German scientists say that a person can be diagnosed with depression by monitoring their heart rate. The study was presented by German experts at the 33rd Annual (Virtual) Congress held online by the European College of Neuropsychopharmacology.
Dr. Carmen Schwick and his colleagues at Goethe University, Frankfurt, have discovered that depression can be diagnosed with 90% accuracy based on heart rate fluctuations over a full 24 hours. Previous research has shown that depression affects the human heart rate, but it is not known what the nature of this relationship is. A recent study has done the same thing.
During the study, patients with depression were given the sedative “Ketamine”, which reduces nerve stress and reduces the severity of depression. However, this drug is prescribed only in extreme cases. All volunteers in the study were constantly monitored for heart rate.
The volunteers wore light ECG devices on their wrists to monitor their heartbeat 24 hours a day, which lasted for four days and three nights. In the next step, the data was analyzed on a special computer program equipped with artificial intelligence.
While this analysis found that patients with depression had slightly higher heart rates than healthy people, they also found that the higher the severity of depression, the higher the heart rate during a 24-hour period. There will be less change.
According to experts, these findings also suggest that heartbeat-assisted depression can be diagnosed before symptoms appear. The effectiveness of anti-depressant drugs can be tested in one to two days instead of weeks and months.
