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.
There is more chance of a heart attack. A pacemaker regulates the patients 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.
In most cases, ventricular dysfunction can be helped with medication or a pacemaker. However, a true fix is surgery but it is not always successful.

The Pacemaker ensures that the heart has a steady rhythm without any cause for a breakdown or skip in the beat.
Pacemaker (sinoatrial node)
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.
An artificial pacemaker
The pacemaker will regulate the heartbeat, and a regulated heartbeat will regulate the speed blood is moved throughout the body. Improved blood flow, especially in the legs, will improve general health across the board.
Pacemaker
A weak and slow heartbeat can be caused by conditions such as heart block, sick sinus syndrome, or electrolyte imbalances. It can also be a side effect of certain medications or a result of aging. It's important to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
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.
