What is the rate of ventricular tachycardia?

As a medical professional with expertise in cardiology, I can provide you with an explanation of the rate of ventricular tachycardia (VT). Ventricular tachycardia is a type of supraventricular tachycardia, which is a rapid heart rate that originates below the ventricles of the heart. The rate of VT is typically greater than 100 beats per minute (bpm), but it can vary depending on the individual case and the specific type of VT. In a normal heart rhythm, the ventricles beat about 60 to 100 times per minute. When VT occurs, the ventricles may beat at a rate of 150 to 250 bpm or even higher. This rapid rate can prevent the heart from filling with enough blood, which can lead to inadequate blood flow to the body and potentially life-threatening conditions. It's important to note that the rate of VT can be sustained or non-sustained. Non-sustained VT lasts for less than 30 seconds and usually does not require treatment, while sustained VT lasts for more than 30 seconds and may require medical intervention. Treatment for VT depends on the underlying cause, the severity of the symptoms, and the patient's overall health. It may include medication, lifestyle changes, or procedures such as a cardioversion or the implantation of a defibrillator.

A normal resting heart rate is 60 to 100 beats per minute. Ventricular tachycardia starts in the heart's lower chambers. Most patients who have ventricular tachycardia have a heart rate that is 170 beats per minute or more.
