Parvovirus B19 infection mimicking acute myocardial infarction.

abstract：BACKGROUND:Recent data highlight a vital link between well-performed cardiopulmonary resuscitation (CPR) and survival after cardiac arrest; however, the quality of CPR as actually performed by trained healthcare providers is largely unknown. We sought to measure in-hospital chest compression rates and to determine comp...
