The ECG findings of an acute anterior myocardial infarction wall include: ST segment elevation in the anterior leads (V3 and V4) at the J point and sometimes in the septal or lateral leads, depending on the extent of the MI. This ST segment elevation is concave downwa...
The ECG findings of an old anterior myocardial infarction include: Loss of anterior forces leaving Q waves in leads V1 and V2. This is sometimes termed "poor R wave progression" or PRWP. Note: To distinctly say that an old anterior wall MI is present on the ECG, there must be no ide...
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, ...
We successfully terminated the PMAT, sparing MI conduction through distal ethanol infusion into the vein of Marshall (VOM), and achieved a complete conduction block at the AML. Case report An 80-year-old woman presented with recurrent palpitations. Electrocardiography (ECG) showed narrow QRS ...
Clinical significance of inferior ST elevation during acute anterior wall MI OBJECTIVES: To clarify the genesis and clinical significance of inferior ST elevation during acute anterior myocardial infarction. PATIENTS AND DESIGN: A t... A Tamura,H Kataoka,K Nagase,... - 《Br Heart J》 被引量:...
Objective:To explore the characteristics of coronary angiography and the safety and efficacy of primary percutaneous coronary intervention in patients with anterior wall acute myocardial infarction with "tombstoning" electrocardiographic(ECG) pattern.Method:The data of 102 patients who were underwent primary...
If the activation arrives first at the terminals of the posterior division of the LBB, the delayed excitation of the anterior and lateral wall of the left ventricle results in a leftward or superior shift of the QRS axis. If the activation front arrives first at the terminals of the ...
Ejection fraction and wall motion abnormality were also identical. Group A had higher complication rate (P<0.05) than group B. right ventricular (RV), lateral and posterior MI that influence the degree of ST segment depression were meaningfully different between these groups. RV infarction was ...
Selvester QRS scoring system has an advantage of being inexpensive and easily accessible for estimating myocardial infarct (MI) size. We assessed the correlation and agreement between QRS score and total perfusion deficit (TPD) calculated by quantitative gated single-photon emission computed tomography (...
After anesthesia the animal was shaved on the chest wall, and sono-gel was used. Under M-mode sonography the diameter of aortic outflow track and the size of left atrium were measured in long axis view of heart. Short axis M-mode at the level of the papillary muscle was used for ...
