About His bundle tachycardia

What is His bundle tachycardia?

His bundle tachycardia is a type of supraventricular tachycardia (SVT) that originates in the bundle of His, a group of specialized fibers that conduct electrical signals from the atria to the ventricles. It is a type of re-entry tachycardia, meaning that the electrical signal is able to travel in a circular loop, causing the heart to beat too quickly.

What are the symptoms of His bundle tachycardia?

The most common symptom of His bundle tachycardia is palpitations, which is a feeling of rapid or irregular heartbeats. Other symptoms may include chest pain, shortness of breath, dizziness, lightheadedness, and fatigue.

What are the causes of His bundle tachycardia?

The most common cause of His bundle tachycardia is an abnormality in the electrical conduction system of the heart. This can be caused by a variety of factors, including congenital heart defects, scarring of the heart muscle due to a heart attack, or inflammation of the heart muscle due to a viral infection. Other causes of His bundle tachycardia include certain medications, electrolyte imbalances, and certain types of heart surgery.

What are the treatments for His bundle tachycardia?

1. Medication: Medications such as beta blockers, calcium channel blockers, and antiarrhythmic drugs may be used to slow the heart rate and reduce symptoms.

2. Ablation: Radiofrequency ablation is a procedure that uses heat to destroy the abnormal electrical pathways that cause the tachycardia.

3. Pacemaker: A pacemaker may be implanted to help regulate the heart rate.

4. Surgery: Surgery may be necessary to repair any underlying structural heart defects that may be causing the tachycardia.

What are the risk factors for His bundle tachycardia?

1. Structural heart disease
2. Congenital heart defects
3. Cardiac surgery
4. Abnormalities of the conduction system
5. Certain medications
6. Excessive alcohol consumption
7. Smoking
8. Stress
9. Hyperthyroidism
10. Electrolyte imbalances

Is there a cure/medications for His bundle tachycardia?

Yes, there are medications and treatments available for His bundle tachycardia. Medications such as beta blockers, calcium channel blockers, and antiarrhythmic drugs can be used to slow the heart rate and reduce symptoms. Other treatments such as radiofrequency ablation, cryoablation, and pacemaker implantation may also be used to treat the condition.
