1. Supraventricular tachycardia (SVT) is a cardiac arrhythmia characterized by very rapid or erratic beating. SVT is also called paroxysmal supraventricular tachycardia (PSVT)

2. 3 Types

2.1. •Atrioventricular nodal reentrant tachycardia (AVNRT)

2.2. •Atrioventricular reciprocating tachycardia (AVRT)

2.3. •Wolff-Parkinson-White syndrome (a type of AVRT)

3. Symptoms

3.1. •heart racing/palpitations

3.2. •dizziness or light-headedness

3.3. •chest pain

3.4. •breathlessness

4. Supraventricular Tachycardia EKG Strip

4.1. Rhythm: Regular

4.2. Rate: Fast (150-250 bpm)

4.3. P Wave: Merged with T wave

4.4. PR Interval: Normal (0.12 sec)

4.5. QRS: Normal (.10 sec)

4.6. Notes: PR interval can be difficult to measure

5. Treatments

5.1. Certain maneuvers, medications, an electrical shock to the heart (cardioversion), and catheter-based procedures (ablation) can help slow the heart

5.2. If patient is asymptomatic seek expert consultation

5.3. If patient is symptomatic

5.3.1. Try vagal meanuevers

5.3.2. Carotid massage

5.3.3. Cardioversion 0.5 Joules/Kg
