Coughing is a common reflex that helps clear the airways of irritants, mucus, and foreign particles. It is a natural and essential process that keeps the respiratory system healthy. However, coughing can sometimes cause discomfort, pain, and other symptoms, especially if it occurs frequently or intensely. One of the potential effects of coughing is an increased heart rate, which can be concerning for some people.
When a person coughs, the diaphragm and chest muscles contract forcefully, causing a sudden and brief increase in intrathoracic pressure. This pressure change can affect the heart and blood vessels, leading to changes in heart rate and rhythm. In some cases, coughing can trigger a reflex called the Bezold-Jarisch reflex, which involves a sudden and transient decrease in heart rate, followed by an increase. This reflex is more likely to occur in people with pre-existing heart conditions or nerve damage.
While coughing-induced changes in heart rate are usually temporary and harmless, they can be problematic in certain situations. For example, people with heart failure, arrhythmias, or other cardiac conditions may experience more severe and prolonged cough-related symptoms, such as shortness of breath, chest pain, and fatigue. In some cases, coughing can also indicate worsening heart function or medication side effects, which require prompt medical attention.
Key Takeaways
- Coughing can cause a temporary increase in heart rate due to changes in intrathoracic pressure and the Bezold-Jarisch reflex.
- People with pre-existing heart conditions or nerve damage may be more susceptible to cough-related cardiac symptoms.
- Persistent or severe coughing in people with heart failure or other cardiac conditions may indicate worsening heart function or medication side effects, which require medical evaluation.
Physiological Response to Coughing
Cough Reflex and Heart Rate
Coughing is a reflex action that expels air from the lungs with a sudden explosive sound. It is a normal physiological response to clear airways of irritants, excess mucus, and foreign particles. During coughing, there is a sudden increase in intrathoracic pressure, which results in the activation of baroreceptors and sympathetic nervous system. This activation leads to an increase in heart rate.
The cough reflex is initiated by the stimulation of cough receptors located in the airways. These receptors are sensitive to mechanical, chemical, and thermal stimuli. The afferent impulses from these receptors are transmitted to the cough centre located in the medulla oblongata of the brainstem. The cough centre then activates the efferent pathways that lead to the contraction of respiratory muscles, resulting in coughing.
Impact on Blood Pressure and Circulation
Coughing can have a significant impact on blood pressure and circulation. The sudden increase in intrathoracic pressure during coughing can cause a decline in venous blood return. This can lead to a decrease in cardiac output and arterial hypotension. However, there is a compensatory increase in heart rate that helps to maintain blood pressure.
Studies have shown that coughing can cause a sustained increase in heart rate in the absence of arterial hypotension. This suggests that the increase in heart rate during coughing is not solely due to the activation of baroreceptors. It is likely that other factors such as sympathetic nervous system activation and release of catecholamines also contribute to the increase in heart rate.
In conclusion, coughing can cause an increase in heart rate due to the activation of baroreceptors and sympathetic nervous system. It can also lead to a decline in venous blood return and arterial hypotension. However, the compensatory increase in heart rate helps to maintain blood pressure. It is important to note that coughing can have different physiological effects in different individuals depending on their health status. Therefore, it is recommended to seek medical advice if coughing persists or is accompanied by other symptoms.
Cough-Related Cardiac Conditions
Cardiac Cough
Cardiac cough is a common symptom of heart failure that can cause a persistent, dry cough. It is caused by the buildup of fluid in the lungs, which can lead to coughing. Cardiac cough can also be a sign of other heart conditions, such as arrhythmias or palpitations. Patients with cardiac cough should seek medical attention to determine the underlying cause of the cough, as it may be a sign of a more serious condition.
Heart Failure and Coughing
Heart failure is a chronic condition that occurs when the heart is unable to pump enough blood to meet the body’s needs. Coughing can be a symptom of heart failure, as the buildup of fluid in the lungs can cause coughing. Patients with heart failure may also experience shortness of breath, fatigue, and swelling in the legs and ankles. Treatment for heart failure may include medication, lifestyle changes, and in some cases, surgery.
Cough and Cardiac Arrhythmias
Cardiac arrhythmias are abnormal heart rhythms that can cause a variety of symptoms, including coughing. Patients with arrhythmias may experience palpitations, dizziness, and shortness of breath, in addition to coughing. Treatment for arrhythmias may include medication, lifestyle changes, and in some cases, surgery.
It is important to note that while coughing can be a symptom of cardiac conditions, it can also be caused by other factors, such as respiratory infections or allergies. Patients who experience persistent coughing should seek medical attention to determine the underlying cause of the cough.

Clinical Assessment and Diagnosis
Symptoms and Signs
Coughing is a common symptom that can be caused by various underlying conditions, including respiratory infections, allergies, and asthma. In some cases, coughing can also be a sign of heart dysfunction. When coughing is associated with heart dysfunction, it may be accompanied by other symptoms, such as shortness of breath, fatigue, dizziness, and chest pain.
Medical Evaluation
When a patient presents with coughing, it is important for a medical professional to perform a thorough evaluation to determine the underlying cause. A medical evaluation may include a physical examination, medical history review, and diagnostic tests, such as chest X-rays, blood tests, and electrocardiograms (ECGs).
If heart dysfunction is suspected, a referral to a cardiologist may be necessary. A cardiologist is a medical doctor who specializes in the diagnosis and treatment of heart conditions. The cardiologist may perform additional tests, such as echocardiograms and stress tests, to evaluate the function of the heart.
When to Consult a Doctor
If coughing persists for more than a few weeks or is accompanied by other symptoms, such as shortness of breath, chest pain, or fatigue, it is important to consult a doctor. In addition, if coughing is associated with heart dysfunction, it is important to seek medical attention promptly.
It is important to note that coughing can also be a side effect of certain medications, such as ACE inhibitors, which are commonly used to treat high blood pressure and heart failure. If a patient is taking medication and experiences coughing, it is important to consult a doctor to determine if the medication is the cause of the coughing.
Management and Treatment
Coughing can cause an increase in heart rate, and managing this condition is essential to prevent further complications. The management of cough-induced increased heart rate involves medication and therapies, lifestyle modifications, and monitoring and long-term care.
Medication and Therapies
In some cases, medication and therapies may be necessary to manage cough-induced increased heart rate. Diuretics can be used to reduce fluid buildup in the lungs and heart, while ACE inhibitors and beta-blockers can help to regulate heart rate and blood pressure.
It is important to note that medication should only be prescribed by a qualified healthcare professional and taken as directed. Patients should not adjust their medication dosage without consulting their doctor first.
Lifestyle Modifications
Lifestyle modifications can also play a significant role in managing cough-induced increased heart rate. Patients can reduce their risk of complications by avoiding triggers that can cause coughing, such as smoke, pollution, and allergens.
Additionally, patients can make lifestyle changes such as quitting smoking, maintaining a healthy weight, and engaging in regular exercise to reduce their risk of complications.
Monitoring and Long-Term Care

Patients should work closely with their healthcare provider to develop a treatment plan that is tailored to their individual needs and circumstances.
Frequently Asked Questions
Does the act of coughing have an impact on one’s heart rate?
Coughing can cause a temporary increase in heart rate due to the sudden increase in intrathoracic pressure. This is because the act of coughing causes the chest muscles to contract forcefully, which can stimulate the sympathetic nervous system and lead to an increase in heart rate. However, this increase in heart rate is usually short-lived and should not be a cause for concern.
Is there a correlation between having a cold with cough and experiencing an elevated heart rate?
Having a cold with cough can lead to an elevated heart rate due to the body’s immune response to the infection. This immune response can cause inflammation and increased production of cytokines, which can activate the sympathetic nervous system and lead to an increase in heart rate. However, this increase in heart rate is usually mild and should not be a cause for concern.
Are dry coughs associated with the occurrence of heart palpitations?
Dry coughs are not typically associated with the occurrence of heart palpitations. However, in some cases, a persistent dry cough can be a symptom of an underlying heart condition, such as heart failure. If you experience heart palpitations along with a persistent dry cough, it is important to seek medical attention.
Can persistent coughing influence one’s blood pressure levels?
Persistent coughing can cause a temporary increase in blood pressure due to the sudden increase in intrathoracic pressure. However, this increase in blood pressure is usually mild and should not be a cause for concern. If you have an underlying heart condition, such as hypertension, it is important to monitor your blood pressure regularly and seek medical attention if it becomes elevated.
What are the reasons behind experiencing rapid heartbeat in conjunction with coughing?
Rapid heartbeat in conjunction with coughing can be caused by a number of factors, including the sudden increase in intrathoracic pressure, activation of the sympathetic nervous system, or an underlying heart condition. If you experience rapid heartbeat along with coughing, it is important to seek medical attention to determine the underlying cause.
How does one characterise a cough linked to cardiac issues?
A cough linked to cardiac issues is typically dry and persistent, and may be accompanied by other symptoms such as shortness of breath, fatigue, and swelling in the legs and ankles. If you experience a persistent cough along with these symptoms, it is important to seek medical attention to determine if there is an underlying heart condition.
