ECG periodic table: a new ECG classification based on heart cycle phase analysis

Self Cite

The phase characteristics of a rheogram are described in literature in general only. The existing theory of impedance rheography is based on an analysis of the form of rheogram envelopes, but not on the phase-related processes and their interpretation according to the applicable laws of physics. The aim of the present paper is to describe the phase-related characteristics of a rheogram of the ascending aorta. The method of the heart cycle phase analysis has been used for this purpose. By synchronizing an ECG of the aorta and a rheogram, an analysis of specific changes in the aorta blood filling in each phase is provided. As a result, the phase changes of a rheogram associated with the ECG phase structure are described and tabulated for first time.The author hereof offers his own original classification of the phase-related changes of rheograms.

Conventional methods for arterial pressure (AP) measurement are not capable of identifying it in each cardiac cycle. Besides, they ignore many significant factors. The paper reports on an innovative method based on cardiac cycle phase analysis for detecting systolic and diastolic AP changes in each cardiac cycle using synchronous digitally processed ECG and Rheo recordings. Considered is the phase mechanism of the natural diastolic pressure regulation. The diastolic AP changes referred to the physiological norm and aortic dilatation status are also assessed.

“…The PC-assisted hemodynamic analyzer Cardiocode is designed for the electrocardiogram (ECG) recording in one lead with the synchronous rheogram (Rheo) recording and automatic calculation of the cardiovascular system hemodynamic parameters using phase durations and qualitative evaluation of the given parameters [4][5][6][7][8]. The severity of a patient state is evaluated according to the NIHA scale, and the prognosis is assessed according to the GRASE scale.…”

In the paper presented is an application study of the heart performance phase mechanism with the use of the Cardiocode analyzer based on principles of cardiometry for evaluating iatrogenic complications caused by antiarrhythmic therapy and monitoring the quality of treatment of hemodynamic disorders in inhospital intensive care units. The aim of the study is a thorough estimation of the diagnostic and functional quality of the performance of the Cardiocode device and developing a new methodology of its application under the conditions of the intensive care units, when predicting fatal arrhythmia progression. 50 patients with true cardiogenic shock of different degrees of severity have been examined with Cardiocode. As a result, it is established that the application of the heart cycle phase analysis in diagnostics, hemodynamics evaluation and management with the medication and infusion therapy supported by the Cardiocode device allows reducing the mortality rate by 32 ± 3.4 %.
