Atrial fibrillation is a condition that causes a
rapid and irregular heartbeat. The normal heart rate lies between 60 and 100 beats per minute.
Many suspect Van Gogh suffered from foxglove extract overdose due to the yellow halos in his paintings and his portrait of his physician holding the plant.
The risk of developing an irregular heartbeat was 41% higher among those who were grieving a partner's loss than among those who hadn't experienced such loss. And this could last up to a year.
