Regular Coffee, Tea Intake Not Linked to PVCs in Cohort Study

Whether or not they have the jitters, most regular coffee drinkers can at least be assured the caffeine probably isn"t giving them extra heartbeats, at least according to an analysis based on a cohort from the prospective Cardiovascular Health Study.

There were no significant associations between intake of coffee, tea, or chocolate daily or periodically and hourly rate of premature atrial contractions (PACs) or premature ventricular contractions (PVCs). Nor were they associated with daily prevalence of supraventricular tachycardia (SVT).

Coffee intake up to four times weekly was marginally associated with an increase in runs of ventricular tachycardia in the study, published January 26, 2016 in the Journal of the American Heart Association.
