- Ventricular tachycardia (VT) and supraventricular tachycardia (SVT) have the following differences1234:
- Source: VT originates from the heart's lower chambers (ventricles), while SVT originates from the heart's upper chambers (atria).
- Seriousness: VT is often life-threatening, whereas SVT is rarely serious.
- ECG findings: VT has a wide QRS complex at a rate greater than 100 bpm, while SVT does not.

To view the original source information, use the "Learn more" links.The key difference between VT and SVT is the source of the tachycardia. In VT, tachycardia stems from the heart’s lower chambers, called the ventricles. In SVT, it stems from the heart’s upper chambers, called the atria. Another key difference between the two is that VT is often life threatening, whereas SVT is rarely serious.www.medicalnewstoday.com/articles/v-tach-vs-svtVentricular tachycardia (VT) is more likely in older people with heart disease and can be far more serious. All abnormal heart rhythms are caused by electrical misfires that originate somewhere in the heart. Supra means "above," so in SVT, the errant electrical signals start somewhere above the heart's ventricles (the heart's lower chambers).www.health.harvard.edu/heart-health/different-type…An electrophysiologist or other provider can distinguish between SVT and V-tach by looking at an electrocardiogram (EKG), which measures the heart’s electrical signals. Each has a telltale signature. If your V-tach progresses to ventricular fibrillation, your heart beat can reach 300bpm and you would need medical attention right away.nortonhealthcare.com/news/fast-heart-beat-all-abo…ECG findings for sustained ventricular tachycardia (VT) include wide QRS complex (duration >120 milliseconds) at a rate greater than 100 bpm. Patients may have a normal cardiac output or may be hemodynamically compromised during episodes of VT. Presence or absence of symptoms does not reliably differentiate VT from supraventricular tachycardia.bestpractice.bmj.com/topics/en-us/537 - People also ask
