As we age, our maximum heart rate (maxHR) decreases - limiting the performance of aging athletes. Decreased maxHR is also a leading cause for nursing home admittance for otherwise-healthy elderly individuals who no longer have the physical capacity required for independent living.
Arrhythmia is a potentially life-threatening problem with the rate or rhythm of the heartbeat, causing it to go too fast, too slow or to beat irregularly.
The heartbeat is the result of rhythmic contractions of the heart muscle, which are in turn regulated by electrical signals called action potentials.
Pacemaker cells in the sinoatrial node control heart rate, but what controls the ticking of these pacemaker cells?
New research in the Journal of General Physiology helps explain how the body's "flight-or-fight" response is mediated.
Scientists at The University of Manchester have solved a mystery connected with why people die from sudden cardiac arrest during sleep â€“ potentially saving thousands of lives.
Artificial heart pacemakers have saved and extended the lives of thousands of people, but they have their shortcomings â€“ such as a fixed pulse rate and a limited life. Could a permanent biological solution be possible?
