Recovery of complete left bundle branch block in dilated cardiomyopathy after optimal heart failure treatment: a case report [PDF]

Journal of Medicine and Life Science
Complete left bundle branch block (CLBBB) is a significant cardiac conduction abnormality often associated with dilated cardiomyopathy (DCM). This case report highlights the improvement in CLBBB and symptom relief through reverse cardiac remodeling in a ...

Feasibility of selective cardiac ventricular electroporation.

PLoS ONE, 2020
IntroductionThe application of brief high voltage electrical pulses to tissue can lead to an irreversible or reversible electroporation effect in a cell-specific manner. In the management of ventricular arrhythmias, the ability to target different tissue

Segregation of Central Ventricular Conduction System Lineages in Early SMA+ Cardiomyocytes Occurs Prior to Heart Tube Formation

Journal of Cardiovascular Development and Disease, 2016
The cardiac conduction system (CCS) transmits electrical activity from the atria to the ventricles to coordinate heartbeats. Atrioventricular conduction diseases are often associated with defects in the central ventricular conduction system comprising ...

Renal denervation reverses ventricular structural and functional remodeling in failing rabbit hearts

Scientific Reports, 2023
Renal denervation (RDN) suppresses the activity of the renin–angiotensin–aldosterone system and inflammatory cytokines, leading to the prevention of cardiac remodeling.

Conduction System Pacing for Cardiac Resynchronization Therapy

Journal of Cardiovascular Development and Disease, 2023
Cardiac resynchronization therapy (CRT) via biventricular pacing (BiVP-CRT) is considered a mainstay treatment for symptomatic heart failure patients with reduced ejection fraction and wide QRS. However, up to one-third of patients receiving BiVP-CRT are

Phenotypically silent Cre recombination within the postnatal ventricular conduction system. [PDF]

PLoS ONE, 2017
The cardiac conduction system (CCS) is composed of specialized cardiomyocytes that initiate and maintain cardiac rhythm. Any perturbation to the normal sequence of electrical events within the heart can result in cardiac arrhythmias.

Aspects of myocardial heterogeneity in assessment its remodeling

RUDN Journal of Medicine, 2022
The influence of sports activity on the cardiovascular system is accompanied by physiological adaptation of the organism. Intense physical activity, far exceeding the body’s capabilities, can lead to structural changes or remodeling of the athlete’s ...

ECG Paper Digitization and R Peaks Detection Using FFT

Applied Computational Intelligence and Soft Computing, 2022
An electrocardiogram (ECG) uses electrodes to monitor the heart rhythm and identify minute electrical changes that occur with each beat. It is employed to investigate particular varieties of aberrant heart activity, such as arrhythmias and conduction ...

Simultaneous assessment of mechanical and electrical function in Langendorff-perfused ex-vivo mouse hearts

Frontiers in Cardiovascular Medicine, 2023
BackgroundThe Langendorff-perfused ex-vivo isolated heart model has been extensively used to study cardiac function for many years. However, electrical and mechanical function are often studied separately—despite growing proof of a complex electro ...

Conduction defects and arrhythmias in mdx mice are not associated with a degeneration of the cardiac Purkinje network

Frontiers in Physiology
Duchenne muscular dystrophy (DMD) is a severe X-chromosomal disease characterised by progressive muscle weakness and degeneration. Cardiac involvement is inevitable in DMD patients and ventricular arrhythmias are a high-risk factor for mortality in these
