Cardiac Arrhythmia (C0003811)

Definition (MEDLINEPLUS)

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.

Definition (SNOMEDCT_US) Abnormality in rhythm of heartbeat, including rate, regularity, and/or sequence of activation abnormalities
Definition (SNOMEDCT_US) Abnormality in rhythm of heartbeat, including rate, regularity, and/or sequence of activation abnormalities
Definition (SCTSPA) Anomalía del ritmo cardíaco, que incluye alteraciones de la frecuencia, de la regularidad y/o de la secuencia de activación.
Definition (NCI_NICHD) Cardiac Arrhythmias are heart-rhythm problems - they occur when the electrical impulses to the heart that coordinate heartbeats are not working properly, making the heart beat too fast/slow or inconsistently.
Definition (NCI) Any variation from the normal rate or rhythm (which may include the origin of the impulse and/or its subsequent propagation) in the heart.
Definition (SNOMEDCT_US) A disorder in which there is abnormal electrical activity in the heart.
Definition (CSP) any variation from the normal rhythm or rate of the heart beat.
Definition (MSH) Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction.
