So it must be atrial fibrillation. Then I always look to see if the initial deflection of the QRS has a lot of voltage change per change in time (seen in tachycardias that are initiated from above the ventricle because the propagate through fast conducting purkinje fiber. Pacemaker mediated tachycardia!

Background The value of empirical superior vena cava isolation (SVCI) following pulmonary vein isolation (PVI) to improve the efficacy of radiofrequency catheter ablation (RFCA) for paroxysmal atrial fibrillation (PAF) remains controversial. RFCA was guided by quantitative AI in both groups.

Whenever it is this fast, you need to be very careful to ascertain whether it is irregular ( as in atrial fibrillation with rapid ventricular respsonse ) or regular ( as in VT ). This is not because it is polymorphic VT; it is because it is WPW with atrial fibrillation. Smith : What do you think? It is not VT; it is AF.

Methods This was a case–control study of women admitted in labour to one of eight hospitals of Northwell Health from January 2015 to June 2021. Objectives Examine the association between arrhythmias and adverse maternal outcomes in women with structurally normal hearts. Arrhythmia was previously diagnosed in 58.0% AF and 8.1%

ACUTE MI (I allowed Acute MI to be in the report because I knew there would be an elevated troponin from ischemia, which is the definition of acute MI -- but in this case it would most likely be a Type 2 MI from tachycardia) There is also LA-RA lead reversal.

In the study, information from large national registers was cross-checked.
