A heart rate below 60 beats per minute is clinically diagnosed as bradycardia. Bradycardia can occur in normal, healthy individuals as well as in patients with organic heart disease.

In young adults, heavy laborers, and athletes who often exercise, the heart rate is generally below 60 beats per minute without any clinical symptoms, and it does not pose a risk to the body. This slower heart rate serves as a protection for the heart.

In patients with organic heart disease, a significant decrease in heart rate can lead to clinical symptoms such as palpitations, shortness of breath, and feeling of apprehension, necessitating the adjustment of heart rate under the guidance of a doctor using effective medications.
