The heart is made up of many cardiomyocytes, or cardiac muscle cells, that contract in response to electrical stimulation to produce the heart beat. It is vitally important for the cardiomyocytes to coordinate their contractions, so tha...

The normal heart rhythm, known as sinus rhythm, originates in specialized cardiac cells, called pacemaker cells, in the sino-atrial (SA) or sinus node and has been defined as a sinus node rate of 60 to 100 beats/minute. Each heart beat or contraction is initiated by generation of an ...
PURPOSE: To provide a cardiac pacemaker having desired features such as physiological responsiveness, quick responsiveness, long-time reliability and high-grade limitedness by sensing blood pressure and controlling the frequency of heartbeats corresponding to this blood pressure. CONSTITUTION: A pulse ...
The natural pacemaker of the heart is made of cardiac muscle tissue that stimulates other cardiac muscle cells to contract. Because of its self-stimulation, cardiac muscle is considered to be autorhythmic or intrinsically controlled. The cells of cardiac muscle tissue are striated---that is, they...
The sinoatrial (SA) nodes are areas of the heart's atrium that act as the heart's pacemaker. Impulses from the SA node cause the heart’s chambers to contract. Purkinje fibers receive their impulses from the SA node and move the impulse through the heart’s muscles. Just below the atrium...
At a cellular level, the high-level hardware encased in our skulls is at a structural sweet spot closely approaching a phase transition. A common feature of this critical point is the branch-like structure of neurons, known as fractal patterns. ...
