Pulsebeat

The problem

One in six heart-surgery patients is readmitted within a month, usually for a rhythm problem nobody saw developing at home.

The solution

Pulsebeat is a patch worn for 30 days that streams heart rhythm to the ward, alerting nurses to trouble days before it becomes an emergency.

Who it's for

Cardiac units in public and private hospitals.
