U Wave Basics
Key Points Definition: U waves are small, rounded waves that follow the T wave on the ECG, most commonly seen in the precordial leads (V2-V3). They are less frequently discussed…
STAT ECG Diagnoses: the significance of inverted U waves
A 58-year-old man presents to the emergency department with acute onset chest pain and diaphoresis. The following ECG is obtained on arrival:
Reverse Wellens Waves: not all biphasic T waves are indicative of ACS!
A 25-year-old woman presents to the emergency department with lightheadedness and palpitations for 1 week. Her symptoms worsened today with a near-syncopal episode. She is thin/frail and dehydrated in appearance….
Differential Diagnoses: a triad of long QT interval, PVCs, & ST segment depression
A 56-year-old woman presents to a busy ED dehydrated with acute gastroenteritis. She is placed in a hallway bed and treated with IV fluids and ondansetron. On reassessment the patient…
