Latest Cardiac pacemaker Stories
A new batteryless cardiac pacemaker based on an automatic wristwatch and powered by heart motion was presented at ESC Congress 2014 today by Adrian Zurbuchen from Switzerland. The prototype device does not require battery replacement.
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.
Cardiologists from The Cedars-Sinai Heart Institute in Los Angeles have announced the development of a biologically-based pacemaker by reprogramming ordinary heart cells using the introduction of a single gene - Tbx18.
The heartbeat is the result of rhythmic contractions of the heart muscle, which are in turn regulated by electrical signals called action potentials.
A new technique that stimulates heart muscle cells with low-energy light raises the possibility of a future light-controlled pacemaker, according to this study.
An international team of molecular scientists have discovered that star ascidians, also known as sea squirts, have pacemaker cells similar to that of the human heart.
Pacemaker cells in the sinoatrial node control heart rate, but what controls the ticking of these pacemaker cells?
Scientists in the Hotchkiss Brain Institute at the Faculty of Medicine, University of Calgary, have discovered a new mechanism that nerve cells (neurons) use to fine-tune their electrical output.
Scientists studying genetic data from nearly 50,000 people have uncovered several DNA sequence variations associated with the electrical impulses that make the heart beat.
