Quizplus · Accepted Answer

Factors that restrict ventricular expAnswerion during diastole include 
(1) an already overstretched, distended ventricle; 
(2) pericardial tamponade; 
(3) myocardial infarction; and 
(4) the increased pressure surrounding the heart during positive pressure mechanical ventilation, especially in the presence of high levels of positive end-expiratory pressure (PEEP).
