Arrhythmias (Heart Rhythm Disorders) Facts and definition of arrhythmias (heart rhythm disorders) 1  A heart rhythm disorder is an abnormal variation from the normal heartbeat. Heart rhythm disorders involve abnormalities of one or more of the following: heart rate, regularity of beats, sites where electrical impulses originate, or sequence of activation of heartbeats. Heart rhythm disorder is also referred to as an arrhythmia.

- Normal sinus rhythm (NSR) is the characteristic rhythm of the healthy human heart. NSR is the rhythm that originates from the sinus node.The rate in NSR is generally regular but will vary depending on autonomic inputs into the sinus node.ormal sinus rhythm (NSR) is the characteristic rhythm of the healthy human heart. NSR is the rhythm that originates from the sinus node.

Medical Definition of Sinus rhythm Sinus arrhythmia: The normal increase in heart rate that occurs during inspiration (when you breathe in). This is a natural response and is more accentuated in children than adults. The sinus refers to the natural pacemaker of the heart which is called the sinoatrial (or sinus) node. It is located in the wall of the right atrium (the right upper chamber of the heart). Normal cardiac impulses start there and are transmitted to the atria and down to the ventricles (the lower chambers of the heart).

echo beat reciprocal beat a heartbeat resulting from an atrial or ventricular complex caused by a return of an impulse to its chamber of origin; called also echo beat. sinus beat a heartbeat with sinus rhythm. ventricular beat an ectopic beat originating in a ventricle.

Atrioventricular nodal reentry tachycardia (AVNRT) Atrioventricular nodal reentry tachycardia (AVNRT) Atrioventricular nodal reentry tachycardia (AVNRT) is the most common type of supraventricular tachycardia. Episodes often start and end suddenly, and occur because of a reentrant circuit — also called an accessory pathway — located in or near the AV node that causes the heart to beat prematurely. AVNRT tends to occur more often in young women, but it can affect both males and females of any age.

- Re-entry (such as AV nodal reentrant tachycardia and atrioventricular reciprocating tachycardia) often presents with an almost immediate increase in heart rate. Someone experiencing this type of PSVT may feel the heart rate accelerate from 60 to 200 beats per minute or more.

Overview Nonstress test. Overview. A nonstress test (NST), also known as fetal heart rate monitoring, is a common prenatal test used to check on a baby's health. During a nonstress test a baby's heart rate is monitored to see how it responds to the baby's movements. The term nonstress refers to the fact that nothing is done to place stress on the fetus during the test. Typically, a nonstress test is recommended when it's believed that the fetus is at increased risk of death.

Sinus rhythm Sinus rhythm refers to any cardiac rhythm where depolarisation of the cardiac muscle begins at the sinus node.It is characterised by the presence of correctly-oriented P waves on the electrocardiogram (ECG). Sinus rhythm is necessary, but not sufficient, for normal electrical activity within the heart.inus rhythm refers to any cardiac rhythm where depolarisation of the cardiac muscle begins at the sinus node.

- Normal Sinus Rhythm. Description. A normal heart rhythm is called normal sinus rhythm (NSR for short). An NSR will have a heart rate (this is the same as the pulse) between 50 and 100 beats per minute and a normal impulse formation from the SA node ( P wave).

Rhythm Strips Interpretation: A Step-by-Step Approach Nodal The nodal region. . This region is believed to be primarily responsible for the initiation of junctional escape rhythm. These pathways are responsible for the mechanism of AV nodal reentry. It consists of a network of specialized cardiac muscle fibers. AV nodal fibers consist of the slow posterior pathway and the fast anterior pathway.

Cardiology Teaching Package Sinus Arrhythmia, or regularly irregular sinus rhythm, is a variation on sinus rhythm where the P-P interval ( the distance between consecutive P waves) varies by more than 10%. It can be naturally occurring or due to heart damage.

Arrhythmias Definition. 1  An arrhythmia is an abnormality in the heart's rhythm, or heartbeat pattern. The heartbeat can be too slow, too fast, have extra beats, skip a beat, or otherwise beat irregularly. 2  Arrhythmias are deviations from the normal cadence of the heartbeat, which cause the heart to pump improperly.

Atrial Tachycardia Reentrant atrial tachycardia is not uncommon in patients with a history of a surgically repaired atrial septal defect. The scar tissue in the atrium may give rise to the formation of a reentrant circuit. On physical examination, the primary abnormal finding is a rapid pulse rate.eentrant atrial tachycardia is not uncommon in patients with a history of a surgically repaired atrial septal defect.
