Morphology

asystole = systole (semi-transparent) = a + systole

Formally 'a-' (without) + 'systole' yields 'absence of systole', but both elements are medical/technical and may not be known to general learners.

Etymology

Asystole comes from the Greek parts a- meaning 'without' and systole meaning 'a squeeze' or 'contraction', like in 'systolic' blood pressure. So asystole means the heart is 'without a squeeze' and has stopped beating.
