INTERNAL CARDIAC PACEMAKERS [PDF]

American Journal of Roentgenology, 1967
There are two main pacemaker systems used in controlling the cardiac rate in Severe heart-block patients: (1) asynchronous, and (2) synchronous or P-wave actuated.These pacemakers transmit current to the electrodes by direct wire or electromagnetic communications.The main techniques of applying the myocardial electrodes to the ventricles are: (1 ...

SHOX2 Overexpression Favors Differentiation of Embryonic Stem Cells into Cardiac Pacemaker Cells, Improving Biological Pacing Ability

Stem Cell Reports, 2015
Summary: When pluripotency factors are removed, embryonic stem cells (ESCs) undergo spontaneous differentiation, which, among other lineages, also gives rise to cardiac sublineages, including chamber cardiomyocytes and pacemaker cells. Such heterogeneity

Infection and migration incidence of cardiac implantable electrical devices in Japan: Web‐based survey results

Journal of Arrhythmia, 2020
Web‐based survey was conducted for experiences of cardiac implantable electrical device (CIED) infection and migration in Japan. A total of 155 cardiologists’ answer was collected in January, 2018.

An unusual case of disseminated intravascular coagulation [PDF]

, 2017
The use of cardiac pacemakers is increasing worldwide. Infective endocarditis from a pacemaker lead is a rare, but one of the most severe complications of pacemaker insertion.

Pacemaker Dependency after Cardiac Surgery: A Systematic Review of Current Evidence.

PLoS ONE, 2015
BackgroundSevere postoperative conduction disturbances requiring permanent pacemaker implantation frequently occur following cardiac surgery. Little is known about the long-term pacing requirements and risk factors for pacemaker dependency in this ...

Cardiac magnetic resonance in a patient with MRI-conditional pacemaker

Revista Portuguesa de Cardiologia, 2013
An implanted pacemaker is generally considered a contraindication for magnetic resonance imaging (MRI). The increasing number of indications for MRI and the rising prevalence of implanted cardiac pacemakers have prompted the recent development of MRI ...

Impact of functional studies on exome sequence variant interpretation in early-onset cardiac conduction system diseases [PDF]

, 2020
Aims The genetic cause of cardiac conduction system disease (CCSD) has not been fully elucidated. Whole-exome sequencing (WES) can detect various genetic variants; however, the identification of pathogenic variants remains a challenge.

Potential effects of intrinsic heart pacemaker cell mechanisms on dysrhythmic cardiac action potential firing

Frontiers in Physiology, 2015
The heart’s regular electrical activity is initiated by specialized cardiac pacemaker cells residing in the sinoatrial node. The rate and rhythm of spontaneous action potential firing of sinoatrial node cells are regulated by stochastic mechanisms that ...

Post-cardiac injury syndrome occurred two months after permanent dual-chamber pacemaker implantation

BMC Cardiovascular Disorders, 2023
Background Post cardiac injury syndrome (PCIS) is characterized by the development of pericarditis with or without pericardial effusion due to a recent cardiac injury. The relatively low incidence makes diagnosis of PCIS after implantation of a pacemaker

Subacute Right Ventricle Perforation by Pacemaker Lead Presenting with Left Hemothorax and Shock

Case Reports in Cardiology, 2015
Cardiac perforation by pacemaker is a rare but potentially fatal complication. Acute perforations occurring within twenty-four hours of insertion of pacemaker can lead to hemopericardium, cardiac tamponade, and death.
