About RHR
Resting Heart Rate (RHR) measures the number of heartbeats per minute when an individual is at rest. It is a crucial indicator of cardiovascular efficiency and overall heart health. A lower resting heart rate is often associated with more efficient heart function and better cardiovascular fitness.
Reference Values
Optimal Range
30 - 50 bpm
Elite Value
30 bpm
Health Implications
High
Elevated levels may indicate stress, dehydration, or potential cardiovascular issues and should be monitored for any persistent changes.
Low
Low levels may be associated with bradycardia or an underactive thyroid and often require medical evaluation, especially if accompanied by symptoms like dizziness or fatigue.
Symptoms
High
May include fatigue, headaches, palpitations, shortness of breath, and chest discomfort.
Low
Can include dizziness, weakness, fainting (syncope), confusion, and pale skin.
