Tachyarrhythmia

Tachyarrhythmia is a condition characterized by an abnormally fast heart rhythm, typically over 100 beats per minute. It is a type of cardiac arrhythmia and can be life-threatening if not treated promptly.

Types

There are several types of tachyarrhythmias, including:

• Supraventricular tachycardia (SVT): This type of tachyarrhythmia originates in the atria or AV node. It includes conditions such as atrial fibrillation, atrial flutter, and paroxysmal supraventricular tachycardia (PSVT).

• Ventricular tachycardia (VT): This type of tachyarrhythmia originates in the ventricles and can be life-threatening. It includes conditions such as torsades de pointes and ventricular fibrillation.

Symptoms

Symptoms of tachyarrhythmia can vary depending on the type and severity of the condition. They may include:

• Palpitations
• Dizziness
• Shortness of breath
• Chest pain
• Fainting (syncope)

Diagnosis

Tachyarrhythmia is typically diagnosed through a combination of medical history, physical examination, and diagnostic tests such as an electrocardiogram (ECG) or Holter monitor.

Treatment

Treatment for tachyarrhythmia depends on the type and severity of the condition. It may include:

• Medication
• Cardioversion
• Catheter ablation
• Implantable cardioverter-defibrillator (ICD)
