Practical Manual of Echocardiography in the Urgent Setting

Practical Manual of Echocardiography in the Urgent Setting

In the acute care setting, medicine happens at full speed and with little margin for error. As echocardiography plays an ever more important role in the diagnosis of patients who present with symptoms that suggest a cardiovascular emergency, clinicians must learn to collect, process and act on echocardiographic information as quickly and effectively as possible.

Practical Manual of Echocardiography in the Urgent Setting covers the essentials of echocardiography in the acute setting, from ultrasound basics to descriptions of all pertinent echocardiographic views to clear, stepwise advice on basic calculations and normal/abnormal ranges.

This compact new reference:

• Provides step-by-step guidance to acquiring the correct views and making the necessary calculations to accurately diagnose cardiac conditions commonly encountered in urgent settings.
• Presents information organized by complaint/initial presentation so that readers can work from this first knowledge of the patient through the steps required to pinpoint a diagnosis.
• Covers echo basics, from sound wave characteristics/properties to common device settings to basic ultrasound formulas
• Includes diagnostic algorithms fitted to address the differential diagnosis in the most commonlyencountered clinical scenarios.

Designed and written by frontline clinicians with extensive experience treating patients, Practical Manual of Echocardiography in the Urgent Setting is the perfect pocket-sized guide for residents in cardiology, emergency medicine, and hospital medicine; trainees in echocardiography; medical students on cardiology or emergency medicine rotations; technicians, nurses, attending physicians?anyone who practices in the urgent setting and who needs reliable guidance on echocardiographic views, data and normal/abnormal ranges to aid rapid diagnosis and decision-making at the point of care.
