Yes – more research declares a bit of caffeine is okey-dokey

❝ Many clinicians advise patients with atrial or ventricular arrhythmias to avoid caffeinated beverages, but recent research has shown that coffee and tea are safe and can reduce the frequency of arrhythmias…

Arrhythmias, or abnormal heart rhythms, cause the heart to beat too fast, slow or unevenly. While some arrhythmias may be harmless or even go unnoticed in patients, others can increase risk for sudden cardiac arrest. Atrial fibrillation (AFib), the most common heart rhythm disorder, causes the heart to beat rapidly and skip beats, and if left untreated, can cause strokes.

A single cup of coffee contains about 95 mg of caffeine and acts as a stimulant to the central nervous system. Once in the body, caffeine blocks the effects of adenosine, a chemical that can facilitate AFib…

❝ “Caffeinated beverages such as coffee and tea may have long term anti-arrhythmic properties mediated by antioxidant effects and antagonism of adenosine,” Dr. Peter Kistler said. “In numerous population-based studies, patients who regularly consume coffee and tea at moderate levels have a lower lifetime risk of developing heart rhythm problems and possibly improved survival.”

One of those cultural questions I try to stay up-to-date with. Over the past 40 years, a bit of caffeine consumption seems to be staying well ahead of the abstinence crowd.
