A low heartbeat, or bradycardia, can be caused by various factors, including increased vagal tone, which slows heart rate, and certain medical conditions such as hypothyroidism, sleep apnea, or heart block. Medications like beta-blockers and calcium channel blockers can also lead to a decreased heart rate.
