CREATE TABLE table_77735 ("ATHLETE" TEXT, "FINAL" TEXT, "LANE" FLOAT, "SEMI" FLOAT, "QUART" FLOAT, "HEAT" FLOAT)

When a lane of 4 has a QUART greater than 44.62, what is the lowest HEAT?
SELECT MIN("HEAT") FROM table_77735 WHERE "LANE" = '4' AND "QUART" > '44.62'
SELECT MIN("HEAT") FROM "table_77735" WHERE "LANE" = '4' AND "QUART" > '44.62'
