Final answer:
Pulseless ventricular tachycardia (VT) is a life-threatening cardiac rhythm disturbance characterized by a rapid, regular heartbeat in the ventricles without a pulse. Identifying pulseless VT involves clinical assessment and electrocardiogram (ECG) findings. Treatment includes immediate CPR and defibrillation using AEDs or ACLS protocols.
Step-by-step explanation:
Pulseless ventricular tachycardia (VT) is a life-threatening cardiac rhythm disturbance characterized by a rapid, regular heartbeat in the ventricles without a pulse. It is considered an emergency situation as it can lead to cardiac arrest and cessation of blood circulation.
To identify pulseless VT, healthcare providers typically rely on clinical assessment and electrocardiogram (ECG) findings. The ECG will show a wide QRS complex with a heart rate greater than 100 beats per minute. Since there is no pulse, the patient will present with symptoms such as loss of consciousness, cyanosis, and absence of carotid pulses.
Treatment for pulseless VT includes immediate cardiopulmonary resuscitation (CPR) and defibrillation, which delivers an electrical shock to the heart to restore normal rhythm. This can be done using automated external defibrillators (AEDs) found in many public places or advanced cardiac life support (ACLS) protocols in a hospital setting.
