Interpreting ECG Findings in Acute Pericarditis
In cases of acute pericarditis, accurate interpretation of ECG findings is vital for effective diagnosis and management. By recognizing the specific ECG changes associated with pericarditis, clinicians can make informed decisions and provide appropriate treatment. Let’s delve into the ECG patterns observed in acute pericarditis and explore how to interpret these findings with precision.
ECG Changes in Acute Pericarditis
When analyzing an ECG in a patient with acute pericarditis, certain characteristic changes can be observed. These changes primarily involve the ST segment and T wave. Here are the key ECG findings in acute pericarditis:
- Diffuse ST Segment Elevation: One of the hallmark ECG changes in acute pericarditis is diffuse ST segment elevation across multiple leads. This elevation typically extends concavely upward, often creating a shape resembling a “saddle”.
- PR Segment Depression: Alongside the ST segment elevation, a characteristic finding in acute pericarditis is PR segment depression, also known as PR scooping. This depression is commonly observed in leads II, III, and aVF.
- Reciprocal ST Segment Changes: It’s crucial to note that while the ST segment is elevated in the leads directly overlying the affected pericardium, reciprocal ST segment changes may be present in the leads opposite to those with elevation. These reciprocal changes often manifest as ST segment depression.
- T Wave Inversions: Another ECG finding that may be present in acute pericarditis is T wave inversions. These inversions typically occur in the same leads as the ST segment elevation, maintaining a concave shape that mirrors the ST segment changes.
Interpreting the ECG Findings
While the presence of these ECG changes suggests acute pericarditis, it’s essential to consider the clinical context and other diagnostic criteria for a comprehensive assessment. Generally, a combination of ST segment elevation, PR segment depression, and the absence of significant Q waves supports the diagnosis of acute pericarditis.
However, it’s essential to differentiate acute pericarditis from other conditions that may present with similar ECG changes, such as myocardial infarction or early repolarization. Close attention to the temporal relationship of symptoms, absence of troponin elevation, and additional ECG features can aid in accurate interpretation. A thorough evaluation by an experienced healthcare professional is crucial for an accurate diagnosis. Acute Pericarditis ECG Patterns & Diagnosis Tips

Key Criteria for Acute Pericarditis ECG Diagnosis
In diagnosing acute pericarditis based on ECG findings, several key criteria are considered. These criteria help identify the characteristic patterns that suggest the presence of pericardial inflammation. Here are the essential criteria to consider:
- PR Segment Depression: In acute pericarditis, the PR segment is commonly depressed compared to the baseline. This depression is typically seen in multiple leads.
- ST Segment Elevation: One of the hallmarks of acute pericarditis is widespread ST segment elevation, often concave in shape. This elevation is observed in various leads and is not confined to a specific territory.
- PR Segment Elevation: Along with ST segment elevation, PR segment elevation may be present in some cases. This finding is more commonly seen in leads with PR segment depression.
- T Wave Inversions: T wave inversions can occur in acute pericarditis, often in a diffused manner and opposite to the QRS complex polarity.
- Normal QRS Complex: The QRS complex tends to remain normal in acute pericarditis, without significant changes in duration or morphology.
These criteria, in combination with clinical symptoms and medical history, play a vital role in the accurate diagnosis of acute pericarditis. It is important to note that while these criteria are helpful, they may not be present in all cases. The interpretation of ECG findings should consider the overall clinical context and the presence of other supporting evidence.
- Criteria Description
- PR Segment Depression PR segment is commonly depressed compared to the baseline.
- ST Segment Elevation Widespread ST segment elevation, often concave in shape.
- PR Segment Elevation PR segment elevation may be present in some cases.
- T Wave Inversions T wave inversions in a diffuse pattern, opposite to the QRS complex polarity. Normal QRS Complex QRS complex remains normal without significant changes.
Common ECG Patterns in Acute Pericarditis
When diagnosing acute pericarditis, understanding the characteristic ECG patterns is vital. These patterns can help differentiate acute pericarditis from other cardiac conditions based on ECG findings. In this section, we will explore the most common ECG patterns observed in acute pericarditis, providing you with valuable insights that will enhance your diagnostic skills.
Note: It is important to interpret ECG findings in the context of the patient’s clinical presentation and history to ensure an accurate diagnosis.
Elevated ST Segments
One of the hallmark ECG findings in acute pericarditis is the presence of diffuse ST segment elevations, typically seen in all leads except aVR and V1. These elevations are often concave and can extend into the T wave, creating a characteristic PR depression. This global ST segment elevation is a key feature in identifying acute pericarditis.
PR Segment Depression
In addition to elevated ST segments, acute pericarditis may also present with PR segment depression in multiple leads. This PR segment depression can be observed in leads II, III, aVF, V4-V6, and is another important ECG pattern to consider when diagnosing acute pericarditis.
Reciprocal ST Segment Changes
An interesting ECG finding in acute pericarditis is the presence of reciprocal ST segment changes. While the diffuse ST segment elevations occur in most leads, the corresponding reciprocal changes may be evident in leads aVR and V1. These reciprocal changes further support the diagnosis of acute pericarditis.
Other ECG Findings
Besides the aforementioned patterns, additional ECG findings that can be observed in acute pericarditis include T wave inversions, PR interval prolongation, and low voltage QRS complexes. These findings may vary among individuals and should be considered alongside the characteristic ST segment changes.
By familiarizing yourself with these common ECG patterns in acute pericarditis, you will be better equipped to identify and differentiate this condition from other cardiac disorders. However, it is crucial to remember that an accurate diagnosis requires a comprehensive evaluation that combines clinical presentation, patient history, and ECG findings.
