May support moderate caffeine use in IHD without arrhythmia concern; leaves open confirmation in prospective trials.
Does moderate caffeine ingestion increase the frequency or severity of cardiac arrhythmias in normal persons or patients with heart disease?
Moderate caffeine ingestion does not increase the frequency or severity of cardiac arrhythmias, even in patients with ischemic heart disease or pre-existing ventricular ectopy.
Martin G. Myers (1991) conducted a review in Cardiac arrhythmias. Caffeine was evaluated on Frequency or severity of cardiac arrhythmias. Moderate ingestion of caffeine (up to 500 mg daily) does not increase the frequency or severity of cardiac arrhythmias in normal persons or patients with ischemic heart disease.
