Heartbeat secrets unlocked as cardiac rhythm gene role identified

Researchers have used the zebrafish (Danio rerio) to identify the role of a gene involved in cardiac rhythm, which could help explain the fundamentals of what it takes to make a human heartbeat.

The University of Melbourne study also found that mutation of the gene, Tmem161b, causes potentially fatal cardiac arrhythmia. 2.5 per cent of Australians are living with cardiac arrhythmia ( END
