As a medical professional with expertise in emergency medicine, I can provide you with an informed answer to your question regarding Ventricular Tachycardia (V tach). English Answer: Ventricular Tachycardia (V tach) is a type of ventricular arrhythmia characterized by three or more premature ventricular contractions in a row, with a rate typically over 100 beats per minute. Whether V tach is considered a shockable rhythm depends on the clinical context and the specific type of V tach present. There are two main categories: 1. Pulseless V tach: This is a life-threatening emergency where the heart is pumping ineffectively or not at all, and the patient has no pulse. It is considered a shockable rhythm because the goal of defibrillation is to convert the V tach back to a normal sinus rhythm or a slower, more organized rhythm that can maintain a pulse. 2. V tach with a pulse: In this situation, the patient has a pulse, and the heart is functioning effectively enough to maintain circulation. This type of V tach is generally not considered a shockable rhythm. Instead, medical treatment typically focuses on controlling the heart rate and rhythm with medications and addressing any underlying causes. It's important to note that the decision to shock a patient with V tach should be made by a healthcare professional who has assessed the patient's condition and determined the most appropriate course of action. 中文回答： 室性心动过速（V tach）是一种室性心律失常，其特征是连续出现三个或更多的室性早搏，频率通常超过每分钟100次。V tach是否被认为是可电击心律取决于临床情况和存在的特定类型的V tach。主要有两个类别： 1. 无脉V tach：这是一种生命威胁的紧急情况，心脏泵血无效或完全不泵血，患者没有脉搏。它被认为是可电击心律，因为除颤的目标是将V tach转换回正常的窦性心律或更慢、更有序的心律，以维持脉搏。 2. 有脉V tach：在这种情况下，患者有脉搏，心脏功能足以维持循环。这种类型的V tach通常不被认为是可电击心律。相反，医疗治疗通常侧重于用药物控制心率和心律，并解决任何潜在的原因。 需要注意的是，决定对V tach患者进行电击应由评估了患者状况并确定了最合适行动方案的医疗专业人员做出。 read more >>

Treatment of Ventricular Fibrillation (VF) and Pulseless Ventricular Tachycardia (VT) is included in the Cardiac Arrest Algorithm. VF and pulseless VT are shockable rhythms and treated in similar fashion. Asystole and PEA are also included in the cardiac arrest algorithm but are nonshockable rhythms.read more >>
