Dysrhythmia in LVADs
Key Points Ventricular Fibrillation in LVADs: Ventricular fibrillation (VF) in patients with Left Ventricular Assist Devices (LVADs) can be rapidly fatal but is often better tolerated initially due to the…
Terminal QRS Distortion (OMI Pattern)
Key Points Early Repolarization (ER): A common ECG finding that can produce widespread ST-segment elevation, often mimicking STEMI or acute pericarditis. ST Segment Morphology: Convex and horizontal ST-segment morphology is…
Electrical Storm
Key Points Definition: Electrical storm is defined as three or more episodes of sustained ventricular tachycardia (VT), ventricular fibrillation (VF), or appropriate shocks from an implantable cardioverter-defibrillator (ICD) within 24…
STAT ECGs: The Life Savers
Key Points About Life Saving ECGs: Definition: STAT ECGs refer to emergent electrocardiograms that are critical for the immediate diagnosis and management of a variety of life-threatening conditions. Purpose: The…
Ventricular Flutter
Key Points Definition: Ventricular flutter is a rapidly fatal cardiac arrest rhythm, closely related to ventricular fibrillation, requiring immediate defibrillation and high-quality CPR. Characteristics: It is marked by regular, continuous…
Bidirectional Ventricular Tachycardia
Key Points Definition: Bidirectional Ventricular Tachycardia (VT) is a rare and unique form of VT characterized by QRS complexes that alternate in axis and morphology from beat to beat. This…
Severe Hypothermia
Key Points Hypothermia and ECG: Severe hypothermia causes distinct ECG changes that can be life-saving if recognized early. These changes reflect the slowing of the heart’s electrical activity as body…
Slow Ventricular Tachycardia (VT)
Key Points Definition: Slow ventricular tachycardia (VT) is characterized by a ventricular rate of 100-120 bpm. Distinction: Regular VT typically has a ventricular rate > 120 bpm. Context: Slow VT…
