Yes, pulse rate is not the same as heart rate. Pulse rate refers to the number of times your arteries expand and contract per minute as blood is pumped through them, which can be measured at various points on the body. Heart rate specifically refers to the number of times your heart contracts and relaxes per minute, which can be measured using an electrocardiogram (ECG) or heart rate monitor. While they are closely related, they are not identical because the pulse rate includes the time it takes for blood to travel from the heart to the measurement point and back, whereas heart rate measures the heart's own contractions.
