While experiencing a fast heart rate happens when you are physically active and is a natural occurrence, there are situations when you should seek medical care for this symptom.
People who are physically active and live in Las Vegas where there are often extreme temperatures, periods of dehydration, and many high-intensity sports need to know when to be concerned about a rapid heartbeat. Sahara West Urgent Care provides non-emergency immediate walk-in physical examination services to assess heart-related symptoms and help determine whether or not they pose any risk to you while participating in physical activities.
What Is a Rapid Heartbeat During Exercise?
Tachycardia is characterized by a fast heart rate (>100 BPM). A naturally fast heart rate occurs while exercising because your body is looking for additional oxygen and energy to fuel activity.
For example, it is normal and good for your cardiovascular fitness to have a higher heart rate during exercise than when at rest. The important factor to assess is how your heart functions before, during, and after exercising.
Normal vs. Abnormal Heart Rate
- Normal: Heart rate increases during exercise and returns to normal with rest
- Abnormal: Heart rate spikes suddenly, feels irregular, or does not slow down after activity
Understanding this difference is critical for athletes and fitness enthusiasts.
Common Causes of Rapid Heartbeat While Playing
There are multiple reasons that can lead to an increased heart rate while exercising:
1. Physical Exertion
The heart will pump faster during exercise (like running) to provide oxygen to the muscles needed for active movement.
2. Dehydration
Many people will experience fluid loss in hot climates like Las Vegas while working out. When a person becomes dehydrated, the heart has to work harder, which will also increase the heart rate.
3. Electrolyte Imbalance
Low sodium or potassium levels can cause a disruption in the heart rhythm resulting in a racing heart.
4. Stimulants
Stimulants such as caffeine, nicotine, and certain dietary/natural supplements can increase a person’s heart rate while involved in physical activity.
5. Stress and Anxiety
In a competitive environment, a person’s “fight-or-flight” response will be activated which leads to an increased heart rate.
6. Arrhythmias (Heart Rhythm Disorders)
Conditions such as:
- Supraventricular tachycardia (SVT)
- Atrial fibrillation (AFib)
can cause irregular or excessively fast heartbeats during exercise.
Symptoms That May Accompany a Rapid Heartbeat
If a person experiences the following symptoms with an increased heart rate, they should stop any physical activity immediately and be seen by a healthcare provider/physician:
- Dizziness/lightheadedness
- Faint or near-faint
- Chest pain or pressure
- Shortness of breath and/or nausea
- Tired or fatigued
When Should You Seek Immediate Medical Help?
The following situations should be taken most seriously as they indicate a life-threatening medical condition and require immediate medical assistance:
- Heartbeat so quick that it cannot be counted
- Palpitations suddenly starting or stopping
- Heart rate above 150 bpm while resting
- Heart rate remains above 100 bpm for 15 minutes while resting
- Chest pain radiating down the arm, neck, or jaw
- Difficulty breathing or fainting.
At Sahara West Urgent Care, we offer same-day walk-in evaluations in Las Vegas to quickly assess and manage these symptoms.

Diagnostic Tests for Rapid Heartbeat
In some cases, your doctor may suggest that additional tests be performed to assess your heart’s health:
Electrocardiogram (EKG)
Show your doctor if there is a problem with the electrical system that controls how your heart beats
Exercise Stress Test
Measure whether your heart is working well when you exert yourself during exercise
Blood Tests
Check for any of the following conditions:
- Anemia

Heart Monitoring Devices
Wearable or portable monitors track heart rhythm over time to detect abnormalities.
Is a Rapid Heartbeat Always Dangerous?
Many times a high heart rate while exercising is considered normal because the body is functioning appropriately – however, exercise begins to cause concern when the following is experienced:
- It occurs while just doing very little activity
- It felt abnormal or irregular
- It hasn’t gone back to your normal resting heart rate
- It has been accompanied by other symptoms.
Continual monitoring of the same heart response can distinguish between normal responses and be indicative of an undiagnosed heart disease.
How to Prevent Rapid Heartbeat Issues During Sports
By taking preventative measures, you may be able to lower the possibility of having a heart-related problem.
Stay Hydrated
Drink fluids enough to keep hydrated, especially when outside in high heat.
Avoid Excess Stimulants
Do not consume caffeine, energy drinks, or any other type of supplement prior to exercise.
Train Gradually
Do not increase your exercise strength or intensity too abruptly.
Know Your Target Heart Rate
Generally, the heart rate at which to be at your best will range from 64%-76%, based on what your maximum heart rate is (220 minus your age).
