Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

Sen. Chunk Schumer has asked the U.S. Food and Drunk Administration (FDA) to investigate the high amount of caffeine found in energy drinks sold by Prime, a beverage brand founded by YouTube personalities Logan Paul and KSI. According to Schumer, the “eye-popping 200 mg of caffeine” found in a single Prime energy drink is troubling, especially for a product marketed primarily to children.

Energy drinks may damage the heart, researchers warn—should the FDA get involved?

The authors assessed 17 popular energy drinks, sharing their analysis in Food and Chemical Toxicology.
