Paroxysmal Supraventricular Tachycardia
PSVT
PSVT is a type of abnormal heart rhythm where the heart suddenly beats much faster than normal due to electrical signals starting in the atria or the atrioventricular (AV) node. Episodes begin and end abruptly, often lasting seconds to hours, and may cause palpitations, dizziness, chest discomfort, or shortness of breath. It is usually not life-threatening but can be distressing and disruptive. Common triggers include stress, caffeine, alcohol, or certain medications, and treatment may involve vagal maneuvers, medications, or catheter ablation in recurrent cases.

# Treatment Summary for Paroxysmal Supraventricular Tachycardia Adenosine is the first-line IV treatment for PSVT, given as a rapid push to reset heart rhythm, with higher doses used if needed. Vagal maneuvers offer a non-invasive option patients can attempt at home to slow their heart rhythm. For medication alternatives, Diltiazem and Metoprolol IV both slow AV node conduction and restore normal rhythm, with selection based on patient factors and prior medication use. Synchronized cardioversion is reserved for unstable patients or those unresponsive to medication, delivering a timed electrical shock for rapid rhythm restoration.
