A METHOD AND SYSTEM FOR VECTOR ANALYSIS OF ELECTROCARDIOGRAM IN ASSESSMENT OF RISK OF SUDDEN CARDIAC DEATH (SCD) DUE TO ARRHYTHMOGENIC RIGHT VENTRICULAR DYSPLASIA/CARDIOMYOPATHY BY QUANTIFYING MICRO SCARS (I.E. "BITES") IN THREE DIMENSIONAL VECTOR LOOPS

摘要

Subject matter of the invention are a method and a system to provide diagnosis of arrhythmogenic right ventricular dysplasia—ARVC/D (and similar inherited conditions) that cause sudden cardiac death in otherwise healthy population. Innovative approach in this analysis is possibility to detect so called frusta forms or clinically silent forms. After recording on any ECG standard device, vector analysis is manipulated in strictly defined fashion. The shape and size of QRS complex seen in arrhythmogenic right ventricular dysplasia/cardiomyopathy is determined by the direction and magnitude of the spatially oriented electrical forces that have one common beginning those concerning vector bites. Besides one pathognomonic place there is a triangle of dysplasia to look for. The subject matter of the invention greatly increases the sensitivity and specificity of standard ECG device for early detection with a high likelihood ratio of certainty for a positive diagnosis.

1. Method for vector analysis of electrocardiogram in the assessment of the risk of sudden cardiac death (SCD) due to arrhythmogenic right ventricular dysplasia/cardiomyopathy by quantifying micro scars (i.e. “bites”) in three dimensional vector loops, characterized in that it includes the following phases:
a) the first phase in which collecting information about the electrical activity of heart recorded on electrocardiogram (ECG) is performed by an unit for data collecting about the electrical activity of heart recorded on electrocardiogram (ECG); b) the second phase in which based on the collected data vectorcardiogram (VCG) is generated by an unit for generating vectorcardiogram (VCG) on the basis of collected data; c) the third phase in which the analysis of obtained vectorcardiogram due to arrhythmogenic right ventricular dysplasia/cardiomyopathy by quantifying micro scars (i.e. “bites”) in three dimensional vector loop, is performed by an unit for the analysis of obtained vectorcardiogram for the sake of estimating the existence of the risk of SCD by quantifying micro scars (i.e. “bites”) in three dimensional vector loop; and d) the fourth phase in which diagnostics ends and the result on whether the risk of SCD is established or not is issued, and the acquired result is optionally, together with personal and other diagnostic data about the patient, stored in a database for further use is performed by an unit in which on the basis of such diagnosis results are printed and issued out, providing basis on which the risk of SCD is established or not, and the subject finding is optionally, together with personal and other diagnostic data about the patient, stored in form of database for later use.
