Understanding Decreased Stroke Volume: Causes, Impacts, and Management Strategies Stroke volume—the amount of blood ejected from the left ventricle with each heartbeat—plays a critical role in maintaining adequate cardiac output and systemic perfusion. When stroke volume decreases, the heart struggles to meet the body’s demands, potentially leading to fatigue, dizziness, and more severe cardiovascular complications. In this SEO-optimized article, we’ll explore what decreased stroke volume means, its common causes, symptoms, diagnostic approaches, and treatment options. ### What Is Stroke Volume and Why Does It Matter? Stroke volume (SV) is calculated as the difference between end-diastolic volume (EDV) and end-diastolic volume minus the volume of blood ejected (end-systolic volume, ESV):
SV = EDV – ESV
