What has a heartbeat of 147 bpm?

A heartbeat of 147 beats per minute (bpm) is typical for a fetus during the early stages of pregnancy, particularly around the 10-12 week mark. In adults, such a heart rate could indicate a state of physical exertion, excitement, or anxiety. Additionally, certain medical conditions or arrhythmias can also cause elevated heart rates. Always consult a healthcare professional for accurate diagnosis and advice.
