Can You Be Certain?
You are asked for your opinion on this electrocardiogram (ECG). No history is available. Can you be certain of your diagnosis?

The History Matters!
How would you interpret today’s 12-lead electrocardiogram and long lead V1 rhythm strip if the history was that of an older adult with known coronary disease? Would your interpretation change if, instead, the patient was a younger adult with a known history of severe congenital heart disease, having been operated on a number of times as a child?

Psychiatric Medications and Long QT Syndrome: A Safe Combination?
A retrospective study of patients with electrocardiogram long QT interval syndrome and psychiatric disease suggests that with proper pharmacologic treatment and counseling, the patients can be treated safely with psychiatric drugs known to increase the QT interval.

Wellens’ Syndrome or Not?
Today’s patient is a middle-aged man who presented to the emergency department (ED) with a history of chest pain with exertion during the past two weeks. His chest pain had been increasing and was at its most severe level the day he presented to the ED. The initial serum troponin level in the ED was more than 10,000 ng/L. Does the clinical scenario suggest Wellens’ syndrome?

What Are Hyperacute T-Waves and What Do They Mean?
A retrospective study of emergency department patients suspected of having an acute coronary syndrome has shown that a computer system for determining a new quantitative high-amplitude electrocardiogram (ECG) T-wave score has a high specificity and reasonable sensitivity for identifying patients with acute coronary occlusion that performs as well as ECG ST-elevation myocardial infarction criteria.

Acute STEMI or Something Else?
Interpret the electrocardiogram (ECG) in the figure without the benefit of any clinical information. Is this ECG indicative of an acute anterior ST-elevation myocardial infarction?

Artificial Intelligence ECG Analysis to Rule Out Acute Myocardial Infarction
A large Korean study of an artificial intelligence electrocardiogram (ECG) interpretation algorithm for identifying patients with acute myocardial infarction showed a high degree of accuracy for diagnosing acute myocardial infarction and identifying patients at risk for 30-day major adverse cardiac events in an emergency department setting, which was similar or superior to standard risk stratification methods.

What Kind of Block?
The electrocardiogram in the figure was obtained from an older adult who presented for evaluation of syncope. What kind of atrioventricular (AV) block is present? Or is the rhythm something other than an AV block?
-
The Cause of the ‘Burning?’
The electrocardiogram (ECG) in the figure is from a man with a new and severe “burning” chest discomfort. On seeing this ECG, the paramedic team requested activating the cath lab. Would you have done the same?

Ten-Year Outcomes of the SCOT-HEART Study
The 10-year follow-up of the SCOT-HEART Study of new-onset chest pain patients randomized to standard care vs. the addition of coronary computed tomography angiography (CTA) has shown that coronary heart disease-related death, myocardial infarction, and other adverse cardiovascular outcomes are reduced with CTA use, perhaps because preventive therapy is increased.
