Summation Gallop at 120BPM

Virtual Auscultation

The patient's position should be supine.

Lesson

With high heart rates, in this case 120 BPM, the diastolic interval is shortened. Accordingly, S3 and S4 sounds begin to merge, producing a single loud heart sound.

The cardiac animation video presents an enlarged left ventricle with decreased left ventricular contractility and a minimally enlarged left atrium.
