A heart murmur is defined as an unusual sound heard during a heartbeat, often described as a whooshing or swishing sound in addition to the normal "lub-dub" sounds of the heart. This murmur can indicate the presence of turbulent blood flow, which is frequently associated with issues relating to heart valves. For instance, a murmur may suggest that a valve is not opening or closing correctly, leading to backflow of blood or restricted blood flow. Therefore, a heart murmur is often evaluated as a potential signal of underlying cardiovascular conditions, particularly related to valvular heart disease.

Normal heart function and a routine heart rhythm would not typically present with any abnormal sounds; thus, they do not align with the presence of a murmur. High blood pressure might contribute to cardiovascular issues, but it is not directly indicated by the sound of a murmur itself. Instead, it is the specific nature of the murmur that points towards potential valve-related problems.
