2. If the heart rate is also very fast ( tachycardia ), it can become difficult to distinguish between S 3 and S 4 thus producing a single sound called a "'summation gallop " '.
3. It can also contain both of these sounds forming a "'quadruple gallop "', and in situations of very fast heart rate can produce a "'summation gallop "'where S 3 and S 4 occur so close as to be indistinguishable.
