Bradycardia
Type: Symptom
Definition
An abnormally slow resting heart rate, typically falling below sixty beats per minute.
Clinical Details
Thyroid hormones act as crucial biological accelerators for the cardiovascular system, dictating the speed and force of cardiac contractions. Without sufficient hormone levels, the electrical impulses within the heart's natural pacemaker fire much more slowly. This sluggish cardiac output heavily contributes to the patient's overall feelings of profound physical exhaustion.
