Heart Palpitations: Causes, Symptoms, and Treatment Options

Arrhythmia

Thank you for your response, Doctor.
I would like to ask another question.
I underwent a full body health check at Dong Yuan Hospital on August 19, where my pulse was 75 beats per minute.
Later, a neurologist prescribed Venlafaxine-XR 75mg, and after taking just one pill, my heart rate increased, and I experienced insomnia for a week.
Subsequently, I visited the neurology department at Shalu Tong Hospital, where the doctor measured my pulse at 114 beats per minute and prescribed Propranolol 10mg/tablet.
My heart rate is currently maintained between 90-110 beats per minute.
When going up and down stairs, my heart rate accelerates, I feel very hot, and I sweat a lot.
Previously, when I worked at my company, I could go up and down seven floors without getting breathless, but now, even walking a short distance at home makes me feel very tired.

Doctor, I have the following questions:
1.
Is the increased heart rate a side effect of the medication? Why does my heart rate remain elevated?
2.
Which specialty should I consult?
3.
Is there a possibility of heart issues, or did the medication just trigger them? My echocardiogram was normal.

4.
Can an elevated heart rate cause symptoms such as headaches, lower back pain, or diarrhea?
5.
Am I allowed to engage in stretching exercises or running?
Please take the time to answer my questions.
Thank you.

1.
Venlafaxine-XR can be used as a treatment for anxiety and depression.

2.
Your symptoms resemble anxiety rather than a cardiac issue; "palpitations" are a common symptom.
It is recommended to visit a neurologist to inform the physician about your medication reactions, as adjusting the medication may improve your condition.
Strenuous exercise is not advisable at this time, but gentle stretching and light jogging are acceptable.

More Info

Heart palpitations can be concerning and often lead to questions about their causes, symptoms, and treatment options. Based on your description, it seems you have experienced an increase in heart rate after starting a new medication, Venlafaxine-XR, which is an antidepressant that can sometimes lead to side effects such as increased heart rate (tachycardia) and insomnia.
1. Is the increased heart rate a side effect of the medication?
Yes, it is possible that the increased heart rate you experienced after taking Venlafaxine-XR is a side effect of the medication. Venlafaxine can affect neurotransmitters in the brain, which may lead to increased sympathetic nervous system activity, resulting in symptoms like tachycardia. If your heart rate remains elevated, it is essential to discuss this with your healthcare provider, as they may consider adjusting your medication or dosage.

2. Which specialist should you consult?
Given your symptoms of palpitations and the increase in heart rate, it would be advisable to consult a cardiologist. A cardiologist specializes in heart conditions and can perform further evaluations, such as an electrocardiogram (EKG), echocardiogram, or Holter monitor, to assess your heart's rhythm and function. Additionally, if your primary care physician or neurologist has concerns about the interaction between your medications and your heart rate, they may refer you to a cardiologist for further evaluation.

3. Is there a heart problem, or is it medication-induced?
While your echocardiogram results were normal, which is reassuring, the symptoms you describe could be related to the medication rather than an underlying heart condition. However, it is crucial to rule out any cardiac issues, especially since you are experiencing significant changes in your heart rate and physical endurance. The cardiologist will be able to determine if there is any underlying heart condition that needs to be addressed.

4. Can rapid heart rate cause other symptoms?
Yes, an increased heart rate can lead to various symptoms, including headaches, fatigue, dizziness, and even gastrointestinal issues like diarrhea. The body's response to a rapid heart rate can vary from person to person, and some individuals may experience discomfort or fatigue during physical activity, as you mentioned. It is essential to monitor these symptoms and discuss them with your healthcare provider.

5. Can you engage in stretching or running exercises?
Before resuming any exercise regimen, especially activities that may elevate your heart rate further, it is crucial to consult with your healthcare provider. They can provide personalized advice based on your current health status and heart rate. Generally, light stretching and low-intensity activities may be acceptable, but high-intensity exercises like running should be approached with caution until your heart rate is stable and you have clearance from your doctor.

In summary, your symptoms of increased heart rate and fatigue warrant further evaluation by a cardiologist. It is essential to communicate openly with your healthcare providers about your symptoms and any medications you are taking. They can help determine the best course of action to manage your heart health and overall well-being.
