Post-cardiac injury syndrome following transvenous pacing: Case report
Revista Portuguesa de Cardiologia, 2014 Post-cardiac injury syndrome (PCIS) is an inflammatory process involving the pericardium secondary to cardiac injury. It can develop after cardiac trauma, cardiac surgery, myocardial infarction, and, rarely, after certain intravascular procedures.

Slow ventricular tachycardia presenting with acute liver failure
SAGE Open Medical Case Reports, 2017 Objectives: Cardiac hepatopathy is an important differential diagnosis of acute liver failure. Slow ventricular tachycardia (slow VT) is a ventricular tachycardia (VT), in which heart rate is below the typical frequency of VT.

Low‐field MRI: Clinical promise and challenges
Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 25-44, January 2023., 2023 Modern MRI scanners have trended toward higher field strengths to maximize signal and resolution while minimizing scan time. However, high‐field devices remain expensive to install and operate, making them scarce outside of high‐income countries and major population centers.

Integrative Approach - New Level Knowledge of Functions: Opportunities and Prospects [PDF]
, 2012 In this article, the example of the mechanisms of heart rhythmogenesis in the intact organism is used to demonstrate the new capabilities provided by an integrative approach. It is shown that the rhythm is formed in the brain, transmitted to the heart in

Journal of Neuroscience Research, Volume 101, Issue 2, Page 263-277, February 2023., 2023 Substantia nigra (SN) hyperechogenicity, viewed with transcranial ultrasound, is a risk marker for Parkinson's disease. SN hyperechogenicity in healthy older adults is associated with changes in the excitability of specific motor cortical circuitry. These changes are unrelated to glutamate levels in the pre‐supplementary motor area (pre‐SMA).

Early performance of a miniaturized leadless cardiac pacemaker: the Micra Transcatheter Pacing Study
European Heart Journal, 2015 Aims Permanent cardiac pacing is the only effective treatment for symptomatic bradycardia, but complications associated with conventional transvenous pacing systems are commonly related to the pacing lead and pocket.
