The SA (sinus) node represents a cluster of myocytes with pacemaker activity. Under normal circumstances, it generates electrical impulses that set the rhythm and rate of the heart. The mass of the sinus node is too small to create a substantial electrical signal that can be detected on the electrocardiogram (ECG). The ECG output shows the rhythm of the electrical impulses inside the heart.

The other conduction tissue (AV node, bundle of His and Purkinje fibers) will take over as pacemakers in disease states according to their speed of depolarization (AV > bundle of His > Purkinje fibers).

SA node dysfunction (SND) is the second most common indication for cardiac pacemaker implantation (after atrioventricular block), accounting for approximately 28% of cases (Mond et al., 2004). Common symptoms of SND include dizziness, syncope (temporary loss of consciousness), fatigue, and decrease in exercise tolerance.

When multifocal atrial tachycardia occurs, multiple (non-SA) sites are firing impulses. EKG: Rapid irregular rhythm > 100 bpm.

Sinus rhythm requires ALL of the following 3 criteria: · The R-R interval in NSR In order to beat, the heart needs three types of cells: 1. Rhythm generators, which produce an electrical signal (SA node or normal pacemaker);.

Sinoatrial (SA) Exit Block ECG Review - Criteria and Examples In SA exit block, the SA node depolarizes, but conduction of impulses to atrial tissue is impaired. In 1st-degree SA block, the SA node impulse is merely slowed, and ECG is normal. The electocardiogram or ECG is a major diagnostic tool for the assessment of the health of the heart. It is a measurement taken at the surface of the skin which reflects the electrical phenomenain the heart when the SA nodetriggers the electrical sequencethat controls heart action.

2021-02-02 · The ECG output shows the rhythm of the electrical impulses inside the heart. The SA node is a bundle of nerve tissue found in the human heart. This tissue acts as a natural pacemaker and is called by other names as well. Some other words for this node include sinoatrial node, sinus node, or SAN. The sinoatrial node (SA node) The sinoatrial node is a small oval structure located near the entrance of the superior vena cava in the right atrium (Figure 1).

The SA node at rest fires 60 to 100 times in adults per minute and 60 to 190 times per minute in infants and children (depending on the age and level of activity) while the junctional tissue about the AV node (cardiac whether the source of the rhythm is the SA node (sino-atrial) or an ectopic pacemaker. To determine whether the source of the rhythm is "sinus" or an ectopic rhythm, you need to look at the relationship of the P-wave, if present, to the QRS-complex. If there is a P wave before each QRS and the P is in Interpreting EKG Rhythm Strips Step 3 – P Wave P wave is produced when the left and right atria depolarize First deviation from the isoelectric line Should be rounded and upright P wave is the SA node pacing or firing at regular intervals This pattern is referred to as a sinus rhythm Normal cardiac rhythm is established by the sinoatrial (SA) node, a specialized clump of myocardial conducting cells located in the superior and posterior walls of the right atrium in close proximity to the orifice of the superior vena cava. The SA node has the highest inherent rate of depolarization and is known as the pacemaker of the Main Difference.
