Best treatments for bradycardia

Understanding bradycardia

"Bradycardia" means a slow heartbeat, and the category is wider than one diagnosis: it takes in sinus bradycardia (the heart's own pacemaker, the sinus node, firing slowly), sinus pauses and sinoatrial exit block, tachycardia-bradycardia syndrome, and atrioventricular (AV) block, in which beats from the upper chambers fail to reach the lower ones. The 2018 ACC/AHA/HRS guideline sets the definitions: sinus bradycardia is a sinus rate below 50 bpm, and a sinus pause is the sinus node depolarizing more than 3 seconds after the last atrial beat. The 50-versus-60 gap trips people up. StatPearls (NCBI Bookshelf) still describes the diagnosis as a 12-lead ECG showing normal sinus rhythm at a rate lower than 60 bpm, but notes in the same chapter that "there is a growing clinical consensus to lower the diagnosis threshold of sinus bradycardia to less than 50 bpm" — which is where the guideline landed. Either way, slow is not automatically abnormal: StatPearls states that sinus bradycardia is an incidental finding in many healthy adults, common in athletes and during sleep. The decisive question is symptoms, not the number. The same ACC/AHA/HRS guideline says that in sinus node dysfunction there is no established minimum heart rate or pause duration at which permanent pacing is recommended, and that establishing a temporal correlation between symptoms and the bradycardia is what matters. MedlinePlus (NLM) lists the symptoms of sick sinus syndrome as fainting or near-fainting, fatigue, dizziness or lightheadedness, and chest pain, and notes it most often occurs in people older than age 50. This is general information, not medical advice; talk to a clinician about your own heart rhythm.
