Ventricular tachycardia (V-tach)

This is some text inside of a div block.

Ventricular tachycardia (V-tach) is a type of abnormal heart rhythm that originates in the heart's lower chambers, known as the ventricles. It is characterized by a rapid heart rate of more than 100 beats per minute and is usually caused by an electrical problem in the heart. V-tach can be life-threatening and requires immediate medical attention.

Various factors, including coronary artery disease, heart attack, heart failure, electrolyte imbalances, and certain medications, can cause V-tach. In addition, an underlying heart condition, such as cardiomyopathy or arrhythmogenic right ventricular dysplasia, can also cause it.

V-tach can cause various symptoms, including chest pain, shortness of breath, lightheadedness, dizziness, and fainting. It can also lead to cardiac arrest and sudden cardiac death.

Treatment for V-tach depends on the underlying cause. Medications, such as beta-blockers and antiarrhythmic drugs, may slow the heart rate and restore a normal rhythm. In some cases, an implantable cardioverter defibrillator (ICD) may be necessary to shock the heart back into a normal rhythm. In some cases, surgery may be necessary to correct the underlying cause of the V-tach.

It is important to seek medical attention if you experience any symptoms of V-tach. Early diagnosis and treatment can help prevent serious complications and even death.
