Cancer is a complex disease that affects various parts of the body. Some cancer treatments can cause side effects that affect the heart, including a slow heart rate. Slow heart rate, or bradycardia, is a condition where the heart beats less than 60 times per minute. Bradycardia can be caused by several factors, including ageing, heart disease, and certain medications.
Understanding the connection between cancer and heart rate is essential for cancer patients, survivors, and their caregivers. Cancer can affect the heart in several ways, including causing inflammation of the heart muscle, blocking blood vessels, and disrupting the heart’s electrical system. Additionally, some cancer treatments, such as chemotherapy and radiation therapy, can cause heart damage, leading to slow heart rate and other heart problems.
Symptoms of slow heart rate in cancer patients may include fatigue, dizziness, fainting, shortness of breath, and chest pain. Diagnosis of slow heart rate in cancer patients typically involves a comprehensive medical evaluation, including a physical exam, electrocardiogram (ECG), and other tests. Management and prevention of heart rate issues in cancer care may involve medications, lifestyle changes, and close monitoring of heart function during cancer treatment.

Understanding the Connection Between Cancer and Heart Rate
Impact of Cancer on Cardiovascular Health
Cancer is a disease that can affect any part of the body, including the heart. The relationship between cancer and cardiovascular health is strong and complicated. Cancer can have a significant impact on the heart, leading to various cardiac complications.
One of the most common ways cancer affects cardiovascular health is by causing inflammation in the heart muscles. This condition, known as myocarditis, can lead to cardiomyopathy, a disease that weakens the heart muscles. Cardiomyopathy can cause arrhythmia, bradycardia, and heart block, which can all result in a slow heart rate.
In addition, some cancer treatments, such as chemotherapy and radiation therapy, can also cause heart problems. Chemotherapy drugs, for instance, can damage the heart muscles, leading to heart disease. Radiation therapy, on the other hand, can cause scarring and inflammation in the heart, leading to heart cancer and other cardiac complications.
Common Cardiac Complications in Cancer Patients
Cancer patients are at a higher risk of developing cardiac complications due to the impact of cancer and its treatments on the heart. Some of the common cardiac complications in cancer patients include:
- Heart failure: Cancer patients are at a higher risk of developing heart failure due to the weakening of the heart muscles caused by cancer and its treatments.
- Arrhythmia: Cancer patients can develop arrhythmia, an irregular heartbeat caused by the damage to the heart muscles.
- Bradycardia: Cancer patients can experience a slow heart rate, known as bradycardia, due to the impact of cancer and its treatments on the heart.
- Heart block: Cancer patients can develop a heart block, a condition where the electrical signals that regulate the heartbeat are disrupted.
It is essential for cancer patients to monitor their cardiovascular health and discuss any concerns with their healthcare provider. Early detection and treatment of cardiac complications can improve the quality of life and reduce the risk of further complications.

Factors Contributing to Slow Heart Rate in Cancer Patients
Cancer patients may experience a slow heart rate due to various factors, including cancer treatment, medications, and associated health conditions. In this section, we will discuss the different factors that can contribute to a slow heart rate in cancer patients.
Effects of Cancer Treatment on Heart Rate
Cancer treatment, including chemotherapy and radiation therapy, can affect the heart rate of patients. Chemotherapy drugs such as anthracyclines (doxorubicin, adriamycin, epirubicin, daunorubicin, idarubicin, and mitoxantrone) and cisplatin can cause damage to the heart muscle, leading to arrhythmias and a slow heart rate.
High dose and prolonged use of chemotherapy drugs can also cause hypothyroidism, which can lead to a slow heart rate. Radiation therapy to the chest can also damage the heart muscle and cause arrhythmias.
Influence of Medications and Therapies
Medications used to treat cancer, such as targeted therapies, can also affect the heart rate of patients. Targeted therapies like trastuzumab, used to treat breast cancer, can cause arrhythmias and a slow heart rate.
Other medications used to treat cancer, such as beta-blockers, can also cause a slow heart rate. Patients with high blood pressure, diabetes, and obesity may be prescribed beta-blockers to manage their conditions.
Role of Associated Health Conditions
Associated health conditions like lung cancer, breast cancer, pancreatic cancer, kidney cancer, and leukemia can cause a slow heart rate in patients. Patients with these conditions may also have other health conditions like high blood pressure, diabetes, and obesity, which can contribute to a slow heart rate.
It is important for cancer patients to discuss any changes in their heart rate with their healthcare provider. A slow heart rate can be a sign of a serious condition and requires prompt medical attention.

Symptoms and Diagnosis of Slow Heart Rate in Cancer Patients
Cancer patients may experience slow heart rate, also known as bradycardia, as a result of their cancer or cancer treatment. Identifying slow heart rate and related symptoms is crucial for prompt diagnosis and treatment.
Identifying Slow Heart Rate and Related Symptoms
Slow heart rate can cause symptoms such as fatigue, dizziness, shortness of breath, fainting, syncope, palpitations, chest pain, confusion, and lightheadedness. These symptoms can occur at rest or during physical activity, and may be intermittent or persistent.
Patients who experience any of these symptoms should seek medical attention immediately. It is important to note that some cancer treatments, such as chemotherapy, can cause similar symptoms, so it is crucial to consult with a healthcare professional to determine the underlying cause.
Diagnostic Tests and Monitoring
Diagnostic tests such as electrocardiogram (ECG), blood tests, echocardiogram, and MRI may be used to diagnose slow heart rate in cancer patients. ECG is a non-invasive test that measures the electrical activity of the heart and can detect irregular heart rhythms.
Blood tests may be used to assess the levels of electrolytes such as potassium and sodium, which can affect heart function. Echocardiogram uses sound waves to create images of the heart and can detect abnormalities in heart structure and function.
MRI can provide detailed images of the heart and surrounding structures, and can detect abnormalities such as tumours or inflammation.
Once a diagnosis of slow heart rate is made, patients will be closely monitored by their healthcare team. Treatment options may include medication, pacemaker implantation, or other interventions depending on the underlying cause.
It is important for cancer patients to report any symptoms of slow heart rate to their healthcare team promptly to ensure timely diagnosis and management of this condition.
