Purpose Of The Study: To analyze a correlation between sino-atrial node automatic activity and atrio-ventricular conductivity in patients with lower acute myocardial infarction (AMI) and atrio-ventricular blockade II-III (AVB) during infusion therapy.
Materials And Methods: Retrospective analysis of care for patients with AMI and AVB was carried out. Infusion therapy effects were studied in 12 patients with right coronary artery disease and AVB.
Results: Infusion therapy in patients with lower acute myocardial infarction, atrio-ventricular blockade and right ventricular failure corrects haemodynamic and dromotropic disturbances. Systolic arterial pressure (SAP) increased to 100,4 mmHg (9,9) after infusion of 400 mLin comparison with SAP after infusion of 200 mL (p = 0.003), Diastolic arterial pressure (DAP) increased to 58,7 mmHg (6,8) in comparison with DAP after infusion of 200 mL (p = 0.011), central venous pressure (CVP) decreased to 12.2 cmH2O (3,7) in comparison with CVP after infusion of 200 mL (p = 0.003). Mode of AVB degree indicator changed t 0O (0;0) (p = 0.028).
Conclusions: Infusion volume therapy should be used for correction of right ventricular failure and disturbances of atrio-ventricular conductivity in case of right ventricular failure absence.

Background: With the growing number of high-risk pregnant women, echocardiography frequently reveals pericardial effusion (PE). However, the clinical implications of PE are unknown.
Method: We analyzed a cohort of 406 high-risk pregnant women who underwent echocardiography in the third trimester between November 2019 and December 2022.

Background: Left ventricular (LV) myocardial contraction patterns can be assessed using LV mechanical dispersion (LVMD), a parameter closely associated with electrical activation patterns. Despite its potential clinical significance, limited research has been conducted on LVMD following myocardial infarction (MI). This study aims to evaluate the predictive value of cardiac magnetic resonance (CMR)-derived LVMD for adverse clinical outcomes and to explore its correlation with myocardial scar heterogeneity.

Background: Diastolic wall strain (DWS), also referred to as right ventricular (RV) dysfunction, is a significant predictor of pulmonary embolism (PE) and heart failure (HF). Rooted in linear elastic theory, DWS reflects decreased wall thinning during diastole, indicating reduced left ventricular (LV) compliance and increased diastolic stiffness. Elevated diastolic stiffness is associated with worse outcomes, particularly in PE and HF with preserved ejection fraction (HFpEF).

Introduction/objective: Atrial fibrillation (AF) could present with slow ventricular-response; bradycardia could facilitate the emergence of AF. The conviction that one "does not succumb" from bradycardia as an escape rhythm will emerge unless one sustains a fatal injury following syncope is in stark difference with ventricular tachyarrhythmia (VA), which may promptly cause cardiac arrest. However, this is not always the case, as a life-threatening situation may emerge during the bradycardic episode, i.

There are differing opinions in the literature regarding the cardiovascular safety of long-term methylphenidate use. Studies suggest that the drug may increase the risk of hypertension, myocardial infarction, ventricular arrhythmia, sudden cardiac death, cardiomyopathy, heart failure (HF), pulmonary hypertension, and stroke.
