Clinical electrophysiology and electrocardiography: Summary

ABC of clinical electrocardiography: Paediatric electrocardiography.

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...

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 Ocular Electrophysiology

Clinical electrophysiology in myasthenia gravis.

Effective diagnostic methods are of great importance in order to recognise myasthenic patients among those with muscle fatigability. Intracellular recordings are useful for research work within the field and for detailed description of the motor end-plate's physiology in the individual case. The method is not used for the routine diagnosis of myasthenia gravis. The decrement of the electrical m...
