Non-drug treatments for paroxysmal ventricular tachycardia (PVT) include:
1. Vagal maneuvers:
These maneuvers stimulate the vagus nerve and can help terminate PVT episodes. Examples include bearing down as if having a bowel movement, coughing forcefully, or immersing the face in ice-cold water.
2. Cardioversion:
This procedure involves delivering an electric shock to the heart to restore normal rhythm. It can be done externally using paddles or internally through catheters placed in the heart.
3. Radiofrequency ablation:
This is a minimally invasive procedure that uses heat energy to destroy the abnormal electrical pathways causing PVT. A catheter is guided to the heart and radiofrequency energy is delivered to target and eliminate the abnormal tissue.
4. Implantable cardioverter-defibrillator (ICD):
An ICD is a small device implanted under the skin that continuously monitors heart rhythm. If it detects PVT, it delivers an electric shock to restore normal rhythm.
5. Catheter ablation:
Similar to radiofrequency ablation, this procedure uses a catheter to deliver energy (such as radiofrequency or cryoablation) to destroy the abnormal tissue causing PVT.
6. Surgical intervention:
In rare cases where other treatments are ineffective, surgery may be considered. Procedures like maze surgery or ventricular aneurysmectomy can be performed to correct underlying structural abnormalities contributing to PVT.
It's important for individuals with PVT to consult with a healthcare professional who can assess their specific condition and recommend appropriate treatment options based on their medical history and individual needs.
