You may be feeling your heart beating low because of a slower-than-normal heart rate, also known as bradycardia. This can be due to several factors, most commonly a problem with your heart's natural pacemaker.
Possible Causes of Feeling a "Low" Heartbeat
Feeling your heart beat low can be subjective, but often refers to a sensation of a slow or weak pulse. Here are potential reasons for this perception:
-
Bradycardia: A heart rate below 60 beats per minute is generally considered bradycardia. While it's normal for well-trained athletes, in others, it can indicate an underlying issue.
-
Sinus Node Malfunction: The sinus node is the heart's natural pacemaker. If it's not working properly, it can lead to a slower heart rate. This could involve:
- Sinus bradycardia: A slower-than-normal sinus rhythm.
- Sinus arrest: Temporary pauses in the sinus node's activity.
- Sinoatrial block: Disruption of the electrical signal as it leaves the sinus node.
-
Heart Block: This occurs when electrical signals are partially or completely blocked from traveling from the atria (upper chambers) to the ventricles (lower chambers) of the heart. This can result in a slow heart rate.
-
Medications: Certain medications, such as beta-blockers, calcium channel blockers, and digoxin, can slow down your heart rate.
-
Electrolyte Imbalance: Imbalances in electrolytes like potassium or calcium can affect heart rhythm and rate.
-
Hypothyroidism: An underactive thyroid gland can sometimes lead to a slower heart rate.
-
Vagal Stimulation: Increased vagal nerve activity can temporarily slow the heart rate. This can be triggered by things like straining during bowel movements (Valsalva maneuver).
-
Underlying Heart Condition: In some cases, a "low" feeling heartbeat could be related to a structural heart problem or other heart condition.
What To Do
If you are concerned about feeling your heart beat low, especially if you experience symptoms like dizziness, lightheadedness, fainting, chest pain, or shortness of breath, it's essential to:
- Consult your doctor: They can evaluate your heart rate, rhythm, and overall health to determine the cause.
- Describe your symptoms: Be prepared to describe the feeling you're experiencing, how often it occurs, and any associated symptoms.
- Mention medications: List all medications, supplements, and over-the-counter drugs you are taking.
- Consider an ECG: Your doctor may order an electrocardiogram (ECG) to record your heart's electrical activity. They might also recommend further testing.
Feeling your heart beat low can be a sign of a slower-than-normal heart rate, which can be caused by various factors, including issues with the sinus node, heart block, medications, electrolyte imbalances, or underlying heart conditions. It's crucial to consult a healthcare professional for proper diagnosis and treatment.
