Patient Descriptions Of PSVT Episodes
- Patients describe PSVT with sudden palpitations, chest or neck sensations, breathlessness, lightheadedness, or anxiety.
- Episodes commonly last seconds to minutes but can sometimes persist for hours or a full day.
PSVT Is A Non‑Sinus, Supraventricular Rhythm
- PSVT originates above the ventricles and usually does not arise from the sinus node.
- Identifying supraventricular origin narrows diagnostic thinking to atria or AV nodal tissue.
Confirm PSVT With ECG Recording
- Use ECG recordings (12‑lead, event monitor, or wearable) to confirm suspected PSVT.
- Review high‑quality tracings with trained clinicians for accurate diagnosis.
