A study from England discovered that carrying out an electrocardiogram, ECG, in an ambulance can improve a patient's chance of surviving a heart attack. An ECG is a simple test that records the rhythm and electrical activity of the heart.

Researchers found that the number of patients who died within 30 days of hospital admission was significantly lower among those who were given an ECG in the ambulance. These patients were also more likely to get treatment to repair a blocked artery.

The study published in the journal Heart also revealed that about a third of patients admitted to hospital with a heart attack are not having the test in the ambulance.
