Among the fatal vascular complications associated with autosomal dominant polycystic disease (ADPKD), ruptured intracerebral aneurysm and ruptured abdominal aortic aneurysm are widely known. However, there are few reports on the dissecting thoracic aortic aneurysm as a fatal complication of ADPKD. We report a case of a 58-year-old man with a history of ADPKD who presented to the emergency department with out-of-hospital cardiac arrest. ⋯ The surgical specimen of the aorta showed cystic medial necrosis. This rare case emphasizes the need to consider such a diagnosis in a patient with ADPKD who presents to the emergency department with sudden cardiac arrest. In addition, the histological finding indicates the aetiological role of a collagen defect in addition to chronic hypertension in the pathogenesis of aortic dissection in ADPKD patients.

Defibrillation may convert ventricular fibrillation (VF) only to reveal profound mechanical dysfunction. Survival following this dysfunction, known as pulseless electrical activity (PEA) and electromechanical dissociation (EMD), is uncommon. We sought to evaluate an electrical therapy for primary post shock PEA following short duration VF. ⋯ Electrical therapy increased the likelihood of ROSC in primary post defibrillation PEA three-fold (P < 0.01). Recovery occurred in the absence of thoracic compression, mechanical ventilation, or adjunctive drug therapy.

Comparative Study
Progress of the advanced life support courses in Europe and beyond.
The Advanced Life Support (ALS) course was designed initially to teach, and thereby enhance the practice and effectiveness of, resuscitation from cardiac arrest. The target candidates were doctors, nurses and paramedics, and particularly those working in areas likely to encounter such an emergency.

The Guidelines 2000 for CPR and ECC recommend for single lay-rescuers performing basic life support, "two quick breaths followed by 15 chest compressions", repeated until professional help arrives. It is uncertain that this can actually be accomplished by the majority of lay rescuers. We evaluated 53 first-year medical students after completing BLS CPR training to determine if they could deliver the goal of 80 compressions per minute when following this AHA BLS recommendation. ⋯ For single rescuer basic cardiopulmonary resuscitation, motivated BLS CPR-trained medical students take nearly as long as previously reported for middle-aged lay individuals to deliver these "two quick breaths". The "Guidelines 2000" recommendation for "two quick breaths" is an oxymoron, as it averages more than 13s. New recommendations for single-rescuer CPR should be considered that emphasize uninterrupted chest compressions.
