Why When I Run My Heart Rate Suddenly Spikes Up from 120 to 170 bpm and After a Few Minutes While Still Running It Goes Down Suddenly to 120
When running, it is normal for heart rate to increase. However, a sudden spike from 120 bpm to 170 bpm followed by a rapid decrease to 120 bpm can be concerning. Several factors can contribute to this:
- Cardiac Arrhythmia: An irregular heartbeat can cause sudden changes in heart rate.
- Electrolyte Imbalance: Dehydration or insufficient electrolyte intake can lead to imbalances that affect heart function.
- Hormonal Changes: Adrenaline release during exercise can cause a temporary increase in heart rate, which can then decrease as the body adapts.
- Training Status: Individuals with lower fitness levels may experience more significant heart rate spikes during exercise.
- Medical Conditions: Underlying medical conditions such as thyroid issues or heart disease can also influence heart rate responses during exercise.
If you consistently experience sudden heart rate spikes and drops while running, consult a healthcare professional for evaluation to determine the cause and receive appropriate medical advice.
