Heart rhythm. 2018 Dec;().
The relationships between hemodynamic consequences of premature ventricular contractions (PVCs) and development of premature ventricular contraction-induced cardiomyopathy (PVC-CM) have not been investigated. The purpose of this study was to correlate concealed mechanical bradycardia and/or postextr

Influence of Amiodarone and Dronedarone on the Force-Interval Dependence of Rat Myocardium.

Kondratieva DS, Afanasiev SA, Popov SV.
BioMed research international. 2018 ;2018()4737489.
The antiarrhythmic effect of amiodarone and its analogue dronedarone is caused by their direct actions on several cardiomyocyte sarcolemmal ion currents. However, whether their effects are related to intracellular calcium levels is not exactly known. Ca cycling refers to the release and reuptake of
