PEARL # 2: When the rate of AFib is rapid — this irregular tachycardia may look regular when it is not. That the rhythm is AFib — is easier to appreciate in Figure-3. Clearly, the rhythm is AFib — here with a controlled ventricular response. ECG Blog #240 — reviews my approach to the ECG assessment of regular SVT rhythms.

NOTE: For more on ECG recognition of RVH and/or pulmonary hypertension ( re the qR pattern in lead V1 ) — See ECG Blog #234 and Blog #248. Because of this, it is uncommon to see sinus tachycardia with a prolonged PR interval. Unfortunately — my search for 2:1 atrial activity ( as shown in Figure-3 ) was unsuccessful.

The ECG and long lead II rhythm strip in Figure-1 — was obtained from a COVID positive patient with persistent tachycardia not responding to Diltiazem. Figure-1: The initial ECG — obtained from a patient with persistent tachycardia. ( ECG Blog #185 — Review of the P s, Q s, 3 R Approach for systematic rhythm interpretation.

The finding of a fairly regular, wide tachycardia without clear sign of atrial activity ( especially when seen in an acutely symptomatic patient ) — should immediately prompt a diagnosis of VT until proven otherwise. These findings suggest that instead of VT — the rhythm in Figure-1 is AFib with a fairly rapid ventricular response.

By the P s , Q s , 3 R Approach ( See ECG Blog #185 ): The rhythm in Figure-1 is clearly not R egular. PEARL #2: As cited in ECG Blog #252 — my favorite truism in arrhythmia interpretation is, "The commonest cause of a pause is a blocked PAC".

male with pertinent past medical history including Atrial fibrillation, atrial flutter, cardiomyopathy, Pulmonary Embolism, and hypertension presented to the Emergency Department via ambulance for respiratory distress and tachycardia. Description : Regular Wide Complex Tachycardia at a rate of about 160. SVT with aberrancy?

There were times when it would be usurped by sinus tachycardia, then return to this rhythm. This does NOT seem irregularly irregular enough for AFib … Instead — there is almost “group beating” with “Wenckebach periodicity”. CT of chest showed the bullet path through his right lung but nowhere near his heart. There is a wide complex.
