Low Pulse Rate (Bradycardia) in Seniors: When to Be Concerned

A resting heart rate of 55 bpm is below the typical adult range (60–100 bpm) and warrants evaluation in an 80‑year‑old on long‑term antihypertensives.

Considerations

• Medication side effect (beta‑blockers, calcium channel blockers, digoxin).
• Electrolyte imbalance (high potassium).
• Thyroid dysfunction (hypothyroidism).
• Cardiac conduction issues.
• Deconditioning or excellent fitness (less likely at this age).

Action Plan

• Do not stop medications without doctor’s advice.
• Contact prescribing physician for possible dose adjustment.
• Monitor for dizziness, fainting, fatigue, shortness of breath.
• Seek emergency care if symptomatic.
