Complementary Equipment for Computer Electrocardiography

The effect of a hostile ecological environment on the entire human body and its separate organs and systems is currently being comprehensively studied. To elucidate this problem, being new methods and equipment are necessary. In particular, much attention is being given to computer electrocardiography. Below, an attachment for a commercial single-channel electrocardiograph intended for the transfer of cardiosignals to a computer for the analysis of electrocardiograms by digital methods is presented. The significant extension of the capabilities of the electrocardiograph for earlier disease diagnostics is described

HIGH DEFINITION ECG: FROM PRESENT TO FUTURE

The study was aimed at assessing qualitative characteristics of late ventricular potentials (LVP) in 104 patients with various clinical forms of coronary heart disease (CHD). LVP assessment was performed at Days 3, 7, and 14 after admission to the acute cardiac care unit. The control group included 49 relatively healthy volunteers. For the majority of LVP and LVP spectre records, the amplitudes were consistent with the Gaussian random distribution. In addition, short and long-term dynamics of LVP parameters was investigated, after calculation of wavelet spectre and complex spectre module for each signal. To identify the high-correlation frequencies for paired leads, the cross-wavelet LVP analysis was used

High-definition electrocardiography potential in identifying the reasons for unstable clinical course of coronary heart disease

Aim. To investigate the correlation between clinical and morphological characteristics of coronary heart disease (CHD) and high-definition electrocardiography (HD-ECG) parameters. Material and methods. In total, 85 patients with unstable angina and ST segment depression (ST-UA) underwent HD-ECG during the angina attack, with late ventricular potential (LVP) analysis. One-year survival data were also analysed. Post-mortem histological examination of cardiac tissue was performed in 6 patients with ST-UA. Results. The important morphologic features of ST-UA included cardiomyocyte (CMC) dystrophy, due to acute and chronic myocardial ischemia, and acute injury in the cardiac conduction areas. LVPs were registered in 27 % of the ST-UA patients, mostly among people with transient myocardial ischemia (69,57 %). In patients who previ-ously underwent myocardial infarction, LVP prevalence was lower (28,57 %). At the early stages of hospitalization, LVP were registered in 14 patients (60,87 %), while pharmacotherapy and clinical course stabilization were associated with decreased LVP prevalence (21,74 %). The study results suggest that in patients with acute coronary syndrome, LVP registration predicts not an adverse outcome, but a better prognosis. Conclusion. ST-UA is characterised by typical changes of CMC and myocardial stroma in posterior septal area, which result in metabolic, energetic, and electrical myocardial instability. LVPs could be used as a marker of functional (ischemic) myocardial heterogeneity in patients with ST-UA. LVP registration could be associated with a better prognosis in this clinical group
