The echocardiogram of the heart demonstrated the characteristic swinging along with alternating voltage on the ECG.

Causes

The two most common causes of electrical alternans are cardiac tamponade and pericardial effusion. In this case, the heart's pendulum-like motion and rotation from beat to beat, which the ECG electrodes detect as varying amplitudes, is what causes the classic ECG rhythm. In addition, electrical alternans can be observed in conduction and refractory changes in a variety of rhythms, including the ones previously mentioned, which causes the electrodes to detect a range of QRS amplitudes.
