Aggresive Nitroglycerin Usage in Acute Decompensated Heart Failure (ADHF)
Phenotypes of Acute Decompensated Heart Failure (ADHF), their Presentations, and Suggested Therapy

In recent years, there are increasing data that support the use of high-dose vasodilator therapy as the initial treatment for patients with acute decompensated heart failure (ADHF)

Know the Differential for ST Segment Elevation: It’s More Than Just ACS

Know the Differential for ST Segment Elevation: It’s More Than Just ACS
ST Segment Elevation - Differential Diagnosis

There are numerous conditions that cause ST-segment elevation (STE) on an ECG that are not attributable to an acute coronary syndrome. In order to avoid errors in diagnosis or management, it is important for the EP to know the differential diagnosis for STE.

Pitfalls in Hypertensive Emergencies

Pitfalls in Hypertensive Emergencies
Drugs for hypertensive emergencies and urgencies

Approximately 1% to 2% of patients with hypertension will present with a hypertensive emergency, defined as organ dysfunction due to an elevated blood pressure. Importantly, there is no specific blood pressure threshold that identifies a patient with a hypertensive emergency.

Algorithm for choosing the appropriate candidate for stress testing in patients with suspected coronary artery disease (CAD)
  • Post category:Cardiology

The goal of a cardiac stress test is to identify the patient with obstructive coronary artery disease (CAD), typically defined as stenosis of 50% or more of a coronary artery on angiography.

Beware of the “Highly Sensitive” Troponin

  • Post category:Cardiology

In 2009, “highly sensitive” troponin assays became available. These assays can detect the presence of troponin at much lower serum levels compared to traditional troponin assays. “Highly sensitive” troponins have a higher sensitivity and negative predictive value, but lower specificity, when compared with traditional troponin assays.

The differential diagnosis of Wide Complex Tachycardia

Ventricular tachycardia is a wide complex tachycardia (WCT) that is typically associated with coronary artery disease or other significant heart disease. The rapid rate, often in conjunction with poor baseline…

Criteria for Discriminating Ventricular Tachycardia from SVT with Aberration

It can be especially difficult to distinguish between ventricular tachycardia (VT) and supraventricular tachycardia (SVT) with aberrant conduction. Fortunately, if the patient is unstable, the initial treatment for both rhythms is synchronized electrical cardioversion.
