Problems of validation and verification are very critical in medicine. The absence of adequate models describing biophysical processes in the organism leads to using only practical evidence for these purposes that hinders innovations. But advances in medicine require new effective ways to solve these problems. Cardiometry as a new field in cardiology offers a new philosophy of validation and verification based on the classical proof theory borrowed from natural sciences. The aim hereof is to provide a new methodology for validation and verification for cardiovascular diagnostics.
The paper presents some interesting data and findings on the study of the performance of the cardiovascular system in long-living individuals aged over 90. In this case, highland area individuals of this class are compared with those in flatland areas.
The article briefly discusses the cardiometric approach to the evaluation of metabolic processes in cardiac muscle. Reactions occurring during the various phases of the cardiac cycle, primarily in the QRS complex, are shown. The dynamics of energy processes occurring before and after physical load, as well as the reactions occurring during it, are presented. The ECG derivative is used.
