I was sent the Holter monitor tracing in Figure-1 — but without the benefit of any clinical information. QUESTIONS: A total of 9 QRS complexes are seen in the 2 simultaneously-recorded monitoring leads. How would YOU interpret the rhythm in Figure-1 ? How many P waves do you see? Why do the QRS complexes of beats #4 and 5 in the bottom lead look different than the other 7 beats?

A 50-something man presented in shock with severe chest pain. His prehospital ECG was diagnostic of inferior posterior OMI. The patient was in clinical shock with a lactate of 8. BP was 108 systolic (if a cuff pressure can be trusted) but appeared to be maintaining BP only by very high systemic vascular resistance. He appeared gray in color, with cool skin.

This ECG comes from a 75 yo man who had 2 syncopes in the past few weeks. The 12-lead-EKG at the family doctor showed an inconspicuous finding. Here you can see a section of the patients Holter ECG. There is a very slow junctional escape rhythm. How can this be recognized?

The World Health Organisation (WHO) formally proclaimed COVID-19, the illness spread by a zoonotic SARS-CoV-2, as a pandemic in March 2020, after it had started to spread in late 2019. Even though the pandemic is on the wane, new studies and evidence about it continue to emerge. And, addressing myocardial infarction, recent studies have shown that 1-4% of Athletes untimely die due to myocarditis caused by COVID-19.

I received the following text message with these 3 EKGs (providers text me ECGs all day every day; most are false positives; many are subtle true positives): "Hi Steve, here are 3 EKGs for you (my colleague's case). A 67 yo f developed chest pain this morning." EKG #1 Followed 15 minutes by this #2 EKG: Then the patient received aspirin and Dilaudid (hydromorphone, same effect as morphine) and the pain went away and there was this 3rd ECG: Smith comment: hydromorphone will make any pain go away

This ECG is from an 80-year-old lady who has collapsed or had sycopal episodes several times. The ECG comes from a Holter monitor. She has arterial hypertension and coronary artery disease. The ECG shows a second-degree, Mobitz Type II AV block. In both types of AVB, the PP intervals are usually the same.

Why is this left atrial atypical atrial flutter ( ECG 1 )? Atrial fibrillation can be excluded because nice flutter waves (all look the same) can be clearly identified. With typical right atrial flutter, the reentry circle runs counterclockwise and we see typical saw tooth patterns in the inferior leads (negative flutter waves). The flutter waves are positive in V1 ( ECG 2 ).
