"Tachycardia" or "Tachyarrhythmia" refers to a resting heart-rate near or over 100 BPM.

Tachycardia or tachyarrhythmia refers to a resting heart rate near or over 100 beats per minute (bpm), and the statement is true. In a normal healthy individual, the resting heart rate typically ranges between 60 and 100 bpm. When the heart rate exceeds this upper limit, it is considered tachycardia. Tachyarrhythmia specifically refers to an abnormal rhythm of the heart that results in a fast heart rate. Both conditions can be caused by various factors, including stress, anxiety, physical exertion, certain medications, or underlying medical conditions like heart disease or thyroid problems. It is important to monitor and address tachycardia or tachyarrhythmia, as sustained high heart rates can lead to complications like compromised blood flow, increased risk of blood clots, or heart failure.
