New onset of electrocardiographic (ECG) abnormalities can occur after lung surgery due to the changes in the position of structures and organs in the chest cavity. The most common heart rhythm disorder is atrial fibrillation. So-called "pseudoischemic" ECG changes that mimic classic ECG signs of acute myocardial ischemia are also often noticed. We report the case of a 68-year-old male, with no ...

OBJECTIVE The prognostic importance of changes in ischaemic ECG abnormalities over time (especially ST-T abnormalities) among Asians has not been fully investigated. We examined the associations between changes in ischaemic abnormalities upon serial ECG (improvement, persistence, deterioration) and cardiovascular disease (CVD) risk. METHODS A prospective study cohort was conducted with 9374 m...

CONTEXT Electrocardiographic (ECG) abnormalities are common following subarachnoid hemorrhage (SAH). It probably represents cardiovascular stress after SAH. AIMS The purpose of this study was to assess cortisol dynamics in relation to the ECG abnormality and disease course of SAH. SETTINGS AND DESIGN The study follows a consecutive cohort of aneurysmal SAH patients, who underwent surgery wi...

OBJECTIVE To evaluate the clinical usefulness of complete preparticipation cardiovascular screening in a large cohort of sports participants. DESIGN Cross sectional study of data over a five year period. SETTING Institute of Sports Medicine in Florence, Italy. PARTICIPANTS 30,065 (23,570 men) people seeking to obtain clinical eligibility for competitive sports. MAIN OUTCOME MEASURES Res...

Torsades de pointes is a rare but potentially lethal arrhythmia which mainly occurs in the setting of a prolonged QT interval. ECG is a reliable tool to detect such abnormalities, routinely taken from all patients over 40 who undergo surgery. We describe the case of a 35-year-old woman with torsades de points arrhythmia after hysterectomy surgery. Most likely, our patients had long QT syndro...

INTRODUCTION AND OBJECTIVES The predictive value of ECG abnormalities in patients with type-2 diabetes mellitus (DM2) has not been fully studied. Our objective was to assess the prognostic value of ECG abnormalities in patients with DM2 but without known cardiovascular disease. METHODS Overall, 412 patients with DM2 were identified at two primary care centers in the same city. Two hundred and...

sis. It is doubtful that inadequate alpha-receptor blockade was a significant factor, since the blood pressure was well controlled with phenoxybenzamine. Although T wave changes may occur in patients with mitral valve prolapse9 (a condition suggested by this patient's initial physical examination), it seems unlikely that this would explain the close association between ECG changes and specific ...

BACKGROUND Most studies on risk factors for development of coronary heart disease (CHD) have been based on the clinical outcome of CHD. Our aim was to identify factors that could predict the development of ECG markers of CHD, such as abnormal Q/QS patterns, ST segment depression and T wave abnormalities, in 70-year-old men, irrespective of clinical outcome. METHODS Predictors for development ...

BACKGROUND In children, sudden cardiac arrest (SCA) is associated with structural and electrical cardiac abnormalities. No studies have systematically screened healthy school children in the United States for conditions leading to SCA to identify those at risk. METHODS From June 2006 to June 2007, we screened 400 healthy 5- to 19-year-olds (11.8 ± 3.9 years) in clinical offices at The Childre...

ECG contains very important clinical information about the cardiac activities of heart. The features of small variations in ECG signal with time-varying morphological characteristics needs to be extracted by signal processing method because there are not visible of graphical ECG signal. Small variations of simulated normal and noise corrupted ECG signal have been extracted using FFT and wavelet...
