Clinical significance of ambulatory electrocardiography

Lessons from ambulatory electrocardiography.

In the 1950s Norman "Jeff' Holter, the American physicist, developed and gave his name to the technique of recording physiological signals from ambulant patients.' Holter monitoring has now come to be synonymous with ambulatory electrocardiography. In hospital practice the term ECG (electrocardiogram) taping is used, often with the prefix 24 hours to indicate the usual duration of the record. A...

Ambulatory electrocardiography in car workers.

A previous study in a car assembly plant showed that production-line workers had a lower incidence rate of heart attacks than executive staff. In the present study some major coronary risk factors and 24-hour ambulatory electrocardiograms were investigated in two age-matched samples of 30 middle-aged men drawn from these occupations. Men with a known history of heart disease were excluded. Comp...

Clinical Significance of Upsloping ST Segments in Exercise Electrocardiography ROB

Conventional exercise electrocardiographic criteria usually involve patterns with a horizontal or downsloping ST segment. In the present study we present criteria based on upsloping ST segments and compared these criteria with the conventional criteria. Using upsloping ST-segment criteria, the amount of STsegment depression at 80 msec after the end of the QRS complex is used as a parameter (ST ...
