It is a natural bodily response that may indicate various underlying issues or lifestyle choices. Understanding what it means when your heart races is crucial for recognising when it may be a sign to seek medical attention.

What is an increased heart rate?

Increased heart rate, medically known as tachycardia, happens when the heart beats faster than the normal resting rate. For adults, a typical resting heart rate falls between 60 and 100 beats per minute. When your heart rate exceeds this range, it can create uncomfortable sensations in the chest, often described as palpitations.

Several factors can contribute to a higher heart rate; physical activity, stress, anxiety, hormonal fluctuations, and existing medical conditions are common culprits. For instance, during intense exercise, the heart rate can soar to about 170 beats per minute in a healthy individual, whereas, in someone with anxiety, it might rise to 120 beats per minute during stressful situations.

Symptoms of Increased Heart Rate

Identifying the symptoms associated with an increased heart rate is vital for deciding when to seek medical help. Common symptoms include:

Racing Heartbeat: You may feel a quick and irregular pulse in your chest, which can be alarming.
Lightheadedness or Dizziness: This sensation can happen when blood flow decreases due to a rapid heart rate.
Shortness of Breath: You might find it hard to breathe even when at rest.
Chest Pain or Discomfort: While this could stem from anxiety, it might also indicate more significant health concerns that require attention.

Being aware of these symptoms can help you determine when it is time to consult a healthcare provider.

Causes of Increased Heart Rate

Increased heart rate has various causes, categorised into physiological and pathological factors.

Physiological Causes

These triggers typically do not signify any serious health issues:

Exercise: Engaging in physical activity demands more oxygen, which naturally increases heart rate. For example, a person running might experience a heart rate that soars to over 150 beats per minute.
Emotional Stress: Situations involving anxiety or panic can cause temporary spikes in heart rate, sometimes exceeding 100 beats per minute.
Stimulants: Substances like caffeine or nicotine can significantly elevate your heart rate; a single cup of coffee can increase it by around 20%.
Fever or Illness: Your body’s metabolic rate increases when you’re sick, leading to a higher resting heart rate.

Pathological Causes

These factors may indicate more severe health issues that require evaluation:

Anaemia: This condition reduces red blood cell count, prompting the heart to pump more rapidly to supply adequate oxygen. In severe cases, a heart rate of over 120 beats per minute may occur.
Hyperthyroidism: Too much thyroid hormone can accelerate heart rate and boost metabolism.
Arrhythmias: These irregular heartbeats disrupt normal rhythms and can lead to sustained tachycardia.
Heart Disease: Issues like coronary artery disease or congestive heart failure often present symptoms like palpitations and increased heart rate.

Understanding these causes helps individuals monitor their heart health and make informed decisions about seeking help.

When to Seek Medical Attention

It’s crucial to recognise when your heart rate necessitates professional evaluation:

Persistent Tachycardia: If your increased heart rate persists for long periods without an obvious reason, it’s wise to consult a healthcare professional.
Accompanying Chest Pain: Any discomfort alongside an increased heart rate should be checked out.
Fainting Spells: Sudden loss of consciousness or significant dizziness requires immediate assessment.
Palpitations with Other Symptoms: If you experience palpitations along with sweating, nausea, or extreme fatigue, it’s essential to talk to a physician.

Diagnosis of Increased Heart Rate

A medical evaluation typically starts with a detailed history and physical exam. Your doctor may recommend several tests to identify the cause of tachycardia, such as:

Electrocardiogram (ECG): This test monitors the heart’s electrical activity, helping to identify abnormal rhythms.
Holter Monitor: This portable ECG, worn for 24 to 48 hours, provides a comprehensive look at heart rhythms.
Blood Tests: Checking levels of thyroid hormones and haemoglobin can help uncover issues like anaemia or hyperthyroidism.
Echocardiogram: This ultrasound test can help detect structural heart problems.

Early diagnosis is crucial and can lead to better management and treatment plans for those experiencing increased heart rate.

Treatment Options

Managing increased heart rate typically involves addressing the underlying cause. Here are common approaches:

Medications: Drugs like beta-blockers or antiarrhythmics can help regulate heart rate.
Lifestyle Modifications: Lowering caffeine intake, managing stress, and maintaining a healthy lifestyle can help keep heart rates in check. A study shows that individuals who practice regular stress management techniques see a 30% reduction in episodes of increased heart rate.
Avoiding Triggers: Identifying personal triggers, such as certain foods or situations, can aid in managing symptoms.
Therapies: Cognitive-behavioural therapy (CBT) can assist in managing anxiety-related palpitations effectively.

Consulting a healthcare professional is fundamental for thorough evaluation and tailored treatment plans.

Understanding Your Heart Health

Increased heart rate or the feeling of palpitations can be puzzling, connecting both natural responses and potential health issues. By learning about the causes, symptoms, and signs that warrant medical attention, you can take proactive steps toward managing your heart health.
