A slow heartbeat, known as bradycardia, can sometimes be associated with sensations of fluttering or palpitations, but the two are not the same. Fluttering sensations are often related to irregular heartbeats or arrhythmias, such as atrial flutter or atrial fibrillation.
If you are experiencing a slow heartbeat along with fluttering sensations, it's important to consult a healthcare professional. They can perform the appropriate tests to determine the cause of your symptoms and recommend any necessary treatment.
