CT can detect the presence of a pericardial effusion; however, it is not accurate to estimate size. The 12-lead ECG may show low voltage, pericarditis (if present) or electrical alternans.

This ECG occurred in the setting of a large pericardial effusion causing cardiac tamponade. The pericardial effusion dampens the electrical signal on the ECG causing low voltage to be present (see ...

ECG and echocardiography was done at admission ... Prolonged QTc interval, pericardial effusion and diastolic dysfunction are associated with higher mortality.

The clinical diagnosis of acute pericarditis is based on simple criteria: typical chest pain, pericardial friction rub (Figure 2), widespread ST-segment elevation (Figure 3) and pericardial ...
