviation 35%.
