Atrial fibrillation is a common but often silent heart condition, especially over 60. Learn the symptoms, risks and why early ...

The results of a study demonstrating how circadian rhythms in heart cells are involved in changing heart function over the course of the day could help to explain why shift workers are more vulnerable ...

Researchers have used the zebrafish (Danio rerio) to identify the role of a gene involved in cardiac rhythm, which could help explain the fundamentals of what it takes to make a human heartbeat.

CLEVELAND - A fundamental discovery reported in the March 1st issue of the journal Nature, uncovers the first molecular evidence linking the body’s natural circadian rhythms to sudden cardiac death ...

Tiny pores in heart cells generate electrical signals to initiate each heart beat. Structural studies of these channels provide details on their functions, and also on their malfunction due to ...

The science of death often seems strange and scary, but there are some trends, including this particular pattern of ...

Researchers have discovered the molecular origins of the heart beat. They have found the proteins that make up tiny sodium channels in the tissues of the heart that can help generate the heart beats.

A fundamental discovery reported in the March 1 issue of the journal Nature uncovers the first molecular evidence linking the body’s natural circadian rhythms to sudden cardiac death (SCD).
