A heart rhythm going below the baseline, often referred to as bradycardia, can be caused by various factors, including issues with the heart's electrical conduction system, certain medications, or underlying health conditions like hypothyroidism or Heart disease. It may also occur in well-conditioned athletes due to increased vagal tone. Symptoms can range from mild to severe, depending on the underlying cause and the degree of heart rate reduction. If persistent or accompanied by symptoms, it is essential to seek medical evaluation.
