Clinical Information

• Postural Orthostatic Tachycardia Syndrome

  a syndrome of orthostatic intolerance combined with excessive upright tachycardia, and usually without associated orthostatic hypotension. all variants have in common an excessively reduced venous return to the heart (central hypovolemia) while upright.

• Tachycardia

  abnormally rapid heartbeat, usually with a heart rate above 100 beats per minute for adults. tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia.

• Tachycardia, Atrioventricular Nodal Reentry

  abnormally rapid heartbeats caused by reentry of atrial impulse into the dual (fast and slow) pathways of atrioventricular node. the common type involves a blocked atrial impulse in the slow pathway which reenters the fast pathway in a retrograde direction and simultaneously conducts to the atria and the ventricles leading to rapid heart rate of 150-250 beats per minute.

• Tachycardia, Ectopic Atrial

  abnormally rapid heartbeats originating from one or more automatic foci (nonsinus pacemakers) in the heart atrium but away from the sinoatrial node. unlike the reentry mechanism, automatic tachycardia speeds up and slows down gradually. the episode is characterized by a heart rate between 135 to less than 200 beats per minute and lasting 30 seconds or longer.

• Tachycardia, Ectopic Junctional

  a rare form of supraventricular tachycardia caused by automatic, not reentrant, conduction initiated from sites at the atrioventricular junction, but not the atrioventricular node. it usually occurs during myocardial infarction, after heart surgery, or in digitalis intoxication with a heart rate ranging from 140 to 250 beats per minute.

• Tachycardia, Paroxysmal

  abnormally rapid heartbeats with sudden onset and cessation.

• Tachycardia, Reciprocating

  abnormally rapid heartbeats caused by reentrant conduction over the accessory pathways between the heart atria and the heart ventricles. the impulse can also travel in the reverse direction, as in some cases, atrial impulses travel to the ventricles over the accessory pathways and back to the atria over the bundle of his and the atrioventricular node.

• Tachycardia, Sinoatrial Nodal Reentry

  abnormally rapid heartbeats caused by reentry circuit in or around the sinoatrial node. it is characterized by sudden onset and offset episodes of tachycardia with a heart rate of 100-150 beats per minute. the p wave is identical to the sinus p wave but with a longer pr interval.

• Tachycardia, Sinus

  simple rapid heartbeats caused by rapid discharge of impulses from the sinoatrial node, usually between 100 and 180 beats/min in adults. it is characterized by a gradual onset and termination. sinus tachycardia is common in infants, young children, and adults during strenuous physical activities.

• Tachycardia, Supraventricular

  a generic expression for any tachycardia that originates above the bundle of his.

• Tachycardia, Ventricular

  an abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. it is generated within the ventricle below the bundle of his, either as autonomic impulse formation or reentrant impulse conduction. depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide qrs complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (av dissociation).

• Heart Rate

  the number of times the heart ventricles contract per unit of time, usually per minute.

• Sinoatrial Node

  the small mass of modified cardiac muscle fibers located at the junction of the superior vena cava (vena cava, superior) and right atrium. contraction impulses probably start in this node, spread over the atrium (heart atrium) and are then transmitted by the atrioventricular bundle (bundle of his) to the ventricle (heart ventricle).

• Bundle of His

  small band of specialized cardiac muscle fibers that originates in the atrioventricular node and extends into the membranous part of the interventricular septum. the bundle of his, consisting of the left and the right bundle branches, conducts the electrical impulses to the heart ventricles in generation of myocardial contraction.

• Ectopic Atrial Tachycardia

  a disorder characterized by an electrocardiographic finding of atrial tachycardia that does not originate from the sinoatrial node.

• Congenital Bundle of His Tachycardia|Congenital His Bundle Tachycardia|Junctional Ectopic Tachycardia, Congenital

  a congenital disorder characterized by an electrocardiographic finding of tachycardia that affects neonates and infants. it results from an increased automaticity in the atrioventricular node and his bundle.

• Junctional Ectopic Tachycardia

  a tachycardia originating in or adjacent to the av junction.

• Atrial Tachycardia

  a disorder characterized by an electrocardiographic finding of an organized, regular atrial rhythm with atrial rate between 101 and 240 beats per minute. the p wave morphology must be distinct from the sinus p wave morphology. (cdisc)

Patient Education

Arrhythmia

An arrhythmia is a problem with the rate or rhythm of your heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia. When the heart beats too slowly, it is called bradycardia. The most common type of arrhythmia is atrial fibrillation, which causes an irregular and fast heart beat.

Many factors can affect your heart's rhythm, such as having had a heart attack, smoking, congenital heart defects, and stress. Some substances or medicines may also cause arrhythmias.

Symptoms of arrhythmias include:

• Fast or slow heart beat
• Skipping beats
• Lightheadedness or dizziness
• Chest pain
• Shortness of breath
• Sweating

Your doctor can run tests to find out if you have an arrhythmia. Treatment to restore a normal heart rhythm may include medicines, an implantable cardioverter-defibrillator (ICD) or pacemaker, or sometimes surgery.
