What is the difference between “narrow complex” and “wide complex” tachycardia?
We’re speaking honestly here? Well honestly, I think there’s a reason why God invented cardiologists. Narrow or wide complex, my concern is: are they making a blood pressure? If they are call for help and monitor closely. If they’re not, call for help and start a code. This is not to say that narrow versus wide doesn’t exist, or matter they do, and it does, and you will see this kind of thing. But the practical principle for you as the person at the bedside is always the same is the patient perfusing with this rhythm? Get all the help you need. I guess I should say that my own interpretation is that wider complexes tend to be coming from lower down, and therefore are probably VTs and that narrower complexes are probably coming from higher up, and may be things like SVTs supraventricular tachycardias. Compare the VF strip to the PAT strip, and you’ll clearly see the difference.
