Dysrhythmias V: Evaluating Dysrhythmias

Dysrhythmias V: Evaluating Dysrhythmias

Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Radiology
Obstetrics & Gynecology
Emergency Medicine

Background:

Ectopic pregnancy occurs when a fertilized egg implants outside the uterus.
Abdominal pain and vaginal bleeding are key symptoms prompting emergency department evaluation.
Accurate diagnosis is essential for timely management and preventing severe complications.

Purpose of the Study:

To illustrate the sonographic findings of ectopic pregnancy.
To review ultrasound differentials that mimic ectopic pregnancy.
To emphasize the importance of early detection for improved clinical outcomes.

Main Methods:

Pictorial essay format.
Description and illustration of sonographic findings.
Review of differential diagnoses on ultrasound.

Main Results:

Ectopic pregnancy diagnosis relies on laboratory values and ultrasound.
Ultrasound findings for normal and ectopic pregnancies can be subtle and challenging.
Differential diagnoses can mimic ectopic pregnancy on ultrasound.

Conclusions:

Early detection of ectopic pregnancy via ultrasound is critical.
Prompt treatment, including medical management, improves patient outcomes.
Radiologists play a key role in diagnosing ectopic pregnancy and its mimics.
