Supraventricular Tachycardia SVT

1. Symptoms

1.1. •heart racing/palpitations

1.2. •dizziness or light-headedness

1.3. •chest pain

1.4. •breathlessness

2. Treatments

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

2.2. If patient is asymptomatic seek expert consultation

2.3. If patient is symptomatic

2.3.1. Try vagal meanuevers

2.3.2. Carotid massage

2.3.3. Cardioversion 0.5 Joules/Kg

2.3.4. Adenosine 6mg, 12mg, 12mg

2.3.5. Transport for expert consultation

3. Algorithm

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

5. 3 Types

5.1. •Atrioventricular nodal reentrant tachycardia (AVNRT)

5.2. •Atrioventricular reciprocating tachycardia (AVRT)

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

6. Supraventricular Tachycardia EKG Strip

6.1. Rhythm: Regular

6.2. Rate: Fast (150-250 bpm)

6.3. P Wave: Merged with T wave

6.4. PR Interval: Normal (0.12 sec)
