    (a) First-degree heart block. The PR interval is longer than 0.2s. A QRS complex follows every P wave. (b) Second-degree heart block, Mobitz type 1. There is progressive lengthening of the PR interval until eventually a QRS is dropped. (c) Second-degree heart block, Mobitz type 2. The PR interval is uniform, but the QRS is intermittently dropped. (d) Third-degree heart block. The P waves are completely disassociated from the QRS complexes. All these ECG traces reprinted with permission by Remedica from Arrhythmia (Chapter 8) in E.A.
