Rate for SVT?

Explanation:
Supraventricular tachycardia is a rapid, regular narrow‑complex rhythm. In adults, 150 beats per minute or higher is the practical lower cutoff used to classify a tachycardia as SVT on telemetry. This threshold helps distinguish SVT from sinus tachycardia, which, even when fast, typically does not sustain rates at or above 150 bpm at rest. While SVT can exceed 150 and reach much higher rates, using 150 as the cutoff ensures you identify most SVT episodes promptly; waiting for a higher threshold like 180 bpm would miss cases that begin around 150–170 bpm. Rates around 100–120 bpm are more consistent with sinus tachycardia or other slower tachyarrhythmias, not classic SVT.
