electrocardiography

Examples of electrocardiography in the following topics:

• Work and Technology

  • Medical processes such as primary screening in electrocardiography or radiography and laboratory analysis of human genes, sera, cells, and tissues are carried out at much greater speed and accuracy by automated systems.

• Myocardial Ischemia and Infarction

  • Various forms of cardiac stress tests may be used to induce both symptoms and detect changes with electrocardiography (EKG), echocardiography (using ultrasound of the heart), or scintigraphy (using a radioactive marker to examine blood uptake by the heart muscle).

• Checking Circulation

  • For more accurate or long-term measurements, electrocardiography may be used.

• Medical Imaging

  • Measurement and recording techniques which are not primarily designed to produce images, such as electroencephalography (EEG), magnetoencephalography (MEG), electrocardiography (EKG), but which produce data susceptible to be represented as maps (i.e. containing positional information), can be seen as forms of medical imaging.
