Summation Gallop at 120 beats per minute #31

Auscultation in Primary Care

At a heart rate of 120 beats per minute, the diastolic period is shortened. This causes the third and fourth sound to be superimposed, creating a single loud sound.

The anatomy tab shows an enlarged left ventricle with decreased left ventricular contractility and a minimally enlarged left atrium.

After reviewing the sound, use the waveform and anatomy tabs for more information about this sound.
