Certified Cardiac Rehabilitation Professional (CCRP) Practice Test

The primary characteristic of heart murmurs is the presence of odd or additional heart sounds that are typically caused by turbulent blood flow within the heart or through the blood vessels. These sounds can vary in intensity and quality, such as being described as blowing, whooshing, or rumbling, and are often heard during specific phases of the heartbeat.

Murmurs can indicate various cardiac conditions, including structural heart defects, valve abnormalities, or increased blood flow through the heart. While irregular blood flow contributes to the formation of murmurs, the defining feature is the resultant sound heard upon auscultation, distinguishing them from other heart-related phenomena. Understanding the characteristics of heart murmurs is crucial for nursing and rehabilitation professionals, as it helps in diagnosing underlying cardiovascular issues that may require further evaluation or intervention.
