[link] == MY Comment , by K EN G RAUER, MD ( 8/5 /2024 ): == As one who has been fascinated by cardiac arrhythmias for decades — I find the most difficult aspect of rhythm interpretation for me, is distinguishing between what is "real" vs what is artifact, or simply background "noise". We learn best when we learn from each other.

Whatever the specific etiology of today's arrhythmia is, the “good news” is — that this rhythm will most probably improve with reperfusion of the "culprit" artery. That said — I found today's arrhythmia fascinating, and worthy of more in-depth analysis. Using calipers facilitates the process.

This familial cardiac arrhythmia is the result of gene mutation. These patients are at high risk for malignant arrhythmias. Typically — these arrhythmias are induced by exercise or intense emotional states ( ie, associated with increased catecholamine discharge ). The heart is structurally normal in patients with CPVT.

Realizing that slight variation in the P-P interval is common ( known as sinus arrhythmia ) — the PINK arrows in Figure-3 suggest the probable location of underlying sinus P waves. Certain complex arrhythmias may have more than a single plausible rhythm interpretation. This is precisely what we see in Figure-4.

KEY Point: When most beats in an arrhythmia are regular, but some are not — the best CLUE to interpretation often resides in looking for a “ break ” in the rhythm ( such as is seen between beats #13 and 14 in Figure-2 ). The simple step of labeling all of the obvious P waves — is surprisingly helpful in evaluating the rhythm.

What is unusual about this arrhythmia? Doing so suggests that the R-R interval of this exceedingly rapid arrhythmia is just a tiny amount over 1 large box — which corresponds to a ventricular rate just under 300/minute ( ie, between 290-300/minute ). How would YOU interpret the ECG in Figure-1 ?

Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. In light of the risk of arrhythmia events observed in the Mizusawa trial, a formal EP study might be reasonable to obtain in those with fever induced asymptomatic Brugada ECG changes to help risk stratify these patients.
