Massive pericardial effusion produces a characteristic ECG triad of low QRS voltage, tachycardia, and electrical alternans. LITFL ECG Library
A review of the ECG characteristics of "fixed ratio blocks", i.e. second degree AV block with 2:1 or 3:1 conduction ratios.
Second degree heart block (2nd degree AV block) with a P:QRS ratio of 3:1 or higher, producing an extremely slow ventricular rate.
