Let’s take a look at why is my heart beating so fast? and Should I be worried if the heartbeat is rapid?

A fast heartbeat refers to a person’s heart beating faster than usual. There are many possible causes.An average resting rate for adults is approximately 60 to 100 beats/minute. A fast rate is a heart rate of more than 100 beats a minute. Tachycardia refers to a heart condition where your heart beats too quickly. Bradycardia is a condition in which your heart beats too slowly. Bradycardia is a heart rate that rests at less than 60 beats a minute.

This article delves into the details of why is my heart beating so fast.

What Is Racing’s Heart?

Normal hearts beat 60-100 times each minute. In medical terminology, a high heartbeat (known as tachycardia) beats more often than 100 times per minute. A rapid heartbeat can last anywhere from seconds to several hours. However, not all cases of a racing pulse are dangerous. You can have your heart rate race in everyday situations, even if you don’t have heart problems.

You might also consider keeping a record of your symptoms. Keep track of what you were doing when you first noticed your heart beating rapidly. It can be helpful for your doctor to record when your heart rate rises. If you feel your heart racing and not working out or stressed, it is time to see a doctor.

What Is A Dangerous Heart Rate?

Your heart rate, or the rate at which your heart beats each minute, is the time it takes to win. This number varies from person to person. Your overall health and activities can have an impact on your heart rate. For instance, exercise may cause it to rise while you’re doing cardio, and rest may cause it to slow down.

How To Measure Heart Rate?

How do you know your heartbeat? Whitney Thomas, an exercise physiologist with MD Anderson’s Cancer Prevention Center, said that the monitor is one of many ways to measure heart rate. This usually consists of a wristwatch or a belt that wraps around your arm or chest. The strap can also sync with a watch and other devices. Many wearable fitness trackers have heart rate monitors.

Your pulse is an excellent way to test your heart rate if your monitor doesn’t work. Use two fingers (your middle fingers and your index fingers) to locate the carotid vein, which is located below your throat. Then, please take 10 seconds to count how many beats it feels. Divide this number by six. That’s approximately the rate at which your heart beats each minute.

Several Heart Diseases Can Cause A Racing Heart

Caffeine, a stimulant, is found in many beverages such as tea, coffee, and certain sodas. Caffeine powder may also be available as a nutritional supplement.

2014 research found that even a small amount can increase the chances of someone developing atrial fibrillation. Atrial fibrillation causes irregular heartbeats, sometimes with abnormally rapid beats.

Another study was done in 2017 to test people’s breath for alcohol levels. The heart rate increased with increasing alcohol concentration, according to researchers.


Nicotine is an addictive chemical found in cigarettes. According to AHA’s research, nicotine can cause an increase in blood pressure and heartbeat. In 2016, research showed that nicotine could increase the heart rate by about 10-15 beats per minute (BPM).Trusted source. Researchers also found that the rate at which a person’s heartbeat and blood pressure increases depends on whether they inhale, smoke, or inhale nicotine.

Illegal Stimulants

Illegal stimulants like cocaine and amphetamines that can be used to increase heart rate may make it possible.

2014 Trusted Source Research found that people who take cocaine are more likely to have irregular or high heart rates.

Doctors may use amphetamines to treat ADHD or narcolepsy. There are several side effects that amphetamines, including: can cause

  • A headache
  • High blood pressure An increased heart rate
  • Mouth that is dry

This same study also showed that the average heartbeat increased throughout pregnancy. The average heartbeat at ten weeks was 77.3 beats per hour and rose to 86.1 by 40 weeks.

  • Breathing problem
  • Fever
  • A fast heartbeat
  • Confusion
  • Bloating
  • Irregular heartbeat is a condition in which the heartbeat is irregular.

An electrolyte analysis checks whether a person has enough electrolytes in their blood. Based on abnormal electrolyte levels, the doctor can recommend treatment.

Why is my Heart Beating so Fast: What Tests Do You Need?


A good record is a first and most important thing. Do you have symptoms such as dizziness, lightheadedness, fatigue, or passing out? Is there chest pain? Is the rapid heart rate constant or intermittent? Do the symptoms only manifest when the heartbeat is high? What happens when the heart rate increases?

This can be used to cross check with the monitor to identify any correlations.


This ultrasonographic scan of the Heart is used to examine the structure and functioning of the heart. It’s commonly performed in patients suffering from palpitations and rapid heartbeat.
