Analysis of unipolar electrograms in rabbit heart demonstrated the key role of ventricular apicobasal dispersion in arrhythmogenicity.

Guérard N1, Jordaan P, Dumotier B.
Cardiovascular toxicology.Cardiovasc Toxicol.2014 Dec;14(4):316-28. doi: 10.1007/s12012-014-9254-2.
Reduced repolarization reserve and increased transmural dispersion of repolarization (TDR) are known risk factors for Torsade de Pointes development, but less is known about the role of apex-to-base (apicobasal) repolarization in arrhythmogenesis. Three needles were inserted in rabbit left ventricle

Raghuram A1, Clay R1, Kumbam A1, Tereshchenko LG1, Khan A1.
Journal of clinical sleep medicine : JCSM : official publication of the American Academy of Sleep Medicine.J Clin Sleep Med.2014 Oct 15;10(10):1155-60. doi: 10.5664/jcsm.4126.
INTRODUCTION: Obstructive sleep apnea (OSA) is an independent risk factor for sudden cardiac death. The aim of this review was to study the relationship between OSA and ventricular arrhythmias.METHODS: PubMed, Medline, and Cochrane databases were searched with MESH headings to find studies linking O

Paradoxical effects of KB-R7943 on arrhythmogenicity in a chronic myocardial infarction rabbit model.

Chang PC1, Wo HT1, Lee HL2, Wen MS1, Chou CC3.
Journal of cardiology.J Cardiol.2014 Sep 15. pii: S0914-5087(14)00246-9. doi: 10.1016/j.jjcc.2014.08.002. [Epub ahead of print]
BACKGROUND: Na+/Ca2+ exchanger blockade has been reported to be anti-arrhythmic in different models. The effects of KB-R7943, a Na+/Ca2+ exchanger blocker, on arrhythmogenesis in hearts with chronic myocardial infarction (MI) remain unclear.METHODS: Dual voltage and intracellular Ca2+ (Cai) optical
