MULTIPLE CHEST LEAD CARDIOGRAMS AND THEIR CLINICAL VALUE

The Clinical Value of Chest Leads.

In the growth of electrocardiography as a clinical method, British physiologists and physicians have played a more important role than those of any other nationality. Waller was the first to show that the electrical activities of the human heart could be recorded by leading from the extremities or from the surface of the chest. Mackenzie, although he did not deal directly with this subject, tre...

Clinical Value of Low Dose CT- Scan in Pediatric Chest Diseases: Adequacy Assessment

Background Radiation dose about 400 times that of standard thoracic computed tomography (CT) in comparison with chest X- ray resulting in different approaches to decrease radiation dose have been established in the last few years to prevent possible side effects especially in children, such as low dose protocols. The aim of this study was assessment of clinical v...

Clinical significance of synthesized posterior/right-sided chest lead electrocardiograms in patients with acute chest pain.

BACKGROUND 12-lead electrocardiograms (ECGs) provide insufficient information for the accurate diagnosis of posterior and/or right ventricular acute myocardial infarction (AMI) in patients with acute chest pain. Posterior chest leads (V7-V9) and/or right-sided precordial leads (V3R-V5R) provide important information from those specific areas, but these additional ECGs are not routinely recorded...
