Assessment of the diagnostic value of 24-hour ambulatory electrocardiographic monitoring. 1980

D E Ward, and A J Camm, and N Darby

During the 1st year of operation of a national 24-hour ambulatory ECG-monitoring service, 531 recordings were collected. The information from these recordings and accompanying patient diaries were classified according to the indication for monitoring, the presence or absence of the 'indicated' sympton or other symptom in the diary and the presence or absence of correlating arrhythmias on the tape. On the basis of this categorization 7.5% of recordings were considered completely diagnostic (indicated symptom noted in diary with correlating arrhythmias). An additional 26.6% or recordings, although not completely diagnostic, were considered clinically useful in that they provided information regarding the relationship of symptoms to arrhythmias or the presence or absence of arrhythmias. Major causes of loss of information were poorly completed diaries or no diary, lack of precise definition of the indication for monitoring and technical faults resulting in uninterpretable recordings. Rectification of these deficiences could improve the efficiency of data collection and analysis.

UI	MeSH Term	Description	Entries
D008991	Monitoring, Physiologic	The continuous measurement of physiological processes, blood pressure, heart rate, renal output, reflexes, respiration, etc., in a patient or experimental animal; includes pharmacologic monitoring, the measurement of administered drugs or their metabolites in the blood, tissues, or urine.	Patient Monitoring,Monitoring, Physiological,Physiologic Monitoring,Monitoring, Patient,Physiological Monitoring
D004244	Dizziness	An imprecise term which may refer to a sense of spatial disorientation, motion of the environment, or lightheadedness.	Lightheadedness,Orthostasis,Dizzyness,Light-Headedness,Light Headedness
D004562	Electrocardiography	Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.	12-Lead ECG,12-Lead EKG,12-Lead Electrocardiography,Cardiography,ECG,EKG,Electrocardiogram,Electrocardiograph,12 Lead ECG,12 Lead EKG,12 Lead Electrocardiography,12-Lead ECGs,12-Lead EKGs,12-Lead Electrocardiographies,Cardiographies,ECG, 12-Lead,EKG, 12-Lead,Electrocardiograms,Electrocardiographies, 12-Lead,Electrocardiographs,Electrocardiography, 12-Lead

D000553	Ambulatory Care	Health care services provided to patients on an ambulatory basis, rather than by admission to a hospital or other health care facility.

D001145	Arrhythmias, Cardiac	Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction.

D013575	Syncope	A transient loss of consciousness and postural tone caused by diminished blood flow to the brain (i.e., BRAIN ISCHEMIA). Presyncope refers to the sensation of lightheadedness and loss of strength that precedes a syncopal event or accompanies an incomplete syncope.
