Management of palpitations in a 65-year-old female depends on the underlying cause, the nature of the palpitations, and any associated symptoms or comorbidities (e.g., hypertension, diabetes, coronary artery disease).
| Pivotal Assessment | Findings | |
|---|---|---|
| History | ||
| Onset Type | Likely Causes | Clinical Implication |
|---|---|---|
| Sudden onset (comes on instantly, "out of the blue") | - Paroxysmal supraventricular tachycardia (PSVT) - Atrial fibrillation (AF) - Ventricular tachycardia (VT) | Suggests arrhythmia — often reentrant or due to abnormal foci. Needs ECG monitoring, maybe cardiology referral |
| Gradual onset (builds up slowly) | - Sinus tachycardia due to anxiety, anemia, fever, dehydration, hyperthyroidism | Often related to physiologic or systemic causes, rather than a primary cardiac rhythm issue |
At rest: May suggest arrhythmia, anxiety, or ectopy.
During exertion: Raises concern for ischemia, structural heart disease, or exercise-induced arrhythmia.
At night or while lying down: Can be due to ectopy, reflux, or heightened vagal tone.
Single, brief episodes: Often benign (e.g., PACs, PVCs).
Frequent or prolonged episodes: More concerning for arrhythmias like AF, SVT.
Sustained tachycardia >30 seconds: May require specific treatment (rate/rhythm control, anticoagulation if AF).
Triggered by caffeine, stress, alcohol: Suggests benign or anxiety-related cause.
Related to medications (e.g., bronchodilators): May be drug-induced.
Hormonal fluctuations (e.g., menopause): Can cause palpitations even without structural heart disease.
Understanding the onset helps you:
Decide urgency (emergency vs outpatient eval)
Choose appropriate testing (e.g., Holter, event monitor, stress test)
Prioritize cardiology referral
Tailor treatment (reassurance vs antiarrhythmics vs treating systemic cause)

++++++++++++++++++++++++++++++++++++++++++++History:
Onset, duration, frequency, triggers
Description: fluttering, pounding, irregular beats, etc.
Associated symptoms: chest pain, dyspnea, dizziness, syncope
Medication and supplement use (e.g., beta-agonists, decongestants, thyroid meds, caffeine)
Past Medical History:
History of heart disease, thyroid disease, electrolyte imbalance, anemia, or anxiety
Physical Exam:
Vital signs (especially heart rate, rhythm, BP)
Cardiopulmonary exam
Look for signs of thyroid disease, heart failure, or volume overload
Initial:
ECG (to look for arrhythmias, conduction issues, ischemia)
Electrolytes, glucose, renal function
Thyroid function tests (TSH, T4)
CBC (check for anemia)
Holter monitor (24-72 hr) or event recorder if palpitations are intermittent
If indicated:
Echocardiogram (evaluate structural heart disease)
Stress test (if ischemia is suspected)
| Cause | Management |
|---|---|
| Benign (e.g., PACs, PVCs) | Reassurance, lifestyle changes |
| Atrial Fibrillation/Flutter | Rate/rhythm control, anticoagulation as per CHA₂DS₂-VASc |
| Supraventricular Tachycardia (SVT) | Vagal maneuvers, beta-blockers or calcium channel blockers |
| Ventricular ectopy | Avoid stimulants, consider beta-blockers |
| Hyperthyroidism | Treat thyroid disease |
| Anemia | Iron supplementation or other treatments |
| Anxiety/Panic disorder | Behavioral therapy, SSRIs or benzodiazepines short-term |
| Medication-induced | Adjust or discontinue culprit drugs (e.g., bronchodilators, stimulants) |
Reduce caffeine, alcohol, nicotine
Regular exercise
Stress management (e.g., mindfulness, CBT)
Monitor symptoms (journal or use a wearable device)
Unexplained syncope or near-syncope
Structural heart disease on echo
Abnormal ECG
Persistent or symptomatic arrhythmias
Family history of sudden cardiac death
Would you like to tailor this to a specific clinical case or comorbidity (e.g., if she has diabetes, hypertension, or a history of coronary disease)?

Most palpitations are harmless, but if they occur frequently, are accompanied by symptoms like dizziness, chest pain, or shortness of breath, or are associated with an underlying condition, they should be evaluated by a healthcare provider.
