Gallop rhythm
Gallop Rhythm
Gallop rhythm (pronunciation: /ˈɡæl.əp ˈrɪð.əm/) is a specific type of abnormal heart rhythm that is characterized by three or four sounds in each cardiac cycle, similar to the sound of a galloping horse.
Etymology
The term "gallop rhythm" is derived from the English word "gallop," which is used to describe the fast, bounding gait of a horse. This term was chosen due to the similarity between the sound of a galloping horse and the sound of the heart when this rhythm is present.
Types of Gallop Rhythm
There are two types of gallop rhythms: the S3 gallop and the S4 gallop.
The S3 gallop is a low-frequency sound that occurs in early diastole, immediately after the S2 sound. It is often associated with conditions that cause rapid ventricular filling, such as congestive heart failure.
The S4 gallop is a low-frequency sound that occurs in late diastole, just before the S1 sound. It is often associated with conditions that cause increased resistance to ventricular filling, such as hypertension or aortic stenosis.
