Final answer:
The missing term in the list consisting of Afib, Aflutter, and _________ as examples of supraventricular tachycardia is 'paroxysmal supraventricular tachycardia', diagnosed through ECG and potentially treated with defibrillation in severe cases.
Step-by-step explanation:
The term that completes the list of examples of supraventricular tachycardia (SVT) alongside Afib and Aflutter is paroxysmal supraventricular tachycardia.
These conditions are types of arrhythmias, which are due to problems with the electrical conduction system of the heart.
The diagnosis of such conditions often involves the use of electrocardiogram (ECG) and Holter monitor to detect the abnormal heart rhythms. In severe cases, such as ventricular fibrillation, defibrillation may be necessary to restore a normal sinus rhythm.
