A 36-year-old man presented to the emergency department with substernal chest tightness of 6 hours’ duration. The chest tightness was initially intermittent but became persistent 1 hour before presentation. He was a current smoker with a smoking history of 10 pack-years. An electrocardiogram (ECG;..

Less than half of patients with a chest pain history indicative of acute coronary syndrome have a diagnostic electrocardiogram (ECG) on initial presentation to the emergency department. The physician must dissect the ECG for elusive, but perilous, characteristics that are often missed by machine analysis. ST depression is interpreted and often suggestive of ischemia; however, when exclusive to leads V1-V3 with concomitant tall R waves and upright T waves, a posterior infarction should first and foremost be suspected...

STUDY OBJECTIVE: Cardiac arrhythmia is a life-threatening condition in older adults who present to the emergency department (ED) with syncope. Previous work suggests the initial ED ECG can predict arrhythmia risk; however, specific ECG predictors have been variably specified. Our objective is to identify specific ECG abnormalities predictive of 30-day serious cardiac arrhythmias in older adults presenting to the ED with syncope. METHODS: We conducted a prospective, observational study at 11 EDs in adults aged 60 years or older who presented with syncope or near syncope...

BACKGROUND: The Romhilt-Estes point score system (RE) is an established ECG criterion for diagnosing left ventricular hypertrophy (LVH). In this study, we assessed for the first time, whether RE and its components are predictive of sudden cardiac arrest (SCA) independent of left ventricular (LV) mass. METHODS: Sudden cardiac arrest (SCA) cases occurring between 2002 and 2014 in a Northwestern US metro region (catchment area approx. 1 million) were compared to geographic controls...

BACKGROUND: ST elevation (STE) on the electrocardiogram (ECG) may be due to acute myocardial infarction (AMI) or other nonischemic pathologies such as left ventricular aneurysm (LVA). The objective of this study was to validate 2 previously derived ECG rules to distinguish AMI from LVA. The first rule states that if the sum of T-wave amplitudes in leads V1 to V4 divided by the sum of QRS amplitudes in leads V1 to V4 is greater than 0.22, then acute ST-segment elevation MI is predicted...

BACKGROUND: Adenosine administration to patients with Wolff-Parkinson-White (WPW) usually increases preexcitation and therefore may be diagnostic for WPW syndrome when the electrocardiogram (ECG) is questionable. We aimed to determine the adenosine response in pediatric patients with WPW pattern on ECG and whether blocked accessory pathway (AP) conduction with adenosine correlated with nonrapid AP conduction measured by invasive electrophysiology study (EPS). METHODS: All patients with WPW ≤ 18 years of age who underwent EPS over a 5-year period were identified...

OBJECTIVE: There is no consensus on the optimal management of recent-onset episodes of atrial fibrillation or flutter. The approach to these conditions is particularly relevant in the current era of emergency department (ED) overcrowding. We sought to examine the effectiveness and safety of the Ottawa Aggressive Protocol to perform rapid cardioversion and discharge patients with these arrhythmias. METHODS: This cohort study enrolled consecutive patient visits to an adult university hospital ED for recent-onset atrial fibrillation or flutter managed with the Ottawa Aggressive Protocol...

VF was observed in four patients (group A) with preexcited AF presenting to the emergency department who had been given 12 mg of adenosine. These patients were resuscitated and underwent electrophysiological study and catheter ablation of the accessory pathway (AP). In a control (group B) of five patients with manifest AP, sustained AF was induced by rapid atrial pacing during electrophysiological study and 12 mg of adenosine was administered. The ECG and electrophysiologic features in the two groups were compared...
