Rapid heart beat at rest due to tea or heart?

Tachycardia: Rapid heart rates can be either physiologically appropriate or inappropriate (pathologic). Examples of physiologic appropriate sinus tachycardia might be fast hr due to stress or caffeine. Pathologic tachycardia can involve a wide spectrum of arrhythmias coming either from the atria or ventricular locations.

Can be both: Coffee in excess amounts can stimulate the heart into a rapid heart rate. Hr can go up with intrinsic problems with the conducting system of the heart.

Depending how: Fast your heart is beating, you may want to get it checked out. Caffeine in tea can cause tachycardia, so eliminate it from your diet. If things don't improve or if they get worse, call your doctor.

Heart rate: Most resting heart rate normals are 80 to 100 bpm. Some people's resting heart rate is higher. Abnormal reasons for higher resting heart rate include anemia, hyperthyroidism, fever, ongoing inflammation or infection, dehydration and there is also a pathologic sinus tachycardia condition. You'd need to see a dr. And be evaluated if you're worried about your resting heart rate.
