ECG: Supraventricular Tachycardia
SVT is a narrow complex tachycardia (narrow QRS) with HR of 140-250/min.
Symptoms include pounding chest, chest pain, shortness of breath (SOB), dizziness and loss of consciousness.
One has to recognize this ECG and perform immediate management.
Non-pharmacological maneuver:
- Vagal stimulation ( effective in 25% of cases)
- Valsava maneuver
- Cold water immersion
(google it yourself)
Pharmacological :
- Adenosine 6mg stat. Follow by 12mg after 5min and another 12mg after 5min (effective in 80%)
**The ECG showed that adenosine (effects that last for about 20s) that stuns the AV node (transient blockade) with widening of the QRS complex for a short period of time before the heart rate returns to normal at the rate of 75 beats perminute with the normal atrial sinus taking back the normal activity**
During treatment(pharmacological):
