A high resting pulse rate (over 100 beats per minute) can stem from several factors. A normal resting heart rate is generally between 60 and 100 beats per minute, but this can vary between individuals. Several conditions and lifestyle choices can elevate this rate above the normal range.
Common Causes of Elevated Resting Heart Rate
-
Stress and Anxiety: Stress triggers the release of adrenaline, increasing your heart rate. [Source: Hackensack Meridian Health, Mayo Clinic, healthdirect] This is often a temporary increase, returning to normal once the stressor is removed.
-
Dehydration: Insufficient fluid intake can lead to a faster heart rate as the blood volume decreases, forcing the heart to work harder.
-
Caffeine and Alcohol: Excessive consumption of caffeine and alcohol can stimulate your heart, causing it to beat faster. [Source: Provided reference text]

Smoking and Tobacco Use: Nicotine in tobacco products is a stimulant that increases heart rate. [Source: Provided reference text]

Underlying Medical Conditions: Several heart conditions, including cardiomyopathy, heart attacks, and heart disease, can cause a persistently high resting heart rate.

Medications: Certain medications can have a high heart rate as a side effect. It's crucial to consult your doctor if you suspect medication is a contributing factor.
When to Seek Medical Attention
While a temporarily elevated heart rate due to stress or exercise is usually harmless, a consistently high resting heart rate requires medical evaluation. Consult your doctor if you experience:
- A persistently high resting heart rate (over 100 bpm)
- Dizziness or lightheadedness associated with a rapid heartbeat
- Chest pain or discomfort
- Shortness of breath
