Academic AFIB Arrhythmia

M y I MPRESSION : The rhythm in Figure -1 is almost certain to be very rapid AFib in a patient with WPW. NOTE #2: Surprisingly, it is not uncommon for patients in AFib with WPW to be hemodynamically stable — despite having exceedingly rapid ventricular rates. The resultant rhythm after cardioversion is shown in Figure-2.

In the interest of academic discussion Ill present a nother p erspective on selected aspects this case. C linical P oints R egarding E CG # 1 : We are told that the patient is a middle-aged woman and that she previously had been in AFib with LBBB. Atrial activity could easily be lost within all the baseline undulations that we see.

That said — rhythm interpretation here is more of an academic interest — as the most striking findings are the widespread T-wave inversions and QT prolongation. Learning points : Takotsubo can lead to cardiac arrest from ventricular arrhythmia. The patient was diagnosed with stress cardiomyopathy.

Failure to follow this advice will undoubtedly lead to overlooking subtle acute MIs — and , it will especially lead to misdiagnosing many cardiac arrhythmias ( as was done in this case ). How can you avoid overlooking this arrhythmia? The reasons for overlooking this arrhythmia are simple: True MAT is not a common rhythm.

During hospital admission she had a variety of atrial arrhythmias, which eventually resolved, likely due to her decreasing flecainide level. For example: Statistical likelihood that the regular WCT in ECG #1 might be AFlutter ( instead of VT ) is greatly increased in a patient with AFib who is taking Flecainide.

In some cases the ischemia can be seen "through" the flutter waves, whereas in other cases the arrhythmia must be terminated before the ischemia can be clearly distinguished. Learning Points: Acute arrhythmias such as SVT, rapid AF, and atrial flutter may coexist and/or be caused by ischemia, or vice versa.

Determination of the cardiac rhythm in today's case is of more than academic interest — since my initial "quick glance" of ECGs from this woman in her 60s who presented in shock — was that the QRS looked wide with an irregular rhythm that might represent a polymorphic VT.
