His brother, Cleveland Browne, disclosed that Dalton is expected to undergo quadruple heart bypass surgery this weekend at the University Hospital of the West Indies in Kingston.
He said the Browne family are asking for blood donations to assist with the surgery.
Dalton Browne, 64, is the second of five brothers all of whom are musicians. Glen (bass), Noel (keyboards), Cleveland (keyboards) and guitarist Danny are his siblings.
Dalton, a member of the 12 Tribes of Israel, is the longtime musical director for Freddie McGregor's band. He has played on the singer's biggest hit songs including "Big Ship", "Push Come to Shove" and "Prophecy".
Glen has toured with Jimmy Cliff, Tarrus Riley and Ziggy Marley and The Melody Makers. Cleveland is best known as half of Steely and Clevie, while Danny operated Main Street Records before becoming a Christian and concentrating on gospel music.
The brothers were once known as The Browne Bunch which formed during the early 1970s.
