The electric fetal heart activity was firstly recorded as tiny deflections on maternal limb lead electrocardifogram (ECG) by Cremer [1], direct lead fetal ECG with needle electrode by Caldeyro-Barcia et al. [2] and with scalp lead clip electrode by Hon [3]. Indirect maternal abdominal lead fetal ECG (fECG) was recorded by Maeda and Nakano [4] and others. Intrapartum fetal heart rate (FHR) was m...

Introduction Prospective synchronization on living organisms of MRI acquisitions to reduce the motion artifacts involves the monitoring of both respiratory and heart motions in the thorax and abdominal region. The signal conventionally used to measure cardiac cycle is the electrocardiograph (ECG) signal. Respiratory motion can be derived from low frequency modulation of ECG signal [1]. Because ...

A new method based on least square support vector machine (LSSVM) combined with FastICA is proposed to extract the fetal electrocardiogram (FECG) from the abdominal signals of a pregnant woman. Firstly, the LSSVM is applied to estimate the maternal electrocardiogram (MECG) component in the multiplex abdominal signals. Then the optimal estimation of multiplex noise-added FECG is obtained by remo...

OBJECTIVES To evaluate the feasibility of dose-modulated retrospective ECG-gated thoracoabdominal aorta CT angiography (CTA) assessing abdominal aortic intimal flap motion and investigate the motion characteristics of intimal flap in acute aortic dissection (AAD). MATERIALS AND METHODS 49 patients who had thoracoabdominal aorta retrospective ECG-gated CTA scan were enrolled. 20 datasets were ...

introduction: it has been reported that cardiovascular effects are among the possible health effects of being exposed to extremely low frequency electromagnetic fields (elf emss). material and methods: this study has been conducted to evaluate the long term effects of exposure to magnetic and electric fields on electrocardiogram signal changes. nine power transmission posts having different vol...

A 57-year-old man had been followed up for severe left ventricular dysfunction after acute myocardial infarction with a left ventricular thrombus. He had been treated with anticoagulant and antiplatelet therapy and was admitted to our hospital because of abdominal pain and shock. He had no prior episode of trauma. The electrocardiogram (ECG) showed no changes compared with the previous ECG. Enh...

We present the case of a 20 year old man who presented to the emergency department of Craigavon Hospital with a one day history of abdominal pain and dyspnoea. He had been involved in a motorcycle accident three days previously and sustained a soft tissue injury to his left leg. Examination revealed lower abdominal tenderness and left calf swelling. Blood pressure was 140/53mmHg and oxygen satu...

A 74-year-old woman presented to hospital with dyspnoea of sudden onset. She was in cardiogenic shock, with blood pressure of 90/50 mmHg, and pulse rate of 115 bpm. The electrocardio-gram (ECG) was difficult to interpret because of severe, persistent and inexplicable artefacts (Box 1A). Chest x-ray showed acute pulmonary oedema thought secondary to left ventricular failure. Echocardiography sho...

ST-segment elevation is an important and alarming electrocardiographic sign that necessitates immediate attention but does not always indicate that the primary pathology is cardiac in origin. It needs to be interpreted in the clinical context as several pathological conditions involving especially gastrointestinal tract may lead to delayed diagnosis and treatment as well as complications from i...
