Development of the cardiac pacemaker [PDF]

Cellular and Molecular Life Sciences, 2016
The sinoatrial node (SAN) is the dominant pacemaker of the heart. Abnormalities in SAN formation and function can cause sinus arrhythmia, including sick sinus syndrome and sudden death. A better understanding of genes and signaling pathways that regulate SAN development and function is essential to develop more effective treatment to sinus arrhythmia ...

Long-term effect of cardiac pacing on sleep-disordered breathing in patients with conventional indications for a permanent pacemaker

Journal of Arrhythmia, 2014
Background: The effect of cardiac pacing on sleep-disordered breathing is controversial. We investigated the long-term effect of cardiac pacing on sleep disordered breathing in patients with conventional indications for permanent pacemakers Methods ...

Testing of Common Electromagnetic Environments for Risk of Interference with Cardiac Pacemaker Function

Safety and Health at Work, 2013
Background: Cardiac pacemakers are known to be susceptible to strong electromagnetic fields (EMFs). This in vivo study investigated occurrence of electromagnetic interference with pacemakers caused by common environmental sources of EMFs. Methods: Eleven

Cardiomyopathy Induced by Artificial Heart Stimulation

Journal of Cardiac Arrhythmias, 2020
With the advent of cardiac pacemakers more than 60 years ago, the era of artificial cardiac pacing began, which changed the natural history of symptomatic bradycardias, significantly increasing the survival especially of patients with complete ...

Novel Insights into the Sinoatrial Node in Single-Cell RNA Sequencing: From Developmental Biology to Physiological Function

Journal of Cardiovascular Development and Disease, 2022
Normal cardiac automaticity is dependent on the pacemaker cells of the sinoatrial node (SAN). Insufficient cardiac pacemaking leads to the development of sick sinus syndrome (SSS). Since currently available pharmaceutical drugs and implantable pacemakers

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 ...
