Key result
The arrhythmogenic and electrophysiologic effects of caffeine were investigated in 19 participants, though results are not provided in the truncated abstract.
Leaves open caffeine's arrhythmogenic effects in humans; larger controlled trials needed before clinical guidance.
IT has been estimated that in a typical year Americans consume nearly 109 kg of coffee.1 In addition, large amounts of tea, cola, and other caffeinated substances are ingested. Caffeine has long been implicated in the causation of arrhythmias, but studies in human beings have been limited. This study was undertaken to determine the cardiac electrophysiologic effects of caffeine, as well as caffeine's arrhythmogenic potential, in normal volunteers and patients with heart disease. Methods Seven normal volunteers with a mean age of 24 years (range, 20 to 31) and 12 patients with a mean age of 43 years (range, 17 . . .

Dobmeyer et al. (1983) studied Normal volunteers and patients with heart disease (n=19). Caffeine was evaluated on Cardiac electrophysiologic effects and arrhythmogenic potential. The arrhythmogenic and electrophysiologic effects of caffeine were investigated in 19 participants, though results are not provided in the truncated abstract.
