Pearls in Syncope ECG Interpretation

Pearls in Syncope ECG Interpretation
Abnormal Ecg Findings of Cardiac Syncope

In the ED patient with syncope, the ECG should be scrutinized for signs of ischemia, bradydysrhythmias, tachydysrhythmias, and conduction delays. Critical diagnoses to consider that can be detected with the ECG include: Brugada syndrome, Long or short QT syndromes ...

Shortness of Breath (Dyspnea) – Differential Diagnosis, Examination and Investigations

Shortness of Breath (Dyspnea) – Differential Diagnosis, Examination and Investigations
The Causes of Shortness of Breath (Dyspnea)

Shortness of breath (dyspnea) is the subjective sensation of breathlessness which is excessive for any given level of activity. It is important to remember that any component of the respiratory system can cause dyspnea.

Beyond Diuresis – Treatment Adjuncts in Cardiogenic Pulmonary Edema

Beyond Diuresis – Treatment Adjuncts in Cardiogenic Pulmonary Edema
The emergency management of patients with cardiogenic shock, acute pulmonary edema, or both

Diuretics may not be the preferred initial therapy, however, for those patients with vascular failure, who are often euvolemic, or those with cardiogenic shock, who are often hypovolemic. In these patients, the emergency provider should first optimize preload and afterload reduction with the use of noninvasive positive pressure ventilation (NPPV), nitrates, or inotropes as indicated.

Palpitations – Differential Diagnosis, Examination and Investigations

Palpitations – Differential Diagnosis, Examination and Investigations
Algorithm for the investigation of the patient with palpitations
  • Post category:Cardiology

Always check what the patient means by "palpitations" or clarify what you mean, as the word means different things to different people. It is usually understood as an awareness of the heartbeat. The most common cause is an arrhythmia, although other causes include conditions causing an increase in stroke volume (e.g., regurgitant valvular disease) or conditions causing an increase in cardiac output, often noncardiac causes (e.g., exercise, thyrotoxicosis, anemia, or anxiety).

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.

Don’t Stress the Stress Test in Suspected ACS
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.
