Ventricular tachycardia (VT) is a heart rhythm disorder that originates in the ventricles, the lower chambers of the heart that are responsible for pumping blood. This condition is often caused by scar tissue in the heart that creates abnormal electrical pathways in the ventricles, causing the heart to beat rapidly. This can lead to ineffective pumping of blood and reduced blood flow to vital organs.
VT is often caused by the presence of scar tissue in the heart from previous heart attacks or heart inflammation. Electrolyte imbalances, heart attack, congenital heart disease, and cardiomyopathy may also cause VT.
Symptoms of Ventricular Tachycardia
The rapid heartbeat caused by VT may lead to rapid or fluttering heartbeats (palpitations), shortness of breath, chest pain, fainting (syncope), and loss of consciousness. Some patients are at higher risk, which can lead to sudden cardiac death. A more in-depth evaluation of this risk is necessary.
Diagnosing Ventricular Tachycardia
VT is diagnosed through a combination of clinical assessment, which includes a review of family health history; electrocardiographic (ECG) findings; and additional testing. Diagnosis may include the use of:
- Electrocardiogram (ECG or EKG): VT is identified by rapid heart rates of usually over 100 beats per minute
- Echocardiogram
- Cardiac MRI: used to assess the heart's structure and rule out underlying causes, such as scarring or cardiomyopathies
- Holter monitor: used to detect VT episodes
- Genetic testing: used to identify specific genes that could be responsible for the condition
Ventricular Tachycardia Treatment at Valley
Each patient in the Ventricular Arrhythmia Program receives a personalized treatment plan designed to meet their specific needs. Treatment for VT varies based on the underlying cause and the severity of the condition.
