narrow & irregular tachycardia
Results:
Narrow & Irregular Tachycardia DDx
Key Points Narrow irregular tachycardia = QRS <120 ms with variable R–R interval. The big three DDx: Atrial fibrillation (AF) with RVR, atrial flutter with variable block, multifocal atrial tachycardia…
How to avoid misdiagnosis of irregular rhythms
A 80-year-old woman is referred to the emergency department for suspected rapid atrial fibrillation. The following ECG is obtained on arrival:
EMS ECGs: regular and irregular narrow complex tachycardias, junctional rhythms, the ECG in LVAD patients, and more!
A 62-year-old man is found unresponsive at home. The following EMS ECG is obtained:
EMS ECGs: what isoelectric baseline should be used to measure ST segment deviation, arrhythmias, hypotension in patients with MI, and more!
A 54-year-old man presents to the emergency department by EMS with ischemic chest pain and is found to be hypotensive. The following ECG is obtained:
