Background:Although the 12-lead electrocardiogram (ECG) has been found useful in identifying the left anterior descending (LAD) coronary artery as the infarct-related artery in acute myocardial infarction (MI), it has traditionally been felt to be incapable of localizing the culprit lesion within ...
Objective To predict the patients' infarct-related artery(IRA) site in acute anterior myocardial infarction(AhMI) with lead aVR.Methods All admitted patients underwent conventional electrocardiogram(ECG) and coronary angiography within 10 days.Among 89 patients who were diagnosed of AAMI,occlusion proxima...
Here is an example of an old anterior wall MI: Enlarge Note: To distinctly say that an old anterior wall MI is present on the ECG, there must be no identifiable R wave in lead V1 — and usually V2, as well. If there is an R wave in V1 or V2, the term...
ACE = angiotensin converting enzyme; AV = atrio-ventricular; ASMI = antero-septal myocardial infarction; AVR = aortic valve replacement; AWMI = anterior wall myocardial infarction; CABG = coronary artery bypass grafting; CT = computed tomography; ECG = electroca...
NOMI Paradigms of Acute MI 2021, Journal of Emergency Medicine Show abstract New Insights Into the Use of the 12-Lead Electrocardiogram for Diagnosing Acute Myocardial Infarction in the Emergency Department 2018, Canadian Journal of Cardiology Show abstract Incidence, angiographic features and outcomes ...
A comparison of seven ECG systems with 49-lead precordial maps, recorded from 20 patients with an acute anterior Q-wave myocardial infarction, was carried out. A total of 265 sets of ECG data recorded at predetermined time intervals from admission to discharge of the patients were utilized in...
All acute anterior wall MIpatients aged between 22 to 90 years of age, fulfilling the inclusion criteria , wereselected . Questionnaire was made to collect data. It included the history andclinical findings to study the complications of anterior wall MI. Clinical diagnosiswas made using ECG, ...
In 12 MI patients the QRS complex was within normal limits on standard 12-lead ECG (group A), and in 8 patients no pathologic Q waves were present but the R waves were small and did not normally increase from V 1 to V 4 (group B). In each subject instantaneous potential distributions...
anterior MI in the left ventricle quantified with both magnetic resonance imaging (MRI) and electrocardiogram (ECG).MethodsDelayed-enhancement (DE) MRI was used as a clinical "gold standard" for MI size to evaluate the extent of MI estimated with the commonly available standard 12-lead ECG. A...
Conclusion: In a population of anterior STEMI patients, persistent Q waves defined according to the classic ECG criteria after reperfusion was associated with a 4-fold increase in the risk of heart failure or death compared to non-Q-wave MI, while Q-wave regression was associated with ...
