Bin right atrium systole starts: T, systole ends: U, in right ventricle systole starts: V, systole ends: Y
Cin right atrium systole starts: U, systole ends: V, in right ventricle systole starts: W, systole ends: X
Din right atrium systole starts: V, systole ends: W, in right ventricle systole starts: W, systole ends: Y
