Atrial fibrillation (AF) where the heart's natural pacemaker
runs amok and causes the heart's upper chamber to contract irregularly and fast.
They do this by affecting the SA node, the heart's natural pacemaker
This depolarizes a critical mass of the heart muscle, terminates the dysrhythmia and allows normal sinus rhythm to be reestablished by the body's natural pacemaker
, in the sinoatrial node of the heart.

Other cardiac rhythm-associated research interests at Cornel l have included inherited ventricular arrhythmias in German Shepherds and the mechanism of sick sinus syndrome- a condition in which a dog's natural pacemaker
in the heart (the sinus node) fails to discharge, resulting in inappropriately slow heart rates in affected dogs.
Your heartbeat depends on a natural pacemaker
, a small cluster of cells -- it's about the size of a peppercorn, Marban says -- that generates electrical activity.
It occurs when the heart's natural pacemaker
, which controls the rhythmic physiological activity, develops abnormal rate or rhythm and interrupts the normal condition.
Most of these medications slow the heart rate, either by calming the sinus node, the body's natural pacemaker
, or by slowing down the electrical activity in the heart.
The father-of-two suffers from atrial fibrillation, where abnormal electrical impulses override the heart's natural pacemaker
causing its upper chambers to beat in an unusual rhythm.
Atrial fibrillation occurs when abnormal electrical impulses override the heart's natural pacemaker
The sick sinus syndrome is described as an abnormality in the formation of the electric impulse in the heart, preventing the correct natural pacemaker
function of the sinus node.
Normally, your heartbeat is controlled by the sinus node, the heart's natural pacemaker
