The ECG in Figure-1 — was obtained from an older man who had just completed dialysis — and , is now complaining of abdominal discomfort that radiates to his chest. Figure-1: The initial ECG in today's case. ( To improve visualization — I've digitized the original ECG using PMcardio ). How would YOU approach this case?

What if you were asked to interpret the ECG in Figure-1 ? Figure-1: The initial ECG in today's case. ( To improve visualization — I've digitized the original ECG using PMcardio ). By the P s, Q s, 3 R Approach ( which I review in ECG Blog #185 ): Lots of P waves are present — being well seen in the long lead II rhythm strip.

Figure-1: Multi-lead rhythm strip obtained from telemetry monitoring. MY Thoughts on the Rhythm Strip in Figure-1: The first 4 beats in this 11-beat rhythm strip are sinus — as determined by the presence of regular upright P waves , with a constant PR interval in lead II ( RED arrows in Figure-2 ).

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. ( To improve visualization — I've digitized the original ECG using PMcardio ).

There were 2 prehospital ECGs: What do you think? There is reciprocal STD in inferior leads. There is a rather large R-wave in lead V1 and a very large R-wave in V2, suggesting an atypical RBBB. There is a rather large R-wave in lead V1 and a very large R-wave in V2, suggesting an atypical RBBB. There is STE in aVR.

This ECG was recorded: What do you think? Another ECG was recorded: What do you think? Because there is an ST depression vector towards leads V5 and II, leads aVF and II cannot manifest ST elevation or hyperacute T-wave from the inferior OMI. There is widespread ST depression. That this is all demand ischemia is unlikely.

HbS has reduced solubility in the setting of hypoxia, leading to sickling of the RBCs. Sickling leads to vascular occlusion, end-organ ischemia, and decreased RBC lifespan, which, in turn, leads to pain crisis, acute anemia, sequestration, infection, and acute chest syndrome (ACS). ECG: Evaluate for ischemia, right heart strain.
