Paroxysmal tachycardia
Paroxysmal Tachycardia
Paroxysmal tachycardia (/pærɒksɪzməl tækɪˈkɑːrdiə/) is a type of arrhythmia characterized by sudden onset and termination of rapid heart rate. The term is derived from the Greek words 'paroxysmos' meaning 'irritation' and 'tachycardia' meaning 'rapid heart rate'.
Definition
Paroxysmal tachycardia is a condition where the heart suddenly starts beating at a high rate, typically over 100 beats per minute, and can last from a few seconds to several hours. The rapid heart rate can start and stop abruptly, often for no apparent reason.
Types
There are two main types of paroxysmal tachycardia: Paroxysmal Supraventricular Tachycardia (PSVT) and Paroxysmal Ventricular Tachycardia (PVT). PSVT originates in the atria or AV node, while PVT originates in the ventricles.
Symptoms
Common symptoms of paroxysmal tachycardia include palpitations, shortness of breath, chest pain, dizziness, and fainting. However, some people may not experience any symptoms.
Causes
The exact cause of paroxysmal tachycardia is often unknown. However, it can be triggered by certain factors such as stress, caffeine, alcohol, and certain medications. It can also be associated with certain medical conditions like heart disease, hypertension, and thyroid disease.
Treatment
Treatment for paroxysmal tachycardia depends on the type, severity of symptoms, and overall health of the patient. It may include medications, lifestyle changes, and in some cases, procedures like catheter ablation.
