The document discusses several electrocardiogram (ECG) findings and rhythms including ectopic atrial tachycardia, atrial tachycardia, electrical alternans seen in massive pericardial effusion which produces low QRS voltage, electrical alternans and tachycardia, escape rhythms like junctional escape rhythms where the pacemaker rate decreases down the conducting system, and ventricular escape rhythms. It also discusses the terminology of junctional rhythms and includes literature references.
