BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2012008087 DESCRIPTION Right ventricular (RV) myocardial infarction (MI) often accompanies inferior left ventricular (LV) MI. However, isolated RV MI is very rare. A man (age range 30–40 years) presented with acute chest pain. ECG revealed ST segment elevation in leads V1–V4 (fi...

Non-invasive recording of the late potential (LP) by signal-averaging technique is useful in predicting ventricular tachycardia (VT), especially in patients with myocardial infarction (MI). However, the rate of positive LP is LOW in anterior or anteroseptal MI, since the LP is masked by QRS complex. The purpose of the present study is first, to detect local conduction delay in initial portion o...

BACKGROUND Electrical storm (ES) due to drug refractory ventricular tachycardia (VT) occurring within first few weeks of acute myocardial infarction (MI) has poor prognosis. Catheter ablation has been proposed for treating VT occurring late after MI, but there is limited data on catheter ablation in VT within first few weeks of MI. METHODS AND RESULTS Five patients (4 males, mean age 54.2±12....

BACKGROUND The physiological mechanism of the increase in the electrocardiographic (ECG) R-wave voltage after revascularization in patients with acute myocardial infarction (MI) needs to be elucidated. METHODS AND RESULTS One hundred and thirty-eight MI patients (83: anterior MI, 45: inferior MI, 10: lateral MI) underwent ECG and echocardiography in both the acute and subacute phases after em...

In digital radiographic systems, a tradeoff exists between image resolution (or blur) and noise characteristics. An imaging system may only be superior in one image quality characteristic while being inferior to another in the other characteristic. In this work, a computer simulation model is presented that is to use mutual-information (MI) metric to examine tradeoff behavior between resolution...

OBJECTIVE To examine the use of reperfusion strategies in elderly patients with acute myocardial infarction (AMI) and investigate the factors affecting its use. METHODS This survey population consisted of 338 consecutive elderly patients with AMI (> or = 65 years) who were admitted to the department of cardiology of Beijing Military General Hospital between December 2003 and November 2007. Th...

AIMS The region-specific mechanical function of left ventricular (LV) murine cardiomyocytes and the role of phosphorylation and oxidative modifications of myofilament proteins were investigated in the process of post-myocardial infarction (MI) remodelling 10 weeks after ligation of the left anterior descending (LAD) coronary artery. METHODS AND RESULTS Permeabilized murine cardiomyocytes from...

The ability to review and analyze large amounts of data reliably and cost-effectively is important in both biomedical research and clinical care. We hypothesized that converting raw digital data to standard scores (Z scores) and gray-scale them based on their corresponding P values can be used to accomplish this. In Part 1 of the study, we recorded continuous digital electrocardiographic (ECG) ...

OBJECTIVES We sought to examine the determinants of exercise-induced changes in ischemic mitral regurgitation (MR) in patients with left ventricular (LV) dysfunction. BACKGROUND In the post-myocardial infarction (MI) phase, ischemic MR contributes to worsening of symptoms and of LV dysfunction. METHODS In this study, 70 patients in the chronic, post-MI phase, with LV ejection fraction <45% ...
