Doctors Test Digital 'Twins' to Treat Irregular Heartbeats

Scientists have created precise virtual replicas of patients' diseased hearts, allowing doctors to test treatments on these digital 'twins' before operating on the real thing. One of the first clinical trials of this approach suggests it could improve care for people with dangerous irregular heartbeats.

Why it matters

This innovative use of digital modeling represents a major advancement in personalized medicine, as it allows doctors to safely experiment and optimize treatment plans for each individual patient's unique heart condition before performing any actual procedures.

The details

The custom heart models are created using data from medical scans and other tests. Doctors can then use these digital replicas to experiment with different treatment approaches, such as blocking irregular heartbeats, without putting the real patient at risk. In one recent trial, this technique helped guide doctors in successfully treating a patient's ventricular tachycardia, a potentially life-threatening irregular heartbeat.

• The first clinical trials of these digital heart models were conducted in 2026.

What’s next

Doctors plan to continue expanding the use of these digital heart models to guide treatment for a wider range of cardiac conditions.
