Low Blood Pressure and Slow Heart Rate: When to Seek Help - Cardiology

Hypotension and bradycardia?


Hello Doctor, for the past year or two, I have been monitoring my blood pressure, which is usually around 85/55 mmHg, and my heart rate is about 50 bpm.
Recently, I have been experiencing more severe symptoms of orthostatic hypotension; when I stand up, I often see black for 3 to 4 seconds and frequently feel my heart beating strongly, which is quite uncomfortable, although I don't feel any missed beats.
Additionally, since I lost 6 kg, I have been experiencing easy swelling.
Sometimes when I wake up in the morning, my face is completely swollen, and I also feel bloated in my lower abdomen, but I have very little urine output.
My mother and grandmother seem to have some heart issues; I recall that my mother has mitral valve insufficiency, but I'm not sure about my grandmother.
Should I undergo further examinations for these symptoms?

If symptoms do not improve, please go to the hospital for further examination.

When it comes to low blood pressure (hypotension) and a slow heart rate (bradycardia), it is essential to understand the potential implications for your health and when to seek further medical evaluation. Your reported blood pressure of 85/55 mmHg and heart rate of around 50 beats per minute, combined with symptoms like dizziness upon standing (orthostatic hypotension), palpitations, and swelling, warrant a careful assessment.

Firstly, low blood pressure can lead to inadequate blood flow to vital organs, resulting in symptoms such as dizziness, fainting, and fatigue. In your case, the episodes of feeling faint when standing up, along with the sensation of a strong heartbeat, suggest that your body is struggling to maintain adequate blood flow when you change positions. This can be particularly concerning if it leads to falls or injuries.

Bradycardia, defined as a heart rate of less than 60 beats per minute, can be benign in well-conditioned athletes but may indicate an underlying issue in non-athletes. The fact that you are experiencing palpitations and discomfort, especially after a recent weight loss, raises the possibility of an underlying cardiac condition. Given your family history of heart issues, including your mother’s mitral valve insufficiency, it is prudent to investigate these symptoms further.

The swelling you mentioned, particularly in the face and abdomen, could be related to fluid retention, which may be a consequence of low blood pressure or other underlying conditions such as kidney issues or heart problems. The fact that you are experiencing reduced urination alongside swelling is also concerning and should be evaluated.

In light of these symptoms, it is advisable to seek a comprehensive evaluation from a healthcare provider. This may include:
1. Blood Tests: To check kidney function, electrolyte levels, and other markers that could indicate underlying issues.

2. Electrocardiogram (ECG): To assess your heart's rhythm and identify any abnormalities that may explain your bradycardia and palpitations.

3. Echocardiogram: This ultrasound of the heart can help evaluate its structure and function, particularly in light of your family history of heart disease.

4. Holter Monitor: A 24-hour Holter monitor can provide more insight into your heart rate variability and any potential arrhythmias that might not be captured during a standard ECG.

In summary, while some individuals may experience low blood pressure and bradycardia without significant health risks, your symptoms and family history suggest that further evaluation is warranted. It is crucial to address these concerns proactively to rule out any serious conditions and to develop an appropriate management plan. Please consult with a healthcare professional who can guide you through the necessary tests and provide tailored advice based on your specific situation.
