Brugada 1991 four-step algorithm for a regular tachycardia with a wide QRS compl
Brugada 1991 four-step algorithm for a regular tachycardia with a wide QRS complex. Caller assigns absence of an RS complex in all precordial leads, RS interval >100 ms in one precordial lead, AV dissociation, and VT morphology in V1–V2 and V6. Returns diagnosis vt or svt and the stopping step. magent does not interpret ECGs. Not Brugada syndrome, not Vereckei aVR, not RWPT, not Sgarbossa, and not a cardioversion order. Not a medical device.
