| ambulatory electrocardiography | <investigation> An investigation, during which prolonged electrocardiographic recordings are made on a portable tape recorder (holter-type system) or solid-state device, while the patient undertakes normal daily activities. It measures the heart rhythm (ECG) over a 24 hour period while the patient records their symptoms and activities in a diary. After the test is complete, a correlation is made between the symptoms or activities recorded and the ECG pattern that was obtained simultaneously. It is useful in the diagnosis and management of intermittent cardiac arrhythmias and transient myocardial ischemia. (21 Jun 2000) |

| precordial | <anatomy, cardiology> Pertaining to the precordium, which is the region over the heart and lower part of the thorax. (18 Nov 1997) |
| precordial catch syndrome | <syndrome> A benign syndrome of uncertain origin, characterised by sharp, sudden pain in the region of the cardiac apex on inspiration, yet usually relieved by forcing a deeper breath; tenderness is absent. (05 Mar 2000) |
| precordial leads | Those in which the exploring electrode is on the chest overlying the heart or its vicinity. Synonym: precordial leads, semidirect leads. (05 Mar 2000) |
| electrocardiography | <procedure> The making of graphic records of the variations in electrical potential caused by electrical activity of the heart muscle and detected at the body surface, as a method for studying the action of the heart muscle. (18 Nov 1997) |
| foetal electrocardiography | Recording the electrocardiogram of the foetus in utero. (05 Mar 2000) |
