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 ).

Here is a normal LBBB: In LBBB, monophasic wide R-waves should be limited to the lateral leads in left bundle branch block, as in this ECG. In that ECG above, there are monophasic R-waves starting in lead V2 all the way out to V6. But why does this EKG look nothing like left bundle branch block? Is this sinus tachycardia or VT?

A man in his 90s with a history of HTN, CKD, COPD, and OSA presented to the emergency department after being found unresponsive at home. EKG on arrival to the ED is shown below: What do you think? ng/mL (consistent with prior baseline), and a repeat EKG was obtained 1 hour after the initial EKG. or basilar ischemia.

This is the result for this ECG, from MDcalc.com : The most accurate cutpoint is 18.2. Here is a similar case from Pendell: This ECG was handed over at triage. That said — the ST-T wave in lead V2 looks to be small only if viewed in the context of its absolute height, as one of 12 leads in the initial ECG shown above in today's post.

Written by Magnus Nossen, with some edits by Smith This ECG was transmitted electronically by EMS for evaluation. How would you interpret the ST changes seen in this ECG? Will you accept this patient for emergent coronary angiogram based on the ECG changes? Does the ECG represent STEMI-negative OMI findings?

The following ECG was recorded. The presenting ECG shows SR with narrow QRS complexes. First troponin I returned 3174 ng/l, at which point a repeat ECG was ordered. Not much difference from 1st ECG. At this point an old ECG on file was found for comparison. Upon admission she had ongoing slight chest discomfort.
