PR Segment Elevation
“PASTOR” is used to remember the key features of acute pericarditis and aid in diagnosis and management. It stands for Pleuritic chest pain, Auscultatory pericardial friction rub, ST-segment elevation on ECG (and/or PR depression), Temperature elevation (fever), Other associated symptoms (like dyspnea, cough, etc.), and Recent viral illness or other underlying causes.
Here’s a breakdown of the mnemonic:
- Pleuritic chest pain: Pain that worsens with breathing and lying down, and is relieved by sitting up and leaning forward.
- Auscultatory pericardial friction rub: A characteristic scratching, squeaking, or crunching sound heard with a stethoscope, indicating inflammation of the pericardium.
- ST-segment elevation on ECG (and/or PR depression): The electrocardiogram may show widespread ST-segment elevation (and PR depression), which is a common finding in acute pericarditis.
- Temperature elevation (fever): Fever is a common systemic sign of inflammation.
- Other associated symptoms: Pericarditis can be accompanied by other symptoms like dyspnea, cough, fatigue, and myalgias.
- Recent viral illness or other underlying causes: Many cases of pericarditis are triggered by viral infections, but other causes include bacterial infections, autoimmune diseases, and trauma.
