Patient's question:
Can pericarditis be diagnosed with an electrocardiogram?Doctor's answer:
When there is pericardial effusion, it is evident that the limb lead QRS voltage is low. During significant effusion, the P wave, QRS wave, and T wave electrocardiogram are intermingled, often accompanied by sinus tachycardia. The diagnostic criteria for pericardial effusion, such as in patients with dyspnea, if typical signs are found during physical examination, such as jugular venous distension, expansion of the cardiac dullness border, and distant heart sounds, this diagnosis should be considered. Pericardial effusion can be diagnosed with magnetic resonance imaging of the heart.
