In addition to these normalsounds,a variety of other sounds may be present including heartmurmurs,adventitious sounds, and gallop rhythms S3 and S4.

Heart murmurs are generated by turbulent flow of blood, whichmayoccur inside or outside the heart. Murmurs may bephysiological(benign) or pathological (abnormal). Abnormal murmurscan be causedby stenosis restricting the opening of a heart valve,resulting inturbulence as blood flows through it. Abnormal murmursmay alsooccur with valvular insufficiency (regurgitation), whichallowsbackflow of blood when the incompetent valve closes withonlypartial effectiveness.
