Hello, I'm an expert in medical terminology and procedures. When it comes to "shock V tach," it's important to clarify that "shock" in a medical context can refer to a treatment method, specifically defibrillation, which is used to correct certain life-threatening abnormal heart rhythms, such as Ventricular Tachycardia (V tach). Defibrillation involves passing an electric current through the heart to reset its normal rhythm. This is typically done using a defibrillator, which can be either manual or automated (AED). In English: Ventricular Tachycardia (V tach) is a rapid heart rate that originates in the ventricles of the heart. It is a serious condition that can lead to cardiac arrest if not treated promptly. In cases of V tach, synchronized cardioversion, which is a form of shock, may be administered to restore the heart's normal rhythm. This procedure is called "shocking V tach" and it involves delivering an electrical shock to the heart in a controlled manner. It's crucial that this is done by trained medical professionals using appropriate equipment. In Chinese: 室性心动过速（V tach）是起源于心脏室性的一种快速心率。这是一种严重的状况，如果不及时治疗，可能会导致心脏骤停。在V tach的情况下，可能会施行同步电复律，这是一种电击形式，以恢复心脏的正常节律。这个过程被称为“电击V tach”，涉及以控制的方式向心脏提供电击。重要的是，这必须由使用适当设备的受过训练的医疗专业人员来执行。 read more >>

Pulseless VT. Pulseless VT, in contrast to other unstable VT rhythms, is treated with immediate defibrillation. High-dose unsynchronized energy should be used. The initial shock dose on a biphasic defibrillator is 150-200 J, followed by an equal or higher shock dose for subsequent shocks.read more >>
