Lead Placement
Results:
The Lewis Lead (Unmasking Atrial Activity)
Key Points: Purpose: The Lewis lead (modified S5 lead) is a modified ECG lead configuration designed to amplify atrial electrical activity, making P waves, flutter waves, and the relationship between…
The Bix Rule (Unmasking Atrial Flutter)
Key Points: Definition: The Bix rule is a bedside ECG clue suggesting that there may be twice as much atrial activity as is initially apparent. If an atrial deflection falls…
ECG Foundations: Vectors, Leads, & Activation
Key Points: An ECG records voltage differences over time. The ECG tracing is a plot where the horizontal axis is time and the vertical axis is voltage. Leads are viewpoints….
Proper ECG Electrode Placement
Key Points A diagnostic 12‑lead ECG is only as good as your electrode placement. Misplacement can mimic MI, BBB, or poor R‑wave progression and trigger unnecessary workups. A standard 12‑lead…
Dextrocardia
Key Points Dextrocardia is a congenital condition where the heart is located on the right side of the thorax. Situs inversus totalis refers to complete reversal of all thoracic and…
