The video tutorial discusses three methods for monitoring heart rates: measuring the pulse on the wrist, using a stethoscope to count heartbeats, and employing an electrocardiogram (ECG) to check heart rhythm and electrical activity. The pulse is measured by counting beats for 30 seconds and multiplying by two. A stethoscope detects the lub-dubb sounds of the heart, while an ECG provides a visual trace of heartbeats, helping to assess heart health. The tutorial emphasizes the importance of accurate measurement and understanding the heart's function.
