As a medical professional with expertise in cardiology, I can provide you with information on ventricular tachycardia (VT). Ventricular tachycardia is a type of supraventricular tachycardia that originates in the ventricles of the heart and is characterized by a rapid heart rate. The heart rate in ventricular tachycardia is typically over 100 beats per minute (bpm), and it can range from just above 100 bpm to over 250 bpm in extreme cases. The specific rate can vary depending on the individual and the underlying cause of the condition. It's important to note that ventricular tachycardia is a serious medical condition that requires immediate attention, as it can lead to a life-threatening situation such as sudden cardiac arrest if not treated promptly. Now, let's translate that into Chinese: 作为一位在心脏病学领域具有专业知识的医学专家，我可以为您提供有关室性心动过速（VT）的信息。室性心动过速是一种起源于心脏心室的室上性心动过速，其特点是心率迅速。 室性心动过速的心率通常超过每分钟100次（bpm），并且可以从略高于100 bpm到极端情况下超过250 bpm不等。具体的速率可以根据个体和病情的潜在原因而变化。 需要注意的是，室性心动过速是一种严重的医疗状况，需要立即注意，因为如果不及时治疗，它可能导致心脏骤停等危及生命的情况。 read more >>

Tachycardia is a heart rate higher than 100 beats per minute. A normal resting heart rate is 60 to 100 beats per minute. Ventricular tachycardia starts in the heart's lower chambers.read more >>
