Evaluation of the QA interval as an index of cardiac contractility in anaesthetised dogs: responses to changes in cardiac loading and heart rate.

abstract：:Infarct size can be limited by reducing the determinants of infarct size or increasing collateral blood flow by treatment initiated before the ischaemic event. Reperfusion is the definitive treatment for permanently reducing infarct size and restoring some degree of contractile function to the affected myocardium. Inn...
