The role of cardiac pacing therapy in the management of carotid sinus syndrome [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2015
Introduction. Carotid sinus syndrome is characterized by a hypersensitive carotid sinus and syncope. Although we have clear guidelines for the diagnosis and treatment of carotid sinus syndrome, the efficacy of pacing therapy with this indication

Is pacemaker therapy the right key to patients with vasovagal syncope? [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2016
Introduction. Vasovagal syncope is the most common type of reflex syncope. Efficacy of cardiac pacing in this indication has not been the subject of many studies and pacemaker therapy in patients with vasovagal syncope is still controversial ...

Endogenous driving and synchronization in cardiac and uterine virtual tissues: bifurcations and local coupling [PDF]

, 2006
Cardiac and uterine muscle cells and tissue can be either autorhythmic or excitable. These behaviours exchange stability at bifurcations produced by changes in parameters, which if spatially localized can produce an ectopic pacemaking focus.

Symbiotic cardiac pacemaker

Nature Communications, 2019
Self-powered implantable medical electronic devices that harvest biomechanical energy from cardiac motion, respiratory movement and blood flow are part of a paradigm shift that is on the horizon. Here, we demonstrate a fully implanted symbiotic pacemaker

Canonical Wnt signaling promotes pacemaker cell specification of cardiac mesodermal cells derived from mouse and human embryonic stem cells

Stem Cells, 2020
Cardiac differentiation of embryonic stem cells (ESCs) can give rise to de novo chamber cardiomyocytes and nodal pacemaker cells. Compared with our understanding of direct differentiation toward atrial and ventricular myocytes, the mechanisms for nodal ...

Prototypical pacemaker neurons interact with the resident microbiota

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Here, we discover prototypical pacemaker neurons in the ancient cnidarian Hydra and provide evidence for a direct interaction of these neurons with the commensal microbiota.

Restricted feeding uncouples circadian oscillators in peripheral tissues from the central pacemaker in the suprachiasmatic nucleus.

Genes & Development, 2000
In mammals, circadian oscillators exist not only in the suprachiasmatic nucleus, which harbors the central pacemaker, but also in most peripheral tissues.

Direct Powering a Real Cardiac Pacemaker by Natural Energy of a Heartbeat.

ACS Nano, 2019
Implantable medical devices are widely used for monitoring and treatment of severe diseases. In particular, an implantable cardiac pacemaker is the most effective therapeutic device for treating bradyrhythmia, however its surgical replacement is ...
