Ventricular tachycardia is different from atrial tachycardia in that atrial tachycardia originates in the atria and ventricular tachycardia originates in the ventricles. Atrial tachycardia is often associated with coronary artery disease, myocarditis, digitalis toxicity, hyperthyroidism, and agitation, and the heart rate is usually 150-200 beats per minute during the attack. Ventricular tachycardia also has organic lesions, such as hypertension, heart disease, coronary artery disease, and end-stage rheumatic heart disease, and the frequency is mostly 150-250 beats per minute, and it is mostly manifested as wide and malformed QRS waves, which are very risky. The presence of ventricular tachycardia, regardless of the disease causing it, requires active resuscitation and complete access to resuscitation. In addition, amiodarone therapy is administered, pushed if necessary, and electrical cardioversion is performed if the medication is not effective. Tachycardia or ventricular tachycardia or ventricular fibrillation should be actively resuscitated.
