Air travel could raise the risk for experiencing heartbeat irregularities among older individuals with a history of heart disease.

Researchers assessed of a group of 40 people in an environment which simulated flight conditions. The average age of the participants was 64. One-third of them had been previously diagnosed with heart disease.

The study showed that the absolute risk for experiencing extra heartbeats did not appear to be greater while passengers were in flight conditions.

However, in instances where cardiac irregularity had occurred, the researchers found those with a prior history of heart disease had a higher rate of extra heartbeats while airborne.
