The normal heartbeat is 60-72 per minute. The pumping of the blood from the heart to every part of the body through blood vessels causes the sound in it. A healthy adult normally has two heart sounds, commonly called as lub and dub (or dup). These sounds are caused by the systole and diastole; systole occurs when the hearts contracts and the blood is pumped out, whereas diastole occurs when the heart relaxes after contraction. Because of the contraction and relaxation of heart the intensity and the pitch of the sound differs. The first sound (S1) is of low frequency and occurs at the beginning of systole. This sound can be heard clearly using the stethoscope or at the diaphragm. It is caused due to the turbulence created during the closure of mitral and tricuspid valves. The second sound (S2) is comparatively short than the first sound in terms of intensity, frequency, quality and duration. S2 is caused by the closure of the aortic and pulmonic valves, making the end of systole. 2. An unusual sound heard between the heartbeats is known as the heart murmur. They generally produce whooshing or swishing noise. Sometimes the murmurs maybe harmless (innocent), but if they are occurring consistently or they accompany any other problems (abnormal) then they should be diagnosed. Innocent murmurs can be caused due to physical activity, pregnancy, general sickness such as fever, anaemia, hyperthyroidism or rapid stages of development (adolescence). Abnormal heart murmurs can be caused due to holes in the heart or presence of cardiac shunts, abnormalities in the heart valve, valve calcification and sometimes due to rheumatic fever. People with family history of heart defects and certain illness (lung diseases, hypertension etc.) are also at risk of developing heart murmurs. Solution The normal heartbeat is 60-72 per minute.
