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 ...

CaMKII-dependent regulation of cardiac Na(+) homeostasis. [PDF]

, 2014
Na(+) homeostasis is a key regulator of cardiac excitation and contraction. The cardiac voltage-gated Na(+) channel, NaV1.5, critically controls cell excitability, and altered channel gating has been implicated in both inherited and acquired arrhythmias.

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 ...

Giant cell myocarditis masquerading as orbital myositis with a rapid, fulminant course necessitating mechanical support and heart transplantation. [PDF]

, 2017
Giant cell myocarditis (GCM), a rapidly progressive inflammation of the myocardium, is associated with fulminant heart failure, refractory ventricular arrhythmias, and conduction system abnormalities.

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

Novel Behavior of the 2019 Novel Coronavirus With Invasion of the Cardiac Conduction System in the Young

Cureus, 2020
We report the case of a 35-year-old man (an oil engineer) referred as a coronavirus disease-2019 (COVID-19) case with heart block and a four-day history of headache and fever.

Predictive factors of atrioventricular conduction disorders [PDF]

Romanian Medical Journal
Atrioventricular conduction disorders represent an alteration in the normal function of the heart’s electrical conduction system, a system that connects the atria and ventricles through the atrio-ventricular node and the His-Purkinje system. Consequently,

Sodium leak through K2P potassium channels and cardiac arrhythmia, an emerging theme. [PDF]

, 2017
In this issue of EMBO Molecular Medicine, Decher et al (2017) identify a point mutation in the K2P2 (TREK‐1) potassium (K+) channel that changes function in just those ways expected to predispose to right ventricular outflow tract (RVOT) ventricular
