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

open access: yesACS 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 ...

Pacemaker-accumulator model of time perception/scaler expectancy theory (SET).

open access: yes, 2022
Theory includes three main stages: the clock, memory, and decision-making. Emotion may affect arousal via the pacemaker, attention via the switch/gate, and/or bias the decision (for review see: [5].

Management of pacemaker patients after myocardial infarction

open access: yesМедицинский совет, 2021
Myocardial infarction (MI) is the leading cause of death and disability in the population. Effective restoration of coronary blood flow in the infarction-dependent artery during percutaneous coronary intervention contributes to the regression of ...

A Pacemaker that was Avoided [PDF]

open access: yesCureus, 2018
Thyroxine is an essential hormone in the human body and exerts many effects on the cardiovascular system. The low metabolic state in hypothyroidism causes bradycardia and reduced cardiac contractility leading to reduced cardiac output. Severe bradycardia and atrioventricular (AV) blocks secondary to hypothyroidism have also been reported.

A self-powered intracardiac pacemaker in swine model

open access: yesNature Communications
Harvesting biomechanical energy from cardiac motion is an attractive power source for implantable bioelectronic devices. Here, we report a battery-free, transcatheter, self-powered intracardiac pacemaker based on the coupled effect of ...

A case of dual atrioventricular nodal nonreentrant tachycardia: An unusual cause of tachycardia-induced cardiomyopathy

open access: yesJournal of Arrhythmia, 2015
We report on a 45-year-old female who developed cardiomyopathy due to incessant dual atrioventricular nodal nonreentrant tachycardia. Her condition was completely resolved by performing radiofrequency ablation of the slow pathway.

Pacemaker implantation following tricuspid valve annuloplastyCentral MessagePerspective

open access: yesJTCVS Open, 2023
Objective: Tricuspid annuloplasty is associated with increased risk of atrioventricular block and subsequent implantation of a permanent pacemaker. However, the exact incidence of permanent pacemaker, associated risk factors, and outcomes in this frame ...

The relationship of myocardial collagen metabolism and reverse remodeling after cardiac resynchronization therapy [PDF]

open access: yesJournal of Medical Biochemistry, 2016
Background: In the majority of patients with a wide QRS complex and heart failure resistant to optimal medical therapy, cardiac resynchronization therapy (CRT) leads to reverse ventricular remodeling and possibly to changes in cardiac collagen synthesis ...
