For most of human history, the heart was the essence of life, and yet, it would take centuries before its electrical signals were recorded. In this chapter, the author discusses the recording of the electrocardiogram (ECG), and nearly 60 years later, the birth of clinical cardiac electrophysiology ushered by the development of programmed electrical stimulation (PES) in 1967 followed a catheter technique to record electrical activity from discrete sections of the heart. These two pioneering studies would usher a new specialty in cardiovascular medicine, that of clinical cardiac electrophysiology. |
