“…Various study groups have taken a different view as to whether the ST segment analysis of patients with initially reduced ST segment provides additional information. Some exclude these patients from the evaluation, whereas others include them and specify an ST depression of -0.1 or -0.2 mV in addition to the baseline ST depression [28]. The ST level that is recorded in a short time interval after the investigator had put the ECG electrodes in place, however, is designated as the baseline ST level.…”

ST depressions have a high prevalence of 20.1% in hypertensive patients. Clinical predictors for the occurrence of ST-segment depression were classical risk factors and cardiac target organ damage. Office-based blood pressure measurement was not a useful measuring tool for forecasting the likelihood of ST-segment depression. ST depressions were triggered inter alia by variations of blood pressure and the heart rate. The circadian variability of the ST depressions is crucially affected by the pressure double product characteristics on which the ST depression is based.

“…A previous study by Bjerregaard and colleagues showed that detecting ischemic events 80 ms after the J-point instead of 60 ms, used in this study, increased the number of ischemic events because most of these events are down-sloping 20. The inclusion criteria of 0.1 mV J-point depression will also reduce detected ischemic events.…”

“…The visual interpretation included the whole tape and parts of interest were printed out at 25 mm/sec speed for analyses of STDE and arrhythmia in relation to heart rate in order to identify possible positional ST changes, especially during night. ST segment changes was defined as >0.1 mV (1 mm) planar or down-sloping shift from the isoelectric baseline occurring at 60 milliseconds after the J point, with the midpoint of PR as a reference and with a duration of at least ≥1 minute 20. The maximal STDE was defined as the maximum value registered by the recorder.…”

ST segment depression (STDE) has been found to be associated with cardiovascular disease in the elderly. Studies of the relation of ambulatory STDE to cognitive function in elderly persons aged 80 years or above is lacking.Objective:To study the association between STDE and cognition.Design and participants:A cross-sectional cohort study of 88 81-year-old men from the population study “Men born in 1914” investigated in an outpatient research clinic. Measurements included ambulatory 24-hour electrocardiogram (ECG) monitoring and a cognitive test battery of six tests. Proportion of lower cognitive function was calculated for each test in relation to STDE during the day and at night-time.Results:Fifty-eight percent of the men had STDE and a higher proportion with low visuospatial cognitive function was found among those with STDE compared to the others (84% vs 59%; p = 0.014). A significant trend was noted for subjects without STDE compared to STDE night-time less than 60 minutes and night-time more than 60 minutes for spatial and verbal cognitive functions (p = 0.022). No trends were noted for STDE daytime. Maximal STDE during night showed similar association to spatial function (Benton Visual Retention test, r = −0.26; p = 0.028). Even when seven subjects with a history of stroke were excluded, the occurrence of STDE was associated to lower visuospatial cognitive function compared to those without STDE (87% vs 57%; p = 0.004).Conclusion:ST segment depression on ECG is common among elderly men and might be a vascular risk factor for cognitive deterioration.

“…The criteria for an ST-depression and ST-elevation were 0.1 mV flat or down-sloping morphology with deviated J-point. 10 Standard postoperative 12-lead ECGs were made on days 3, 7, and 30, and/or at discharge, and whenever clinically indicated.…”

ST Segment Analysis by Holter Monitoring:

Abstract: The outcome of Holter analysis for ischemic events is greatly dependent upon how an ischemic event is defined. Consensus on how to define an ischemic event is urgently needed.
