The SA node begins the heartbeat and is sometimes referred to as the heart's pacemaker.
The AV node are where the electrical impulses are delayed for 0.1 second before spreading to both ventricles and causing them to contract.

What happens without a pacemaker?
There is more chance of a heart attack. A pacemaker regulates the patients heartbeat.
Sensitive tissue in the right atrium that begins the heartbeat?
Pacemaker (sinoatrial node)
Which valve controls the heartbeat?
Valves have nothing to do with heart beat The pacemaker of the heart controls the heart beat
What does a pacemaker control in the heart?
A pacemaker sends electrical shocks to the heart to beat it at a particular speed. It pulsates the heart at a set rate (eg. 60bpm) to help those who are have a slower than normal heartbeat.
What is the relationship between the heartbeat and the pacemaker?
The Pacemaker ensures that the heart has a steady rhythm without any cause for a breakdown or skip in the beat.
Where does the spark that begins your heartbeat originate?
The normal heartbeat begins as an electrical impulse in the sino-atrial node (or SA node). The SA node is called the pacemaker of the heart. It is located in the R atrium, just below the entrance of the superior vena cava.
What purpose does an artificial pacemaker serve and does it function?
An artificial pacemaker works by detecting changes in the heart's rhythm. If it detects a 'problem' - it delivers a shock to the heart's muscle - returning the heartbeat to a regular beat.
What does a ventricular pacemaker do to initiate a heartbeat?
The SA node (Sinoatrial node) sets the pace for the heart as a whole because no other region of the conduction system or the myocardium has a faster depolarization rate. For this reason, it is the heart's pacemaker.
What is a word that begins with the heart?
Heartache, heartbeat, heartbreak, heartburn and heartthrob are words. They begin with the letters heart.
Who would use heart pacemaker?
There are several criteria that a sick person must meet before they are eligible for a pacemaker. Specifically, they must have severe heart problems, delayed heartbeat, and be on medications to treat their heart problems.
Why you call SA node as pacemaker?
The SA node normally functions as the pacemaker for the entire heart because its intrinsic rate is the fastest in the system. From the SA node, impulses spread out over the atria, causing them to contract.
What device would be used to regulate a heartbeat?
A pacemaker is a device that is commonly used to regulate an irregular heartbeat by sending electrical impulses to the heart to help it maintain a normal rhythm.
