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.

Measurement of QT interval is very important, as QT prolongation can predispose to serious, life threatening ventricular arrhythmias. QT prolongation leads to torsades des pointes, which is a very serious arrhythmia. PR segment elevation and depression can occur in atrial infarction and pericarditis. to 0.43, normal range.

Pericarditis? If you were thinking that this is pericarditis, that would be possible in the absence of any clinical information. However, there is zero PR depression which would be VERY unusual in pericarditis. P.S.: Acute pericarditis may produce diffuse ST elevation. Presence of STD is helpful; absence is not.

Freedom from atrial arrhythmia was evaluated continuously through 12 months using standard rhythm monitoring for symptomatic episodes and 24-hour Holter at 6 and 12 months.RESULTS:Eighty-two patients (74% male, 51.2% paroxysmal, and 58.5% deep sedation) were treated.

This is the proposed mechanism of precipitation of arrhythmias in Brugada syndrome during febrile episodes. There is a potential risk for drug challenge in that life threatening ventricular arrhythmias could be precipitated. This leads to shortening of action potential duration. With proper precautions, risk can be reduced.

The rhythm is uncertain ( ie, We only see 4 beats — because the same 4 beats are repeated in limb and chest leads — but in lead II there appears to be sinus bradycardia and arrhythmia plus a P wave with a PR interval too short to conduct preceding beat #1 — therefore need for a longer period of monitoring ).

The "flu-like" illness suggests myo- or pericarditis, but that would be a diagnosis of exclusion. Jenkins and Frick — I offer 3 additional examples of artifactual distortion ( excerpted from my ECG Blog ) — that resulted in arrhythmia misdiagnosis.
