What is the heart rate of an SVT?

In the context of a supraventricular tachycardia (SVT) event, the heart rate typically exceeds 150 beats per minute. SVT is characterized by an abnormally fast heart rhythm that originates at or above the atria. This rapid heart rate can result from various mechanisms, such as re-entry pathways or increased automaticity in the atrial tissue.

Given that SVT significantly accelerates the heart rate, it is commonly recognized that patients may present with heart rates typically starting around 150 beats per minute and often reaching even higher levels, thus fitting the criterion of being categorized as "over 150." This understanding is crucial for monitor technicians, as identifying the heart rate associated with SVT helps in the assessment and management of patients experiencing this arrhythmia.
