Hyperkalemia Emergencies
Key Points Severe Hyperkalemia Mimics Several Life-Threatening Conditions: Hyperkalemia can produce a wide range of ECG abnormalities that resemble unstable brady and tachy arrhythmias, STEMI, and can also cause pacemaker…
Arrhythmogenic Cardiomyopathy (ACM)
Key Points Definition & Terminology: Arrhythmogenic Cardiomyopathy (ACM), previously known as Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia (ARVC/D), is an inherited disorder characterized by progressive fibrofatty replacement of the ventricular myocardium, predominantly…
LVH vs STEMI: DDx
Key Points LVH Mimicry: Left ventricular hypertrophy (LVH) can mimic anterior coronary occlusion and is a common cause of “false-positive” cath lab activations. Diagnostic Challenge: LVH with strain pattern can…
Early Repolarization vs STEMI: DDx
Key Points Differentiation Challenge: Early repolarization (ER) is a benign ECG pattern often seen in healthy young individuals, characterized by ST segment elevation that can mimic STEMI and acute pericarditis….
Upright T Waves in V1
Key Point Normal T Wave in V1: The normal ECG typically shows a flat or inverted T-wave in lead V1. Upright T-Wave Abnormality: An upright T-wave in V1 (TV1) should…
WPW with Antidromic SVT
Key Points WPW Syndrome: Wolff-Parkinson-White (WPW) syndrome is a condition characterized by ventricular pre-excitation due to a congenital accessory pathway in patients with symptomatic arrhythmias. ECG Recognition: The classic WPW…
WPW with Orthodromic SVT
Key Points WPW syndrome is caused by congenital ventricular pre-excitation via an accessory pathway. The classic sinus rhythm pattern includes a short PR interval, delta wave, and a widened QRS,…
