Fetal heart rate estimated from fetal electrocardiogram (fECG), recorded via electrodes placed on the maternal abdomen, represents an important tool in evaluating fetal distress and diagnosing fetal diseases. However, due to poor signal to noise ratio (SNR) of the fECG, the abdominal fECG analysis is still very difficult, despite of significant advances in technology and in the field of electro...

Multidetector computed tomography has been shown to be accurate in noninvasive assessment of chest vascular disease. The motion artifacts of the thoracic aorta and the supra-aortic vessels were significantly reduced in the electrocardiogram (ECG)-gated data acquisition. This positive effect of ECG synchronization is more pronounced in the region of the ascending aorta, aortic arch, and proximal...

Objective Fetal endoscopic tracheal occlusion (FETO) has been reported to be beneficial to patients with congenital diaphragmatic hernia (CDH). It needs highly invasive procedures for balloon removal (fetoscopic and/or ultrasound-guided), and carries a given risk for both mother and fetus. We have reported the potential usefulness of high-intensity focused ultrasound (HIFU) as a noninvasive ext...

ultislice computed tomography (MSCT) coronary aniography (CA) has emerged as a powerful noninvasive iagnostic modality to visualize the coronary arteries and the anifestations of coronary atherosclerosis (1). Many reports ave demonstrated that 64-slice computed tomography CT) CA is a viable diagnostic modality to detect or rule out he presence of significant coronary stenoses, but the precise o...

Clinical examination, electrocardiogram and skiagram of chest have very low sensitivity in evaluation of pericardial diseases. Echocardiography has high sensitivity and specificity in evaluation of various pericardial diseases. Low cost and widespread availability make it the most useful noninvasive investigation for initial evaluation. Merits and limitations of echocardiography and it’s status...

Patients with cardiac arrhythmias may come to the attention of their physicians in a variety of ways. An asymptomatic arrhythmia may be fortuitously discovered on a routine electrocardiogram (ECG) or physical exam. Alternatively, a patient may present with a complaint suggestive of arrhythmia, usually palpitations, syncope, or presyncope. Finally, patients who have no history of arrhythmia, but...

Fetal Electrocardiogram (FECG) can provide important clinical information for the assessment of fetal well-being. However, the extraction of FECG from the maternal abdominal wall remains an open problem due to various kinds of interferences and noises, where the maternal Electrocardiogram (MECG) is the dominant source of interference. In this study, a novel FECG extraction framework by combinin...

Syncope is a common clinical presentation. Although most commonly benign, it may herald a pathology with a poor prognosis. The work-up of syncope includes a careful history, physical examination, electrocardiogram, risk stratification, and appropriately directed testing. The key factor in the investigation of syncope is the presence (or absence) of structural heart disease or an abnormal electr...

A proprietary, commercial technique has been proposed by its inventor as a noninvasive method of detecting subtle electrocardiogram abnormalities, not apparent by conventional means. To study the ability of the omnicardiogram to detect latent coronary heart disease in an asymptomatic population, 200 normal electrocardiograms from the Framingham Study cohort were analyzed by this technique. One-...
