Electrocardiography in clinical practice

ABC of clinical electrocardiography: Paediatric electrocardiography.

Clinical and economic impact of exercise electrocardiography and exercise echocardiography in clinical practice.

BACKGROUND Patients with known or suspected coronary disease are often investigated to facilitate risk assessment. We sought to examine the cost-effectiveness of strategies based on exercise echocardiography and exercise electrocardiography. METHODS AND RESULTS We studied 7656 patients undergoing exercise testing; of whom half underwent exercise echocardiography. Risk was defined with the Duk...

Chest Leads in Clinical Electrocardiography.

In a previous communication Sorsky and Wood (1937) presented the normal appearances of chest lead electrocardiograms, paying particular attention to normal variations and to the position of the proximal electrode. As the question of standardizing the technique for chest leads was then under consideration by the Cardiac Society of Great Britain and Ireland and the American Heart Association, fur...

Clinical Fetal Electrocardiography *

Interest in clinical fetal electrocardiography dates back to 1906 when Cremer4 published two tracings apparently showing fetal deflections of about 0.5 mm. amplitude superimposed on the maternal electrocardiogram of a nine-months gravid woman. The records were obtained with a string galvanometer electrocardiograph with one lead on the abdomen and one in the vagina. During the next 25 years Foa7...
