Lubb - Sharp closure of AV valves at the beginning of ventricular systole
Lubb (first sound, systolic sound) is the first heart sound which is low pitched, not very loud, of long duration (about 0.15 seconds) and is produced partly due to closure of atria-ventricular valves (tricuspid and bicuspid) and partly by the contraction of the muscles in the ventricles
