The current issue of our journal has been published. Since the previous issue CARDIOMETRY has been making rapid strides. It is important to note that the journal’s papers have served not only the purpose of formulation of new scientific problems, but also the purpose of their solutions.

Familial arrhythmogenic right ventricular dysplasia in Afro-Caribbean: treadmill stress test the key to early diagnosis
Arrhythmogenic right ventricular dysplasia is a rare entity and a significant cause of sudden death especially in the Italian population and athletes. The familial form is uncommon especially in the Afro-Caribbean population.

There has been a significant interest in recent times in discussing how to properly interpret the diagnostic value of the point J on ECG. At first sight, it might appear to be a rather simple issue, but till now no consensus in its interpretation has been reached.

Linear Eсkman friction in the mechanism of the cyclone-anticyclone vortex asymmetry and in a new theory of rotating superfluid
The observed experimental and natural phenomenon of cyclone-anticyclone vortex asymmetry implies that a relatively more stable and showing a longer life, as well as a relatively more intense mode of rotation with an anticyclonic circulation direction (opposite to the direction of rotation of the medium as a whole) is realized as compared with an oppositely directed rotation of the cyclonic vortex mode. Until now, however, it was not a success to identify a universal triggering mechanism responsible for the formation of the corresponding breaking of chiral vortex symmetry.

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.

New philosophy of validation and verification for cardiology: classical proof theory imported from natural sciences
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.

Occurrence of HLA- and non-HLA antibodies after heart transplantation are associated with cardiac allograft vasculopathy
Cardiac allograft vasculopathy (CAV) accounts for major morbidity and mortality late in the heart transplant (HTx) history. The role of antibodies (Abs) directed against human leukocyte antigens (HLA) and non-HLA antigens in the pathogenesis of CAV are still under investigation.

Cardiometry: pioneering experience in assessment of the heart performance and evaluation of fatal arrhythmia risks in intensive care unit patients
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.
