The ECG shows low voltaged QRS-complexes in leads I, II, and III and a right axisdeviation. This is caused by the increased pressure on the right chamber. This leads to right ventricular hypertrophy. | |||

In case of a tamponade, fluid collects in the pericardium. The pericardium is stiff and the heart cannot pump, because it cannot relax as well. The ECG shows: | |||
