Symbiotic cardiac pacemaker [PDF]
Nature Communications, 2019 Implantable medical electronic devices are limited by battery lifetime and inflexibility, but self-powered devices can harvest biomechanical energy. Here the authors demonstrate cardiac pacing and correction of sinus arrhythmia with a symbiotic cardiac ...

On the Evolution of the Cardiac Pacemaker [PDF]
Journal of Cardiovascular Development and Disease, 2017 The rhythmic contraction of the heart is initiated and controlled by an intrinsic pacemaker system. Cardiac contractions commence at very early embryonic stages and coordination remains crucial for survival.

Self-rechargeable cardiac pacemaker system with triboelectric nanogenerators [PDF]
Nat Commun, 2021 Self-powered implantable devices have the potential to extend device operation time inside the body and reduce the necessity for high-risk repeated surgery. Without the technological innovation of in vivo energy harvesters driven by biomechanical energy,

A compact and miniaturized implantable antenna for ISM band in wireless cardiac pacemaker system [PDF]
Sci Rep, 2022 A tiny and compact implantable antenna for wireless cardiac pacemaker systems is designed. The antenna works in the Industrial Scientific Medical (ISM) frequency band (2.4–2.48 GHz).

Design and implementation of compact dual-band conformal antenna for leadless cardiac pacemaker system [PDF]
Sci Rep, 2022 The leadless cardiac pacemaker is a pioneering device for heart patients. Its rising success requires the design of compact implantable antennas. In this paper, we describe a circularly polarized Hilbert curve inspired loop antenna.

Improved Generation of Human Induced Pluripotent Stem Cell-Derived Cardiac Pacemaker Cells Using Novel Differentiation Protocols [PDF]
Int J Mol Sci, 2022 Current protocols for the differentiation of human-induced pluripotent stem cells (hiPSC) into cardiomyocytes only generate a small amount of cardiac pacemaker cells. In previous work, we reported the generation of high amounts of cardiac pacemaker cells

Engineered Cardiac Pacemaker Nodes Created by TBX18 Gene Transfer Overcome Source–Sink Mismatch
Advanced Science, 2019 Every heartbeat originates from a tiny tissue in the heart called the sinoatrial node (SAN). The SAN harbors only ≈10 000 cardiac pacemaker cells, initiating an electrical impulse that captures the entire heart, consisting of billions of cardiomyocytes ...

Something that Touches your Heart: an Unusual Case of Abdominal Clonic Movements. [PDF]
Tremor and Other Hyperkinetic Movements, 2019 Background: Rarely, cardiac pacemaker implant can lead to the development of involuntary hyperkinetic movement disorders localized to the abdominal wall or the diaphragm.

Cardiac Pacemaker Activity and Aging. [PDF]
Annu Rev Physiol, 2019 A progressive decline in maximum heart rate (mHR) is a fundamental aspect of aging in humans and other mammals. This decrease in mHR is independent of gender, fitness, and lifestyle, affecting in equal measure women and men, athletes and couch potatoes ...

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 ...
