• High-intensity interval training (HIIT).

However, it is necessary to gradually increase intensity to allow the body to adapt and avoid putting too much pressure on the cardiovascular system.

Benefits of exercising at the right intensity

• Supports more effective heart rate stabilization.
• Increases heart and lung endurance.
• Improves blood circulation.
• Helps control blood pressure.
• Helps lower resting heart rate over time.

Important note

Exercising harder is not always better. Maintaining an intensity appropriate for your age, physical condition, and health status is the determining factor for long-term effectiveness. If you are new to exercise or have a history of cardiovascular disease, prioritize moderate activity and gradually increase it as your body allows.

Choosing the right exercise intensity will help your heart become stronger every day, thereby supporting a natural reduction in fast heart rate and sustainably improving cardiovascular health.

Step 4: How to calculate target heart rate during exercise

Determine target heart rate for effective and safe exercise

Monitoring your target heart rate during exercise is a way to ensure you are exercising at the correct intensity, enhancing calorie burning efficiency, and improving cardiovascular health. When your heart rate stays within the appropriate range, your heart will be better trained without being overworked.

Step 1: Calculate maximum heart rate

Maximum heart rate is the highest number of times your heart can beat in one minute during maximum exertion.

Calculation formula:

Maximum Heart Rate = 220 - Age

Example:

• If you are 45 years old:
  • 220 - 45 = 175
  • Maximum heart rate = 175 beats/minute.

Step 2: Determine target heart rate zone

Once you know your maximum heart rate, you can calculate the appropriate heart rate zone for your exercise goals.

Moderate intensity exercise

• Approximately 50%–70% of maximum heart rate.
• Suitable for beginners, those looking to improve overall health, or support lowering resting heart rate.

Formula:

• Lower end = Maximum Heart Rate × 50%
• Upper end = Maximum Heart Rate × 70%

Example for a 45-year-old:

• 175 × 50% = 88 beats/minute.
• 175 × 70% = 123 beats/minute.

The target heart rate zone will be between 88–123 beats/minute.

High intensity exercise

• Approximately 70%–85% of maximum heart rate.
• Suitable for individuals with a good fitness base who want to improve cardiovascular endurance.

Formula:

• Lower end = Maximum Heart Rate × 70%
• Upper end = Maximum Heart Rate × 85%

Example for a 45-year-old:

• 175 × 70% = 123 beats/minute.
• 175 × 85% = 149 beats/minute.

The target heart rate zone will be between 123–149 beats/minute.

How to monitor heart rate during exercise

• Use a smartwatch or fitness tracker.
• Check pulse at the wrist or neck during short breaks between exercises.
• Monitor regularly to adjust exercise intensity as needed.

Benefits of exercising within the target heart rate zone

• Increases exercise effectiveness.
• Supports heart rate stabilization in the long run.
• Enhances cardiovascular endurance.
• Reduces the risk of overtraining.
• Helps control weight and blood pressure more effectively.

When chest pain, shortness of breath, fainting, or symptoms suspected of a heart attack appear, the top priority is always to access emergency medical services for timely evaluation and treatment.

Early recognition of warning signs can help save lives, limit heart damage, and increase the chances of better recovery after serious cardiovascular events.

Step 3: Consult a doctor before self-treating

Talk to your doctor before applying home remedies for a fast heart rate

Methods such as dietary adjustments, exercise, supplements, or lifestyle changes can help reduce a fast heart rate in many cases. However, before applying any measures, you should consult your doctor to ensure they are appropriate for your health condition.

Why consult a doctor?

• Determine the actual cause of the fast heart rate.
• Assess the safety of home treatment methods.
• Detect underlying cardiovascular diseases or health problems.
• Develop a personalized plan to improve your heart rate.

In some cases, self-applying supportive measures may not yield desired results or even worsen the condition.

Provide complete health information to your doctor

During your visit, share details about:

• The symptoms you are experiencing.
• History of cardiovascular disease or other medical conditions.
• Medications you are currently taking.
• Dietary supplements or herbs you are taking.
• Your daily eating, exercise, and lifestyle habits.

This information helps the doctor make a more accurate assessment and provide appropriate guidance.

Be cautious with dietary supplements

Many people choose supplements such as:

• Magnesium.
• Potassium.
• Calcium.
• Other vitamins and minerals.

However, some products may interact with medications or affect existing health conditions. Therefore, you should not use them on your own without professional medical advice.

Exercise correctly to protect your heart

Although regular exercise helps stabilize heart rate and improve cardiovascular health, overexertion can put significant strain on the heart, especially in people with underlying heart conditions.

You should talk to your doctor to find out:

• Suitable types of exercise.
• Safe exercise intensity.
• Ideal exercise duration.
• How to monitor your heart rate during exercise.

This helps limit risks and optimize exercise effectiveness.

Important note

If tachycardia, palpitations, or heart fluttering occur frequently, persistently, or are accompanied by symptoms such as chest pain, shortness of breath, dizziness, or fainting, seek medical attention promptly instead of relying solely on home remedies.

Consulting a doctor before making changes to your diet, exercise routine, or using supplements is an important step to help you lower your heart rate safely, effectively, and in a way that suits your health condition.

Step 4: Follow-up periodically to control heart rate

Maintain regular follow-up appointments as scheduled by your doctor

If you have been diagnosed with tachycardia or arrhythmia, regular follow-up appointments play an important role in monitoring and treatment. These check-ups help the doctor assess treatment effectiveness, monitor disease progression, and detect early changes that could affect cardiovascular health.

Why is frequent follow-up necessary?

• Monitor the stability of your heart rate.
• Evaluate the effectiveness of medications or current treatment methods.
• Control related underlying conditions such as hypertension, cardiovascular disease, or thyroid disorders.
• Early detection of complications or abnormal signs.

Adhering to your appointment schedule helps make the treatment process more effective and limits the risk of disease progression.

Adhere to home treatment guidelines

In addition to follow-up appointments, you should fully implement the recommendations from your doctor, such as:

• Take medication at the correct dose and time.
• Maintain a healthy diet.
• Exercise appropriately for your health condition.
• Limit factors that can cause a fast heart rate such as stress, lack of sleep, or excessive caffeine consumption.
• Monitor heart rate and any unusual symptoms at home.

Report new symptoms immediately

During monitoring, actively contact your doctor if:

• New symptoms appear that you haven't experienced before.
• The condition of tachycardia occurs more frequently.
• Episodes of palpitations or heart fluttering last longer than usual.
• Shortness of breath, chest pain, dizziness, or fainting occur.

Timely reporting of these changes helps the doctor adjust the treatment plan more appropriately.

Don't hesitate to ask questions

You don't need to wait until your next follow-up appointment to ask your doctor questions. If you have any concerns about:

• Medication.
• Diet.
• Physical activity.
• Symptoms you are experiencing.
• Home heart rate monitoring results.

Actively contact or schedule an appointment for timely consultation.

Benefits of regular health monitoring

• Supports long-term heart rate stability.
• Reduces the risk of cardiovascular complications.
• Increases treatment effectiveness.
• Improves quality of life.
• Helps patients be more proactive in their health care.

Regular follow-up and maintaining communication with your doctor are important parts of controlling tachycardia. Close cooperation between the patient and medical staff will help detect potential problems early and protect cardiovascular health more effectively.

Avoid tobacco to protect your heart rate

Quit smoking to help lower your heart rate

Tobacco is one of the leading harmful factors to the cardiovascular system. Whether it's cigarettes, e-cigarettes, or other nicotine-containing products, regular use can increase the burden on the heart and blood vessels. If you want to lower your heart rate and improve cardiovascular health, limiting and eventually completely quitting tobacco is a very important step.

How does nicotine affect heart rate?

• Constricts blood vessels.
• Impairs blood circulation in the body.
• Makes the heart work harder to pump blood.
• Increases heart rate and blood pressure.
• Increases the risk of cardiovascular diseases over time.

Frequent exposure to nicotine can cause the heart to work continuously under stress, thereby negatively affecting long-term cardiovascular health.

Benefits of quitting smoking

• Helps stabilize heart rate.
• Improves blood circulation.
• Reduces pressure on the heart and blood vessels.
• Helps control blood pressure.
• Reduces the risk of heart attack, stroke, and many other cardiovascular diseases.

Even people who have smoked for many years can still receive significant health benefits after quitting tobacco.

Effective ways to quit smoking

• Set a clear quit date.
• Avoid situations that trigger smoking habits.
• Increase physical activity.
• Practice deep breathing or meditation to reduce nicotine cravings.
• Seek support from family, friends, or healthcare professionals when needed.

Don't neglect regular health check-ups

While improving tachycardia, you should maintain health check-ups as advised by your doctor. Regular follow-ups help:

• Monitor heart rate progression.
• Evaluate the effectiveness of lifestyle changes.
• Control cardiovascular risk factors.
• Adjust the treatment plan as needed.

Important note

If fast heart rate, palpitations, or heart fluttering persist despite lifestyle changes, proactively discuss this with your doctor for appropriate evaluation and treatment.

Quitting tobacco combined with a healthy diet, appropriate exercise, and regular follow-ups are important steps to lower a fast heart rate, protect cardiovascular health, and improve long-term quality of life.
