This Can Be as Easy as 1-2-3.

Area of Science:

• Cardiology
• Diagnostic Electrocardiography

Background:

• Right ventricular dysfunction and pulmonary hypertension are significant clinical challenges.
• Accurate and early diagnosis is crucial for effective management.

Purpose of the Study:

• To evaluate the specificity of the S1S2S3 electrocardiogram pattern for diagnosing right ventricular dysfunction with pulmonary hypertension.

Main Methods:

• Analysis of 12-lead electrocardiogram (ECG) findings, including the S1S2S3 pattern.
• Assessment of specific ECG criteria: tall R-wave in V1, deep S waves in V5-V6, QRS interval, and right atrial enlargement (P-wave in lead II).

Main Results:

• The S1S2S3 pattern, combined with right-dominant forces on ECG, demonstrates high specificity for right ventricular dysfunction.
• Key indicators include tall R-wave in V1, deep S waves in V5-V6, short QRS duration, and right atrial enlargement.

Conclusions:

• The S1S2S3 pattern is a highly specific electrocardiogram finding for right ventricular dysfunction.
• This ECG signature aids in the diagnosis of pulmonary hypertension and associated right ventricular strain.
