Comparison of the new acceleration spectrum analysis with other time- and frequency-domain analyses of the signal-averaged electrocardiogram.
AIM To compare four analysis techniques of the signal-averaged-electrocardiogram, including time-domain, spectral temporal mapping, spectral turbulence analysis and the new acceleration spectrum analysis. METHODS AND RESULTS We studied 634 subjects (77 with bundle branch block) divided into three groups. Group 1 comprised 117 post-myocardial infarction patients tested for inducibility of sust...
متن کاملImproved diagnostic value of combined time and frequency domain analysis of the signal-averaged electrocardiogram after myocardial infarction.
BACKGROUND Time domain analysis (TD) of the signal-averaged electrocardiogram (SAECG) presents a higher incidence of false positives in inferior myocardial infarction (MI), whereas spectral turbulence analysis (STA) suffers from a higher incidence of false positives in anterior MI. We investigated the hypothesis that a combined TD and STA (TD+STA) analysis of the SAECG could improve its predict...
متن کاملSignal-averaged electrocardiography and detection of heart transplant rejection: comparison of time and frequency domain analyses.
To evaluate the role of the signal-averaged electrocardiogram (ECG) in the detection of heart transplant rejection, findings on 277 ECGs were compared with those in 218 endomyocardial biopsy specimens in 25 patients followed up for a median duration of 5.2 months (range 7 days to 17.5 months). Signal-averaged ECGs obtained at intervals of 16.4 +/- 22.3 days were analyzed in the time domain befo...
متن کاملAnalysis of the Relationship between the Business Cycle and Inflation Gap in Time-Frequency Domain
Controlling the business cycle and minimizing the inflation gap are considered as two major goals for monetary policy. Hence, the policymaker will be able to make more decisive decisions with an awareness of the dynamic relationship and causal relationship between these two variables. Accordingly, the present study uses a discrete and continuous wavelet transform to provide a new understanding ...
متن کاملReproducibility of the signal averaged P wave: time and frequency domain analysis.
OBJECTIVE To assess the reproducibility of time and frequency domain variables derived from the signal averaged P wave. DESIGN Longitudinal within patient study. SETTING Regional cardiothoracic centre. PATIENTS 20 patients (10 with documented paroxysmal atrial fibrillation and 10 normal controls) were studied on three occasions to assess the reproducibility of repeated signal averaged P w...
