OBJECTIVES This study examined the effect of radiofrequency ablation (RFA) on left atrial (LA) and left atrial appendage (LAA) function in humans with chronic atrial flutter (AFL). BACKGROUND Atrial stunning and the development of spontaneous echocardiographic contrast (SEC) is a consequence of electrical cardioversion of AFL to sinus rhythm. This phenomenon has been termed "stunning" and is ...

Billions of poultry are slaughtered globally each year to provide protein for a rapidly expanding human population. The large number birds produced in conventional systems presents animal welfare issues during production, transport, and at the time slaughter. While we recognise significance rearing this paper highlights impacts manual handling, inversion shackling, use inappropriate electrical ...

Introduction Conscious pigs underwent a sequence of 10 2-min coronary occlusions, each separated by 2 min of reperfusion, for three consecutive days (days 1, 2, and 3 of stage I). The recovery of systolic wall thickening (WTh) after the 10th reperfusion was markedly improved on days 2 and 3 compared with day 1, indicating that the myocardium had become preconditioned against "stunning." 10 d af...

by Activation of Sarcolemmal but not Mitochondrial ATP-Sensitive Potassium Channels in Mice To the Editor: Recently, Suzuki et al1 reported that attenuation of myocardial stunning by diazoxide in mice was mediated through activation of sarcolemmal rather than mitochondrial K ATP channels. Although the authors used an elegant approach by combining both pharmacological tools (utilizing the mitoch...
