Heart arrhythmias and conduction disorders in patients with acromegaly: the role of cardiac magnetic resonance imaging

Терапевтический архив, 2020
Cardiovascular complications including arrhythmias and cardiac conduction disorders are one of the main reasons of high mortality rate in acromegaly, while they have not been well explored. Aim.To estimate arrhythmias frequency in acromegaly, identify

Proarrhythmia associated with antiarrhythmic drugs: a comprehensive disproportionality analysis of the FDA adverse event reporting system

Frontiers in Pharmacology, 2023
Objective: This study aimed to identify the different associations between antiarrhythmic drugs (AADs) and arrhythmias, and to determine whether pharmacokinetic drug interactions involving AADs increase the risk of AAD-related arrhythmias compared to ...

Pattern Formation in Non‐Equilibrium Architected Materials

Advanced Materials Technologies, EarlyView.
This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.

Case Report: A rare case of symptomatic bradycardia secondary to aripiprazole in a patient with bipolar disorder type I [version 1; peer review: 2 approved, 1 approved with reservations]

F1000Research, 2022
It is well known that typical antipsychotic drugs have been implicated as a cause of ventricular arrhythmias and cardiac arrest; studies have shown that conventional antipsychotics increase the risk of hospitalization for ventricular arrhythmias or ...

Regional differences in APD restitution can initiate wavebreak and re-entry in cardiac tissue: A computational study [PDF]

, 2005
Background Regional differences in action potential duration (APD) restitution in the heart favour arrhythmias, but the mechanism is not well understood.

Chemically Doped Conductive Polymers for Wearable Health Monitoring

Advanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.

Clinical presentations, diagnosis, and management of arrhythmias associated with cardiac tumors

Journal of Arrhythmia, 2018
Cardiac tumors are a rare cause of arrhythmias in clinical practice. They can cause a broad spectrum of arrhythmias, from low‐grade ectopics to incessant ventricular tachycardias, including sudden cardiac arrest. Both primary and secondary cardiac tumors
