Ventricular tachycardia Treatment in Malaysia

What is Ventricular Tachycardia?

Ventricular tachycardia (VT or V-tach) is a form of arrhythmia or irregular heartbeat. It happens when the heart's lower chamber beats too quickly to pump blood, adequately depriving the body of oxygen.
At rest, a healthy heart beats between 60 and 100 times per minute. The heart beats faster in ventricular tachycardia, typically 100 beats per minute or higher.

What is the Importance of Timely Treatment?

Since ventricular tachycardia (VT) can result in ventricular fibrillation, immediate intervention is essential to avoid potentially fatal consequences such as sudden cardiac arrest.

By preventing blood clots, early intervention lowers the risk of stroke and increases survival rates. Treating the arrhythmia early on also helps avoid long-term heart damage, like heart failure.

Timely therapy can also improve the patient's general quality of life by reducing symptoms like fatigue and dizziness.

What are the Common Symptoms of Ventricular tachycardia?

Ventricular tachycardia symptoms appear due to the oxygen shortage. These could include:

• Angina, or chest pain.
• Lightheadedness.
• Palpitations (pounding heartbeat).
• Dizziness
• Breathlessness.
• Fainting is one sign of sustained V-tach.
• Unconsciousness.
• Sudden death or cardiac arrest.

Even with mild symptoms, ventricular tachycardia can be a medical emergency.

Types of Ventricular Tachycardia

The following terms commonly refer to ventricular tachycardia:

• Monomorphic ventricular tachycardia: An Electrocardiogram (EKG) can detect monomorphic ventricular tachycardia, a heart rhythm accounting for 70% of all VT occurrences, as indicated by a consistent wave on the machine.
• Polymorphic ventricular tachycardia: This kind of arrhythmia is quite harmful. The term "poly" refers to the widespread electrical activity of your heart. Depending on the type of polymorphic VT you have, you might require a different kind of medication or treatment.
• Nonsustained ventricular tachycardia: When VT lasts less than 30 seconds, it is called nonsustained ventricular tachycardia.
• Sustained ventricular tachycardia: When a VT episode lasts 30 seconds or more or results in an issue requiring medical attention, such as a sudden decrease in blood pressure, it is called sustained VT.
• Pulseless ventricular tachycardia: When you have this kind of VT, your ventricles beat too quickly to fill with blood and pump it throughout your body. If your heart cannot maintain a regular blood flow, you will not have a pulse.

Causes, Risk Factors and Complications of Ventricular Tachycardia

Causes

Ventricular tachycardia can be brought on by various factors that interfere with cardiac signals. These consist of:

• Previous heart attack.
• Structural heart disease is any cardiac problem that results in tissue scarring.
• Coronary artery disease, which results in inadequate blood supply to the heart muscle.
• Heart issues, such as long QT syndrome, are present from birth.
• variations in the electrolyte levels in the body. These consist of calcium, magnesium, sodium, and potassium.
• Adverse medication reactions.
• Use of stimulants

Risk Factors

Ventricular tachycardia is more likely to occur in any condition that strains the heart or damages cardiac tissue. Changing one's lifestyle to include healthier eating and quitting smoking may reduce the risk. Getting the proper medical care is also crucial if you suffer from any of the following illnesses or circumstances:

• Heart condition.
• Side effects of medicines
• Severe variations in the body's mineral levels are known as electrolyte imbalances.
• A history of stimulant medication use
• Ventricular tachycardia is also more common in people with a family history of tachycardia or other heart rhythm abnormalities.

Complications

Possible complications of ventricular tachycardia include:

• Ventricular fibrillation
• Frequent episodes of unconsciousness or fainting.
• Heart failure.
• Sudden cardiac arrest-related death.

Latest Research and Technologies in the Treatment of Ventricular Tachycardia in Malaysia

• A cutting-edge method called pulsed field ablation (PFA) uses high-energy electrical pulses to target cardiac tissue while causing the least harm to other locations. This approach has been effectively used in hospitals, significantly advancing in managing arrhythmias.
• Robotic Magnetic Navigation (RMN): This technology improves stability and precision during electrophysiological operations by using magnetic fields to guide catheters. This method, which offers better results in VT ablation treatments, has been incorporated into Malaysia's cardiac care.

Ventricular Tachycardia Prevention Tips

Maintaining a healthy heart is the first step in preventing ventricular tachycardia. If you have heart disease, get regular exams and stick to your treatment plan. Follow the directions on all medications.

• Manage high cholesterol, high blood pressure, and diabetes
• Avoid tobacco use and smoking
• Saturated fat and sodium through diet should be low
• Unless your medical team advises otherwise, try to get in at least 30 minutes of exercise most days of the week
• Get enough rest. Seven to nine hours a day is what adults should strive for
• Keep your weight in check
• Manage and lessen stress
