Understanding a Low Heart Rate (25 BPM) in Elderly Women

A heart rate of 25 beats per minute (bpm) in an 89-year-old woman is critically low and requires immediate medical evaluation. Normal resting heart rate for this age group is typically 50–90 bpm (some sources cite 60–100 bpm).

Potential Causes of Bradycardia

• Medication side effects: Beta-blockers, calcium channel blockers, digoxin, blood pressure medications, anticoagulants.
• Cardiac conditions: Heart block, conduction abnormalities, heart failure, valve disease.
• Metabolic/electrolyte imbalances: Hyperkalemia, hypocalcemia, hypothyroidism.
• Other: Sepsis, sleep apnea, increased intracranial pressure, autonomic dysfunction.

Immediate Actions

1. Call emergency services if the person is symptomatic (confusion, fainting, shortness of breath, cold sweats, chest pain).
2. Do not stop medications without a doctor's guidance—sudden cessation can be dangerous.
3. Contact the prescribing physician immediately for medication review and dose adjustment.

Bradycardia at this level is a medical urgency. Prompt evaluation identifies reversible causes (often medication-related) and prevents complications like falls, syncope, or cardiac arrest.
