An unusual ‘bow tie’ image in pacemaker implantation

Indian Pacing and Electrophysiology Journal, 2022
Upper venous system anatomic variations may cause difficulties during cardiac pacemaker implantation. Persistent left superior vena cava (PLSVC) and absent right superior vena cava could be an arrhythmogenic source of atrial arrhythmias and cardiac ...

Premature MicroRNA-1 Expression Causes Hypoplasia of the Cardiac Ventricular Conduction System. [PDF]

, 2019
Mammalian cardiac Purkinje fibers (PFs) are specified from ventricular trabecular myocardium during mid-gestation and undergo limited proliferation before assuming their final form.

Prolonged PR interval, first-degree heart block and adverse cardiovascular outcomes: a systematic review and meta-analysis [PDF]

, 2016
Objective: First-degree atrioventricular block is frequently encountered in clinical practice and is generally considered a benign process. However, there is emerging evidence that prolonged PR interval may be associated with adverse outcomes. This study

Left bundle branch pacing: An evolving site for physiological pacing

Journal of Arrhythmia, 2021
For patients with symptomatic bradyarrhythmia, cardiac pacing is the only appropriate treatment option. Electrical and mechanical dyssynchrony caused by traditional right ventricular apical pacing leads to left ventricular dysfunction and atrial ...

Cardiac conduction system- A detailed study in 46 cases of sudden death

Journal of Pathology of Nepal, 2015
Background: Atherosclerotic coronary artery disease is the modern pandemic and is said to be responsible for a major chunk of sudden cardiac deaths. However, in few cases; especially among the young, conduction system abnormalities were found to be the ...

Autopsy for Medical Diagnostics: Finding the Cause of Sudden Unexpected Death through Investigation of the Cardiac Conduction System by Serial Sections

Diagnostics, 2023
Sudden unexpected death (SUD) is a fatal event that occurs in an apparently healthy subject in a way that such an abrupt outcome could have not been predicted.

Rapidly Progressive Cardiac Manifestation of Behçet's Disease Involving Conduction System and Aortic Valve [PDF]

Journal of Cardiovascular Ultrasound, 2011
Cardiac conduction system impairment is a rare clinical manifestation of Behçet's disease. We report a patient who showed 1st degree atrioventricular block at first presentation, and showed aggravated finding of 3rd degree atrioventricular block on five months later.

Genetic and physiologic dissection of the vertebrate cardiac conduction system.

PLoS Biology, 2008
Vertebrate hearts depend on highly specialized cardiomyocytes that form the cardiac conduction system (CCS) to coordinate chamber contraction and drive blood efficiently and unidirectionally throughout the organism.
