THE RISK OF PREMATURE VENTRICULAR CONTRACTIONS DEPENDING ON PARAMETERS OF THE LEFT VENTRICULAR SYSTOLIC FUNCTION AMONG PATIENTS WITH ACUTE MYOCARDIAL INFARCTION

Сучасні медичні технології, 2019
Despite the preventive measures taken to reduce the incidence of coronary heart disease, cardiovascular diseases remain the leading cause of death. In patients with acute myocardial infarction ventricular arrhythmias can be an important prognostic factor.

Frequent Ventricular Premature Complex-Induced Decompensated Heart Failure

, 2015
Asymptomatic premature ventricular beats are most common presentation form of arrhyth-mia observed in patients with or without structural heart disease. In long term, frequent pre-mature ventricular beats can lead left ventricule failure in structurally ...

Cardiac function in children with premature ventricular contractions: the effect of omega-3 polyunsaturated fatty acid supplementation

, 2018
BackgroundPremature ventricular contractions are accepted as benign in structurally normal hearts. However, reversible cardiomyopathy can sometimes develop.

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

Advanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

Refractory Premature Ventricular Complex Triggered Ventricular Fibrillation Responsive to Cardiac Sympathetic Denervation

Annals of Internal Medicine: Clinical Cases, 2022
A healthy 34-year-old woman sustained refractory idiopathic ventricular fibrillation (IVF) secondary to premature ventricular contractions (PVCs). Ischemic, structural, and genetic evaluations did not identify an attributable pathology.

Microfluidic Droplet Plate Preserving Single Human Induced Pluripotent Stem Cell‐Derived Cardiomyocytes Morphology and Function

Advanced Materials Technologies, EarlyView.
We introduce a novel method combining microfluidics, optogenetics, and human induced pluripotent stem cell (iPSC) technology to encapsulate single iPSC‐derived cardiomyocytes (iPSC‐CMs) in an optimal environment for functional characterization. This method enables direct genotype‐phenotype correlation for genetic studies and high‐throughput screening ...

MODULATION OF THE SEVERITY OF REPERFUSION-INDUCED ARRHYTHMIAS BY DIGOXIN IN THE ISOLATED RAT HEART

Zagazig Journal of Pharmaceutical Sciences, 1993
In the present investigation, the effects of different concentrations of digoxin (5x10-8 -5 x 10-6 M) on the number of premature ventricular contractions (PVCS), incidence, onset and duration of ventricular tachycardia (VT) and fibrillation (VF) have ...

A Dual‐Modal Wearable PPG Smartwatch with AI‐Enhanced Correction for High‐Accuracy and Continuous AF Burden Assessment

Advanced Science, EarlyView.
ABSTRACT Atrial fibrillation (AF) increases the risk of stroke and heart failure, yet accurate quantification of AF burden in daily life remains difficult. Although smartwatch photoplethysmography (PPG) supports continuous monitoring, complex rhythms and signal noise can impair burden estimation.
