Icelandic Cardiologists Make Notable Discovery

A team of scientists from Hjartavernd, the Icelandic Heart Association, in cooperation with a team of scientists from Europe and the US have discovered nine gene regions associated with the heart’s system of conducting electrical impulses that control contractions of the heart.

The discovery is described as an important milestone in medicine, Fréttabladid reports.

The conclusions of their research might open new possibilities to predict irregular heart beat frequently associated with stroke and could potentially be used for preventive medicine.

The findings were recently described in an article “Genome-wide association study of PR interval” published in the respected science journal Nature Genetics.

The heart’s inner electrical conducting system has been researched with electrocardiogram (ECG; EKG) for more than 100 years, which is among the most important tools in general medicine.

More in-depth knowledge of the factors that control the heart’s electrical impulse system and its contraction opens new possibilities to examine serious hearth rhythm disturbances like atrial fibrillation.

Five of the gene regions that were found in the genome are related to normal contractions in the heart but also atrial fibrillation.
