What does the medical term dysrhythmia mean?
Both arrhythmia and dysrhythmia refer to an abnormal rhythm of your heartbeat. If you experience an arrhythmia, the rhythm of your heartbeat is too fast or too slow.
What is a dysrhythmia in the heart?
An arrhythmia (also called dysrhythmia) is an irregular or abnormal heartbeat.
What are some examples of Dysrhythmias?
Some additional examples of supraventricular arrhythmias include:
- Atrial flutter. Atrial flutter is similar to atrial fibrillation in that the atria beat faster than the ventricles, causing the upper and lower chambers of your heart to be out of sync.
- Atrial premature complex (PAC).
- Atrial paroxysmal tachycardia (PAT).
Is there a difference between a dysrhythmia and an arrhythmia?
The terms dysrhythmia and arrhythmia differ mainly in a linguistic sense. “Dys” is a Greek prefix that means bad, ill, hard, or difficult. “A” is another Greek prefix that generally means not or without. Therefore, dysrhythmia essentially means “bad rhythm,” and arrhythmia basically means “without rhythm.”
What can cause cardiac dysrhythmias?
Things that may increase the risk of heart arrhythmias include:
- Coronary artery disease, other heart problems and previous heart surgery.
- High blood pressure.
- Congenital heart disease.
- Thyroid disease.
- Obstructive sleep apnea.
- Electrolyte imbalance.
- Certain drugs and supplements.
- Excessive alcohol.
Is sinus tachycardia a dysrhythmia?
Sinus tachycardia should be considered a physiological reflex rather than a true dysrhythmia, but it is an important sign for which the etiology must be sought. Fever, hypovolemia, and anemia all appropriately increase heart rate to at least maintain or increase cardiac output.
Is a heart murmur a cardiac dysrhythmia?
The term heart murmur does not mean an illness or disorder. A murmur is the sound of blood being pumped through the heart’s chambers and valves. A murmur is sometimes, but not always, a sign of an arrhythmia.
Is AFib a dysrhythmia?
Atrial fibrillation (AF) is a form of arrhythmia, or irregular heartbeat, in which the atria (the two small upper chambers of the heart) quiver instead of beating effectively. It is one of the most common forms of cardiac arrhythmia, affecting 0.4% of the general population and 5 to 10% of persons over 65 years of age.
What are the most important clinical signs and symptoms of Dysrhythmias?
Symptoms, Diagnosis and Monitoring of Arrhythmia
- Fatigue or weakness.
- Dizziness or lightheadedness.
- Fainting or near-fainting spells.
- Rapid heartbeat or pounding in the chest.
- Shortness of breath and anxiety.
- Chest pain or pressure.
- In extreme cases, collapse and sudden cardiac arrest.
What is sinus tachy?
Sinus tachycardia is a regular cardiac rhythm in which the heart beats faster than normal. While it is common to have tachycardia as a physiological response to exercise or stress, it causes concern when it occurs at rest.
